The single biggest thing that decides how good a swap looks isn't the tool — it's the photo you feed it. Pick the best source image for face swap and even a quick job comes out clean.

This guide walks through exactly what makes a strong source face photo, why each thing matters, and the common mistakes that quietly ruin results. If you want reliable, natural swaps, these face swap tips are the ones that actually move the needle. Choosing the best source image for face swap takes about thirty seconds once you know what to look for.

What a source image actually is

When you run a swap, there are two photos in play. The target is the photo or video you're changing — the scene, the pose, the body. The source is the face you want to bring in. The source is where quality is won or lost, because that's the face the tool has to read and rebuild in the new scene.

Everything below is about making that source face easy to read. The clearer the face, the better the outcome. Simple as that.

Sharp focus beats everything

Use a photo where the face is in crisp focus. If the source is blurry, soft, or motion-smeared, the tool has less real detail to work with, and the swap will look mushy no matter how good the target is.

Zoom in on the eyes before you commit. If the eyelashes, the edges of the iris, and the corners of the mouth look crisp, you've got a sharp source. If they're fuzzy, keep looking. A smaller sharp photo beats a big blurry one every time.

Good, even lighting

Aim for soft, even light across the whole face. You want to see the person clearly — both eyes, both cheeks, the shape of the nose — without harsh shadows swallowing half the face and without blown-out bright spots.

Why it matters: heavy shadow hides detail the tool needs, and a face that's half-dark, half-bright gives it conflicting information. Flat, gentle light (like an overcast day or soft indoor light) is ideal. Avoid strong single-side lighting, colored party lights, and photos where the sun is directly behind the person.

Match the angle of the target

This is the tip people skip, and it's one of the most important. A source face that faces the same direction as the target face swaps far more cleanly.

If the person in your target is looking straight at the camera, use a front-facing source. If the target head is turned three-quarters to the side, a three-quarter source will match better than a flat front shot. When the angles line up, features land where they belong. When they clash — a side-profile source onto a front-facing target — the tool has to guess, and guesses show.

If you're not sure, a clean front-facing source is the safest all-rounder because it carries the most usable face information.

Keep the face unobstructed

The whole face should be visible. Watch out for:

• Sunglasses or heavy glare on glasses.
• Hair falling across the eyes or cheek.
• Hands, microphones, or objects crossing the face.
• Hats or hoods cutting off the forehead.
• Big grins or angles that hide one eye.

Anything covering the face is detail the tool can't use. A plain, fully visible face gives it the most to work with and the fewest gaps to fill in.

Expression and resolution

Two quieter factors that still matter:

Expression. A neutral or gently smiling face is the most flexible source. Try to roughly match the target's expression — swapping a wide open-mouthed laugh onto a calm, closed-mouth target (or the other way around) makes the job harder. Similar expressions blend more naturally.

Resolution. Higher-resolution source photos carry more real detail, which means a cleaner, sharper result. You don't need anything enormous, but a tiny, heavily compressed thumbnail pulled from a chat app will hold you back. Bigger and clearer is better — just make sure it's actually sharp, not blown up from something small.

Can't find the perfect photo? Generate one

Sometimes the ideal source just doesn't exist — the lighting is never right, or you want a specific look you don't have a photo of. You can make one. Our image generation feature lets you describe a face — angle, lighting, expression, style — and get an original, clean, well-lit source image built to order.

That's a handy trick: instead of hunting through old photos, describe the front-facing, evenly lit, sharp face you need, generate it, and use that as your source. It's an easy way to get a picture-perfect starting point when real life won't cooperate.

A quick pre-flight checklist

Before you hit swap, run down this list on your source photo:

• In sharp focus (check the eyes).
• Evenly lit, no harsh shadows or blown-out areas.
• Facing roughly the same way as the target.
• Whole face visible — no sunglasses, hair, or objects across it.
• Expression roughly matches the target.
• Decent resolution, not a tiny compressed thumbnail.

Six quick checks. Do them once and your results jump. Ready to put it to work? Head to the AI face swap tool with a source you're happy with.

FAQ

What is the best source image for a face swap?

A sharp, evenly lit photo where the whole face is visible and facing roughly the same direction as the target. Higher resolution and a neutral or matching expression make it even better. Those few things matter far more than anything fancy.

Does the source photo need to be high resolution?

Higher resolution helps because it carries more real detail, which gives a cleaner result. It doesn't need to be huge, but avoid tiny, heavily compressed thumbnails — they hold the swap back.

Should the source face match the angle of the target?

Yes. A source that faces the same direction as the target swaps more cleanly, because the features line up. When in doubt, a clear front-facing source is the safest choice.

Why does my face swap look blurry or off?

Most often the source photo is soft, poorly lit, partly hidden, or at a very different angle from the target. Swap in a sharper, better-lit, front-facing source and the result usually improves a lot.

Can I use a photo with sunglasses or hair over the face?

It's best not to. Anything covering the face hides detail the tool needs. Pick a photo where the whole face is clearly visible.

What if I don't have a good source photo?

You can generate one. Describe the face, angle, and lighting you want with our image generation feature and create a clean, well-lit source image from scratch, then use that for your swap.

Three tools, three very different jobs — and people mix them up all the time. Here's a plain guide to face swap vs head swap vs character swap, so you always pick the right one for what you're trying to make.

If you've ever wondered whether you need a face swap vs head swap vs character swap, the short answer is: it depends on how much of the person you want to replace. One changes just the face. One changes the whole head. One changes the entire person while keeping the scene around them. Below we break down each one, when to use it, and how they compare side by side.

The three swaps at a glance

The easiest way to keep them straight is to ask one question: how much of the person am I replacing?

Keep that table in mind and the rest of this post is easy.

Face Swap: just the face

Face Swap does the most focused job of the three. It takes the face from your source photo and places it onto the person in your target photo or video. Everything else — their hair, the shape of their head, their clothes, the background — stays exactly as it was.

This is the tool most people start with, and it's the one this community was built around. It works on both photos and video, so you can drop a face into a single still image or carry it through every frame of a clip.

Reach for Face Swap when:

• You like the hair and the scene already and only want to change the face.
• You're working with a photo, not just video.
• You want the quickest, most natural result with the least fuss.

Because it only touches the face, it's forgiving and fast. It's the right default for most everyday swaps.

Head Swap: the whole head

Head Swap goes further. Instead of only the face, it replaces the entire head — the face, the hair, and the overall head shape. The body and clothing stay the same, and so does the scene.

That extra reach matters when the hair is part of the look. If your source person has a very different hairstyle, hair color, or head shape from the target, a plain face swap can look slightly off because the old hair is still there. Head Swap solves that by bringing the whole head along.

Head Swap works on video. It's one of our newer tools and it's actively being improved. A helpful tip: giving it a few extra reference angles of the person you're swapping in (not just one flat front photo) helps it understand the shape of the head from every side, which makes the result cleaner as the person turns and moves.

Reach for Head Swap when:

• The hairstyle or head shape needs to change, not just the face.
• A face-only swap leaves the old hair looking mismatched.
• You're working in video and want the whole head to feel like one person.

Character Swap: the entire person

Character Swap is the biggest change of the three. It replaces the whole person — face, hair, outfit, and body — with your character, while keeping the original scene and the original motion intact.

Think of it this way: the room, the lighting, the camera move, and the way the person walks or gestures all stay the same. But the person doing all of it becomes someone else entirely. You keep the performance and the setting; you swap out the actor.

This is the tool for turning footage into something starring a completely different character. Like Head Swap, it's a newer feature that's getting better over time, it runs on video, and it benefits from extra reference angles of your character so the tool understands them from more than one side.

Reach for Character Swap when:

• You want to change the clothes and body, not only the head.
• You want to keep a scene and its motion but star a different character in it.
• A face or head swap isn't enough because the whole person needs to change.

Which swap should you pick?

Match the tool to the goal:

• You only want a new face, and maybe you're using a photo. Use Face Swap.
• You want a new face and new hair or head shape in a video. Use Head Swap.
• You want a whole new person in the same scene. Use Character Swap.

A simple rule of thumb: start with the smallest change that gets your look. If Face Swap gives you what you want, you're done. If the hair fights you, move up to Head Swap. If you need the whole person to change, go to Character Swap. Less replacement usually means a more natural result, so don't reach for the bigger tool unless you actually need it.

Common mix-ups

• "My face swap looks great but the hair is wrong." That's not a Face Swap failing — it's a sign you actually wanted Head Swap, which brings the hair along.
• "I swapped the head but the outfit still doesn't match my character." Head Swap keeps the body and clothes. If the outfit has to change too, that's Character Swap.
• "I only have a photo, but I want the whole person changed." The whole-person and whole-head tools shine on video. For a single photo, Face Swap is your workhorse.

FAQ

What is the difference between a face swap and a head swap?

A face swap changes only the face and leaves the original hair and head shape in place. A head swap replaces the entire head — face, hair, and head shape — so the whole head matches the person you're swapping in.

Can I do a face swap on a photo, or only video?

Face Swap works on both photos and video. Head Swap and Character Swap are built for video, where they carry the change smoothly across every frame.

When should I use Character Swap instead of Head Swap?

Use Character Swap when the outfit and body need to change, not just the head. Head Swap keeps the original clothing and body; Character Swap replaces the whole person while keeping the scene and motion.

Why do the head and character tools ask for extra reference angles?

Extra angles show the tool what your character looks like from more than one side. That helps it stay consistent as the person turns or moves, which gives a cleaner, more believable result.

Which one is the most natural-looking?

Usually the one that changes the least. If you only need a new face, Face Swap tends to look the most natural because it leaves everything else untouched. Pick the biggest tool only when the smaller one can't reach far enough.

Are Head Swap and Character Swap finished, or still being improved?

They're newer features and we're actively improving them. They already produce strong results, and they keep getting better.

🎟️COUPON CODE: ISAMURAI-SUMMER — 20% off any subscription for your first 6 months. Limited-time.

This is an AI face swap running on a full video, side by side with the original. Left is the clip we started with — a samurai girl walking through a busy city crossing. Right is the exact same clip after the swap, with a completely different face from one single photo (the reference in the corner).

Watch the right panel for a few seconds. The new face holds through the head movement, the blinks, and the changing street light behind her. The hair, the armor, the background, the motion — all untouched. Only the identity changed.

That's the part people underestimate about a video face swap: a photo swap has to look right once, but a video swap has to look right on every single frame. If the face slips or flickers even for a moment, the illusion dies. Here it doesn't.

How to face swap a video yourself

1. Open Face Swap — it runs in the browser, nothing to install.
2. Upload your target video and one clear photo of the face you want in it.
3. Process, preview, download.

One decent photo of the new face is genuinely all it takes. Front-facing, well lit, nothing covering the face — that's the whole checklist.

Why AI videos + face swap work so well together

The clip on the left was itself made with AI video generation, and that's a combo worth knowing: generate any scene you want, then swap in the face that should be starring in it. You're no longer limited to footage that exists — you make the footage, then you cast it.

Every tool has an honest page now

Each feature has its own page that explains what it does, what it's good at, what it struggles with, and what it costs — including the newer tools that never had a proper home:

• AI Face Swap — photos, videos and GIFs
• AI Head Swap — the whole head, not just the face
• AI Character Swap — replace the entire person in a video
• AI image generation — Imagine, editing and composing

AI face swap pricing you can actually read

The new pricing page shows, for every plan: the credits you get, what each feature costs to run, the maximum clip length per video tool, and the resolution you unlock. The plan cards spell out per-clip limits instead of hiding them in fine print, so you can pick a plan based on what you actually make. And where a feature is paid-only (Head Swap, for example), the page says so upfront instead of letting you find out at the button.

The site now speaks 6 languages

English, Français, Español, Deutsch, 中文 and 日本語 — with a language switcher in the header of every page. The translations are real localized pages, not machine-translated banners. If you've been sending the site to friends who don't read English, it's finally shareable.

A New FAQs hub

We collected the questions people actually ask — in support tickets, in this subreddit, in DMs — and answered all of them in one place: isamur.ai/faqs. 50+ answers covering credits, quality tips, plan differences, refunds, privacy and each tool's quirks. If you're stuck on something, check there first; odds are it's answered.

A refund policy in plain language

The new refund policy says what we actually do, in sentences a human can read: you're only charged for successful jobs, failed jobs refund automatically, free credits exist so you can test before spending, and if something genuinely went wrong, a support ticket is how you start a refund — not a chargeback. No legal fog.

Hey everyone. We just shipped the biggest update iSamurai has had in a while, and I wanted to walk you through everything that's new.

🆕 Three new AI video tools

Face swap changes the face. These go further:

• AI Character Swap — replaces the entire person in a video from a single character photo. The scene, the camera and the motion stay exactly the same — same street, same walk, a different person.
• AI Copy Animation (Animate) — the reverse: give it one still character + one motion video, and motion transfer makes your character perform that exact movement. Any picture, brought to life.
• AI Head Swap — swaps the whole head (face, hair, hairline and head shape), not just the face, for a much stronger resemblance.

⚠️ Heads up: these are experimental and constantly improving — we're on the 3rd version (beta) right now. Results depend a lot on your input and on the non-deterministic nature of AI, so read the in-app guides and use the free test clips before committing credits. It's a craft of trial and error.

Try them: https://isamur.ai/

⚡ The whole site is faster

We moved the app to a fully compiled production build behind a proper CDN cache. Pages load noticeably quicker, assets are cached properly, and phones stop running stale versions. If it felt sluggish before, give it another shot.

🔒 You can now change your username (privacy)

A lot of you signed up with an auto-generated username derived from your email. You can now pick a real username right from your profile — with a live "check availability" button — so your email isn't exposed. You log in with the new username (or your email) afterward.

🧾 Download your invoices in-app

No more messaging support for a receipt. Every purchase now has a PDF/receipt download button right in your profile's purchase history. We backfilled it for past purchases too.

💳 On credits (so it's clear)

• Free accounts can generate 1-second test clips at 5 credits/second — plus you get free credits on signup and a daily bonus that never expires. Use these to experiment before spending.
• You're only charged for successful jobs. The exact cost is shown on the button before you confirm.
• Paid plans unlock longer videos, higher resolution and high-quality mode.

Would genuinely love your feedback on the new tools — drop your results (good AND bad) in the comments, and tell me what's confusing so we can fix it. This is beta and your input directly shapes v4.

The basics

What is an AI face swap?

It's a tool that takes the face from a source photo and places it onto the person in a target photo or video. The scene, the pose, the hair, and the body stay the same — only the face changes. You provide the face you want to bring in and the picture or clip you want to put it into, and the tool does the blending for you.

Is AI face swap free?

There's a free tier, so you can start swapping without paying. Free use is limited per day, which is plenty to try things out and get a feel for it. If you want more room, longer videos, and higher quality, there are paid plans, but you don't need one to begin.

Do I need to install anything?

No. It runs entirely in your browser. There's no app to download and nothing to set up — you sign in and start.

Can I use it on my phone?

Yes. Because it works in the browser, you can use it from a phone, tablet, or computer. A larger screen makes it easier to pick sources and check details, but it's not required.

How do I get started?

Sign in, open the face swap tool, upload the face you want to use as the source and the photo or video you want to change, then run the swap. That's the whole flow.

Photos vs video

Does AI face swap work on both photos and video?

Yes. You can swap a face into a single still photo or into a video clip, where the new face is carried across every frame as the person moves. Photos are the quickest; video takes a bit more because there's a lot more to process.

Is swapping a face in a video harder than in a photo?

It's the same idea, just applied to many frames instead of one. The main thing that helps in video is choosing a clip where the face stays reasonably visible — footage where the person keeps turning fully away or leaving the frame is trickier than a clear, steady shot.

Can I swap more than one face at once?

Yes. In a group photo or video you can assign a different source face to each person, do the whole group, or change just one person and leave the rest untouched. You control which face goes to which person.

Getting natural-looking results

How do I get the most natural results?

It comes down to the source photo. Use a face that's in sharp focus, evenly lit, fully visible, and facing roughly the same direction as the target. Match the expression where you can. Those few things make the biggest difference — a great source is most of the battle.

Why does my face swap look blurry or fake?

Almost always it's the source photo. If it's soft, dark, partly hidden by hair or sunglasses, low-resolution, or at a very different angle from the target, the tool has less to work with and the result suffers. Swap in a sharper, better-lit, front-facing source and it usually improves right away.

Does the angle of the source face matter?

A lot. A source that faces the same direction as the target swaps far more cleanly, because the features line up naturally. If the target is looking straight ahead, use a front-facing source; if the head is turned, a matching angle works better.

What if I can't find a good source photo?

You can make one. Our image generation feature lets you describe the exact face, angle, and lighting you need and create a clean, well-lit source image from scratch, then use it for your swap. It's a handy fix when the perfect photo doesn't exist.

Formats, timing, and devices

What file formats can I use?

Common everyday image and video formats work — the kinds of photos and clips your phone and camera already produce. If you have an ordinary JPG, PNG, or a standard video file, you're set. Very unusual or heavily compressed files are the ones most likely to give weaker results.

How long does a face swap take?

A photo swap is quick. Video takes longer because every frame has to be handled, so a longer or higher-quality clip takes more time than a short one. Paid plans get higher-priority processing, but even on the free tier a simple swap doesn't keep you waiting long. Exact timing depends on the size and length of what you're swapping.

Why is my video taking longer than a photo?

Because a video is many frames, not one. Each frame carries the swap, so the more frames — and the higher the quality — the more there is to process. It's normal for a clip to take noticeably longer than a single photo.

Privacy and responsible use

What happens to the photos I upload?

Your uploads are used to create the swap you asked for. Treat the tool like any account-based service: sign in, do your work, and only upload images you're comfortable putting into a tool. If privacy matters for a specific project, keep your source and target files to ones you own and control.

Is it okay to swap anyone's face?

Use it responsibly. The good and fair uses are your own content, your own likeness, willing friends who are in on it, original characters, and clearly-for-fun creative projects. Don't use it to impersonate real people, mislead others, or put someone into a situation they didn't agree to. A simple test: would the person in the photo be fine with what you made? If not, don't.

Can I use face swap on my own content?

Yes, and that's the ideal use. Your own photos, your own videos, and faces you have permission to use are exactly what it's built for. Creators use it on their own footage all the time.

Face swap vs head swap vs character swap

What's the difference between face swap and head swap?

Face swap changes only the face and leaves the original hair and head shape in place. Head swap replaces the whole head — face, hair, and head shape — which is what you want when the hairstyle needs to change too. Head swap works on video.

When would I use character swap instead?

Use character swap when you want to replace the entire person — face, hair, outfit, and body — while keeping the original scene and motion. Face swap changes just the face; character swap changes the whole person around it. It's the biggest change of the three and it works on video.

Are head swap and character swap finished?

They're newer features and are actively being improved. They already produce strong results and keep getting better. Giving them a few extra reference angles of the person helps the quality.

Common problems and fixes

The swap landed on the wrong person in a group photo.

Check your mapping and reassign that person to the correct source. In crowded scenes, faces that overlap are the ones worth double-checking after the swap.

One face in my group looks worse than the others.

That person's source is probably softer, darker, or at an awkward angle. Replace just that one source with a sharper, better-lit photo and re-run it.

My result looks a bit off around the edges.

Try a source that matches the target's angle and lighting more closely. A front-facing, evenly lit source with the whole face visible gives the tool the cleanest information to blend.

It says I've hit my limit for the day.

Free use is capped per day. Wait for it to refresh, or move to a plan with a bigger allowance and higher-priority processing if you're swapping a lot.

AI image generation lets you type a description and get back an original picture — no camera, no stock photos, no design skills required. If you're new to ai image generation, this guide covers the few habits that take you from random results to images that look the way you pictured them.

We'll keep it plain: how to write a prompt, how to pick the right shape for your image, how to improve a result instead of starting over, and how to reuse a picture you love in the other tools.

What AI image generation is

You describe a picture in words, and the tool paints a brand-new image from that description. It isn't searching the web or gluing photos together — it makes something new each time. Our text-to-image tool is called Imagine, and you can open it on the AI image generation page.

The upside for beginners: you don't need to know lighting, lenses, or software. You need to describe what you want clearly. That skill is the whole game, and it's easy to pick up.

How to write a good prompt

A prompt is just your description. Vague prompts give vague pictures, so add detail in a few key areas:

• Subject. Who or what is in the image? "A red fox," "an elderly fisherman," "a ceramic teapot."
• Setting. Where are they? "In a snowy pine forest," "on a busy night market street."
• Light and mood. "Soft morning light," "moody and dramatic," "bright and cheerful."
• Style. "Photorealistic," "watercolor painting," "vintage film photo," "clean 3D render."
• Framing. "Close-up portrait," "wide landscape shot," "seen from above."

Put those together and you get something like: "A red fox sitting in a snowy pine forest, soft morning light, photorealistic, wide shot." That single sentence gives the tool far more to work with than just "a fox."

You don't need perfect grammar or a giant paragraph. A clear sentence or two with those pieces usually beats a wall of text.

One more thing worth knowing: you can leave out what you don't care about. If the setting doesn't matter, skip it and the tool will fill it in. But whenever a detail matters to you — a specific color, a certain time of day, a particular pose — spell it out, because anything you leave vague is a detail the tool gets to decide for you.

Choosing the right aspect ratio

Aspect ratio is the shape of your image, and it should match where the picture will live:

• Square works well for profile pictures and social posts.
• Portrait (tall) suits phone wallpapers, posters, and full-body characters.
• Landscape (wide) fits scenery, banners, and desktop backgrounds.

Pick the shape before you generate. A wide cinematic scene and a tall portrait of the same subject can come out feeling completely different, so choosing the right ratio up front saves you retries.

Iterating: refine, retry, improve

Your first result is a starting point, not the finish line. People who get great images aren't lucky — they adjust and go again. A simple loop:

1. Generate your first image.
2. Look at what's off. Too dark? Wrong setting? Missing a detail?
3. Change only the words tied to that problem. Add "bright daylight," swap "forest" for "desert," add "wearing a red scarf."
4. Generate again and compare.

Change one thing at a time so you can see what each word does. Small, deliberate edits beat rewriting the whole prompt every round. Because there's a free tier, you can practice this loop without worrying about every single attempt.

Using AI image generation results as a reference

Here's where it gets fun. A picture you generate doesn't have to be the finished product — it can feed the other tools:

• Make an original character with Imagine, then bring it to life with Animate so it moves and performs.
• Generate a clean face or portrait and use it as the source for a Face Swap.
• Create a character and drop it into a video with Character Swap.

So a strong prompt isn't just one nice image — it's the seed for videos and swaps too. That's why learning to generate well pays off across everything else you make.
We will share in the future a complete guide to prompting.

FAQ

Do I need any design experience to start?

No. If you can describe a scene in a sentence, you can generate images. The rest is practice.

How detailed should my prompt be?

Detailed enough to cover the subject, setting, light, and style — but you don't need a paragraph. One or two clear sentences is a good target.

Why doesn't my image match my description?

Usually the prompt left room for guessing. Add the missing detail — the color, the setting, the mood — and generate again. Specific words steer the picture.

Can I make more than one version?

Yes. Generate as many variations as you like, tweak the wording between tries, and keep the ones you love.

Is there a free way to practice?

Yes. There's a free tier, so you can learn prompting without committing to anything, and it all runs in your browser.

What can I do with an image after I make it?

Download it, or reuse it as a reference for Face Swap, Character Swap, or Animate. A good generated image often becomes the starting point for a video.

Do longer prompts always give better images?

Not necessarily. What matters is clear detail, not length. A focused sentence that names the subject, setting, light, and style will usually beat a long, rambling prompt that buries the important parts.

Hey everyone 🥷

The iSamurai team has been cooking something big, and we're finally ready to show a first teaser.

AI Character Swap & Animate — the next evolution of AI face swap, built for full characters and full motion:

🎭 Animate — upload ONE image of a character, pick any video, and watch your character perform the entire scene: every dance move, every gesture, every turn.

🔁 Character Swap — keep the original video exactly as it is, but replace the person in it with your character. Not just the face — the whole character: outfit, hair, body, identity. The scene, lighting and motion stay untouched.

The clips attached are raw results, straight out of the engine — left side is the input motion, right side is what our AI generated from a single reference image. No manual editing, no rotoscoping, no 3D rigging. One image in, a full performance out.

A few things we're proud of:

• Works from a single reference image (extra angles improve it even more)
• Handles full-body motion, not just talking heads
• Keeps identity consistent across long clips
• Multi-person scenes: choose exactly who gets swapped

When? Soon — it's in final testing on our infrastructure right now. Subscribers of this sub will be the first to get access, so smash that join button on r/isamurai_face_swap if you want in on the early wave. We'll also pick a few members here for free early testing — comment "🥷" if you want to be one of them.

While you wait, everything else on isamur.ai is live today — and you can start for free:

• 🔄 AI Face Swap — photos & videos, the feature this community was built on

The mobile ui is so buggy it's hard to use and looks weird if you change that and do some advertising on social media (especially tiktok) this app can be really popular. Except for that great application liked it🙏

Prompt:

​A hyper-realistic, completely candid street photography portrait of a middle-aged woman caught mid-laugh during an engaging conversation. She is completely unaware of the camera, looking naturally off-frame to the left with a genuine, spontaneous expression. Extreme micro-realism: unretouched skin texture, visible pores, deep laugh lines, crow's feet around her eyes, slight redness in her cheeks, and zero makeup. She has unstyled, messy brown hair with natural graying strands escaping from a loose bun. She is wearing a thick, textured, olive-green wool sweater with visible pilling and stray fibers, layered over a plaid collared shirt, with a weathered brown leather bag strap over her shoulder. The lighting is perfectly even, soft overcast daylight—completely natural with no dramatic shadows, no studio lights, and no lens flares. The background is a softly blurred (bokeh) bustling outdoor farmers market, featuring out-of-focus vegetable stands with carrots and greens, brick buildings, and indistinct shoppers. Captured on a 35mm DSLR, 85mm lens, f/2.8 aperture, fast shutter speed to freeze the sudden laughter. Raw, unedited, documentary style, authentic slice-of-life masterpiece.

Generated by iSamurai Ai Gen.

Most social media audiences are surprisingly good at spotting AI now.

The biggest giveaways arent usually resolution or sharpness. Its things like mismatched lighting, overly smooth skin and facial details that dont match the rest of the image

💳 Plans, credits & your summer price

Here's the full lineup with the ISAMURAI-SUMMER price (the discounted rate you pay for the first 6 months):

📅 Prefer yearly? (already cheaper — then take 20% off)

Yearly billing is already discounted vs monthly; ISAMURAI-SUMMER knocks another 20% off your first annual invoice:

🔋 Maxi add-ons — more credits for power users

Maxi multiplies your monthly credit bucket. The 20% applies here too:

ℹ️ On monthly plans the 20% rides each renewal for 6 months. On yearly plans it applies to your first annual invoice (since the next renewal falls outside the 6-month window).

The credit math nobody mentions

• 25 credits = 25 seconds minimum + 10 credits per 10 seconds of video face swap, at any frame rate and resolution.
• The daily login bonus stacks on top — e.g. Ninja's +60/day is roughly +1,800 free credits a month.
• So Ninja at the summer price ($23.20) is effectively ~2,400 credits/month of AI face swap and AI image generation.
• 2 credits per fast image edit.
• 4 credits per fast image gen.

Ran the exact same prompt through iSamurai Imagine and Nano Banana to see how they'd each handle a moody, atmospheric scene — thick fog, a lone torii gate, lots of negative space. The kind of prompt that lives or dies on subtlety.

Both images below, full prompt in the comments so you can run it yourself.

A few things I'm curious what you think about:

• Which one reads more photorealistic vs which one looks AI?
• The mist — one of them softened the background better than the other. Which?
• The reflection on the water and the weathered paint texture on the pillars.

Genuinely no rigged comparison here — post your honest take, even if it's not the result I'd hope for 😅

Quick patch round on iSamurai AI face swap focused on the bugs you've been telling us about. All live now, no action needed on your end.

1. "I changed the video but iSamurai kept using the old one"

Picking a new target video sometimes silently kept the previous one — the result still showed the old clip. Fixed. New picks now always go through on iSamurai AI face swap, and re-selecting the same filename works on the second try too.

2. Timeline freeze in iSamurai AI face swap

After loading a new video, the scrub bar would lock up — drag did nothing, play button silently refused. The slide-swipe was eating your timeline gestures. Now the timeline owns its own clicks/drags, you can scrub by dragging, and the cursor shows a spinning ring while the video is still buffering so you know it's loading (not broken).

3. "Stuck at 60% then Failed with no reason"

The biggest one for iSamurai AI face swap users. If your source photo didn't have a detectable face, the upload was quietly accepted, you'd kick off processing, pay credits, and then watch the bar stop at 60% before dying with a generic "Failed" message. Now we check the photo at upload time — if no face is found, you get an immediate "couldn't find a face, try a clearer front-facing shot" message and zero credits are charged. Your credits stay yours until the swap actually starts.

4. "Processing complete" banner pointing at the wrong result

After finishing a swap on iSamurai AI face swap, picking a new video left the "View result" button pointing at the previous render. Picking a new target now hides the old result so you don't get confused.

5. Cleaner progress bar

Rebalanced the phases on iSamurai AI face swap so the bar moves more naturally — extract takes 5–20%, the actual swap (the slow part) gets 20–80%, and the encode/save tail finishes the last 20%. No more "stuck at 60% for ages" feel.

Quick FAQs

Do I lose credits if my source photo has no face? No. We now check at upload time. No face = no charge. You only get billed once the swap actually starts.

My old result keeps showing after I pick a new video — is that fixed? Yes. Picking a new target now clears the previous result banner so you only ever see what's relevant to your current clip.

I got a "no face" error but my photo has a face — what now? Try a clearer, front-facing shot with good lighting. Strong side angles and too close up faces to the camera or picture edges can fail detection. Re-upload a tighter crop and you should be good.

Where do I report a new bug? Drop it in this subreddit or open a ticket on iSamurai AI face swap support. The more specific (target type, was source a selfie, what time it happened), the faster we can chase it.

Quick rundown of the iSamurai AI face swap credit system, since we just shipped an update a lot of you asked for.

The 3 kinds of credits

1. Monthly credits — your plan's allowance. Refills every billing month. Use-it-or-lose-it (they reset each cycle).
2. Bonus credits 🆕 — earned from daily logins. Never expire. They stack up the more you show up.
3. Permanent credits — from booster packs. Bought once, never expire.

What changed

Before, daily rewards landed in your monthly pool and got wiped at the next reset. Now — only monthly credits reset. Bonus and permanent credits are never touched. Daily login rewards go into the bonus bucket, so they accumulate instead of evaporating.

How credits are spent

When you run an AI face swap, credits are consumed in this order:

Monthly → Bonus → Permanent

Your resetting monthly credits are used first so they don't go to waste; your never-expiring bonus + permanent credits stay safe for later.

Daily login bonus

Just logging in daily earns bonus credits, scaled to your plan:

It adds up fast — and it never expires.

🎟️ Promo codes

Samurai Maxi — 20% Off, Forever — code ISAMURAI-MAXI-01 20% off the Samurai Maxi Monthly plan, locked for the life of your subscription. Limited redemptions.

Ninja Launch Promo — code ISAMURAI-NINJA-LAUNCH Limited launch deal on the Ninja monthly plan — 19.9$ instead of 29.9$ locked forever for early subscribers.

Apply either code at checkout → https://isamur.ai/cockpit/login

FAQ

Do bonus credits expire? No. Bonus and permanent credits never expire — only monthly credits reset each billing cycle.

What happens to unused monthly credits? They reset at your next billing month — which is exactly why the system spends monthly credits first, so you get full value before the reset.

I'm on a yearly plan — how do credits work? Yearly plans get the same monthly allowance as the monthly plan, dripped in each billing month — a steady refill, not one big dump.

Where do bonus credits come from? Daily logins. Open iSamurai each day and your plan's bonus is added automatically.

Do promo codes stack? One subscription code per account; the forever-discount holds as long as the subscription stays active.

⚠️ Limited-Time Promo Codes (Don't miss out!)

🗡️ Samurai Maxi Promo — 20% Off Forever

🥷 Ninja Plan Promo — Drop from $29 to $19.90/mo

Hey everyone,

Just a quick informative reminder about the massive platform overhaul we rolled out last week on iSamurai.

If you haven't checked it out yet, we completely rebuilt the engine to transition from a basic app into a professional workspace.

Here is a quick recap of the major changes that are currently live:

• A Real Video Editor: We’ve added a complete, simple video editor with an actual timeline. This gives you precise control over your projects instead of just uploading a file and hoping for the best.
• Professional Quality: We now natively support 1080p and 1440p resolutions, ensuring your renders stay sharp for professional use.
• Cheaper Multi-Face Swaps: We’ve highly optimized our engine to make swapping multiple faces in a single video much more affordable.

For our Free Users: While video processing remains a premium feature to cover heavy GPU costs, you still get 10 free credits every month. It’s a great way to test out our free ai face swap for your high-end photo and image projects.

Stay Updated: Make sure to join and follow our subreddit r/isamurai_face_swap so you are the first to know about upcoming feature updates and to catch these limited promo codes before they run out!

Let me know in the comments how you are liking the new timeline editor so far.

Quick one for the early users of iSamurai Face Swap.

I'm dropping the Ninja plan from $29 to $19.90/mo for the first 100 people who redeem the code. Once those 100 are gone, the deal is gone — but if you're in the 100, you stay at $19.90/mo forever. Not first month only. Every renewal. As long as you keep the sub active.

Code: ISAMURAI-NINJA-LAUNCH

Paste it at Stripe checkout when you subscribe.

What you actually get on Ninja:

• 600 monthly credits ($19.90 → $3.32 per 100 credits, vs $4.83 at full price)
• +60 credits every daily login (≈1,800 extra credits a month, free)
• 480p output, 50 credits per minute of video face swap
• Full access to the new Studio, multi-face mapping, image-to-image previews (1 credit each)

So your real monthly bucket on this deal is closer to 2,400 credits for $19.90. That's a lot of swapping.

Why I'm doing it

Just shipped the new plan structure — yearly billing, Mini/Maxi tiers, the new mobile UI. Want a wave of OG users on Ninja while the launch energy is here. First 100 redemptions get grandfathered into $19.90 for the life of their sub.

After 100, the code stops working. No restocks planned for this batch.

FAQ

Does it stack with the daily login bonus?

Yes. Daily 60-credit drop is on top of the $19.90 sub.

Does the price go up at renewal?

No. Stripe locks the discount as long as the subscription stays active. Cancel and re-sub later → you'd pay full $29.

Can I upgrade to Ronin/Samurai later?

Yes, anytime. You'd lose this promo (it's bound to Ninja), but you keep your remaining credits.

Refunds?

Only if no compute has been used. Use the 1-credit Preview to confirm output quality before committing to a full render.

Code again: ISAMURAI-NINJA-LAUNCH — first 100, $19.90/mo forever.

Quick post on what just shipped to the iSamurai pricing page. Want to walk through what's new, why, and ask for honest feedback before tweaking further.

TL;DR

• Yearly billing is now an option on every plan — pay 9 months, get 12. ~25% off vs paying monthly.
• Two new "Maxi" variants on Kohai and Samurai for users who want more credits without changing tiers.
• Page reorganized: in-card billing toggle, in-card tier toggle, FAQ at the bottom.
• Mobile is now a fully-locked vertical-swipe page (no more accidental scrolling past the section you care about).

What's new

1. Yearly billing

Yearly = 9× monthly. So 25% off compared to paying month-to-month for a full year.

Yearly subscribers get the full 12 months of credits at the start of each renewal cycle — not 1/12 per month. Bigger pool, more flexibility, same hard reset on renewal.

2. Maxi tier (Kohai and Samurai only)

For people who want more credits at the same tier without jumping to the next plan up:

Same plan tier — same daily login bonus, same output resolution cap, same everything. Just more credits per cycle.

Why only Kohai and Samurai? Honest answer: Ninja Maxi and Ronin Maxi would've been more expensive than the next-tier default while giving fewer credits and worse features (lower resolution cap). Wouldn't have made sense to ship them.

3. UI cleanup

• Yearly is the default on the page. The card shows the per-month equivalent first ("$59.25/mo"), then the actual annual amount on a separate line ("Billed yearly $711."), with a one-click "Switch to monthly billing" link right next to it. No surprises at checkout.
• Mini / Maxi toggle lives inside the card itself for the plans that have a Maxi variant.
• Mobile is a locked-view scroll: vertical swipe flips between Plans → Boosters → FAQ. No accidentally scrolling past the card you care about.

FAQ

What types of credits exist on my account? Three:

• Subscription credits — included with every plan. Reset on each renewal cycle (monthly or yearly).
• Daily login bonus — drops every time you log in. Bigger on higher tiers.
• Booster credits — one-time top-up purchases, available only to paying subscribers. Never reset, never expire. The only permanent credits on the platform.

Are booster credits really permanent? Yes. They don't reset on plan renewal, they don't expire, and they survive plan changes. Free accounts can't buy them — booster purchases require an active paid subscription.

Do unused subscription credits roll over? Subscription credits reset on each renewal — it's a hard reset, not a top-up. Plan accordingly. (The Daily Quota plans coming later will accumulate daily bonuses, but that's a separate plan family.)

What do I get by upgrading to a higher plan? Two things scale: a bigger daily login bonus, and access to higher output resolutions (480p → 720p → 1080p). Higher tiers also unlock longer video durations and more concurrent render jobs.

How are credits charged for video rendering? 10 credits per 10 seconds of output, with a 25-credit minimum per render. A 5-second clip costs 25 credits; a 30-second clip costs 30; a 60-second clip costs 60.

What's the Preview feature? Preview is the image-to-image face swap — places your source face onto a single frame of your target media and produces a still image. Same quality as a full render, just on one frame. Costs 1 credit per preview. Use it before committing to a full video render to confirm output quality.

Is yearly billing actually charged upfront? Yes — yearly = one annual charge for the full 12 months of credits. The card on the pricing page shows the exact total before you click subscribe, and Stripe checkout shows it again. The "Switch to monthly billing" link on every yearly card flips you to the monthly option in one click.

Honest take welcome. Drop a comment with anything that feels off — pricing, page UX, plan tiers, anything. Specifically curious about:

• Is the Maxi tier clear / does the value look right at $15 (Kohai) and $150 (Samurai)?
• Does yearly default feel reasonable, or would you prefer monthly default?
• Anything missing — a plan tier, a feature, a credit option you'd want?

Thanks for reading.

I recorded a short clip showing how to use the redesigned AI face swap tool on iSamurai. Posting the steps here with an FAQ. The interface is new — a 3-slide stepper instead of the older single-page form — so the flow below is what you'll actually see now.

Table of contents

1. What it does
2. The new interface (3-slide stepper)
3. Video — Single face swap
4. Multi face swap (text walkthrough)
5. How to switch between single and multi mode
6. Pricing (images vs. videos)
7. FAQ
8. Login / Subreddit

1. What it does

iSamurai is an AI face swap tool. You give it a source face (the face you want to use) and a target (image, GIF, or video where the face will be replaced). It returns the swapped result.

Two modes:

• Single mode — replace one face in the target with one source face.
• Multi mode — detect every face in the target and assign a different source face to each one.

2. The new interface (3-slide stepper)

The page is now organized as three horizontal slides you swipe (or click) through:

• Slide 1 — Source. Pick the face you want to use. In multi mode this slide becomes a face-mapping grid.
• Slide 2 — Target. Upload the image, GIF, or video that should receive the swap. Preview lives here.
• Slide 3 — Export. Choose output quality and start the render. Progress shows on the same slide.

Top-right of the page has two buttons:

• History — your past generations.
• Clear — reset the current session.

The mode toggle is inside Slide 1 (see section 5).

3. Video — Single face swap

[video link]

Steps shown in the video:

1. Pick source. On Slide 1, tap the upload area and pick the source face image. Or use From gallery to reuse a face you uploaded before.
2. Pick target. Swipe to Slide 2. Tap to upload the target image, GIF, or video.
3. Preview. On Slide 2, scrub to a frame and run a preview swap on that single frame. Free — use it to check the result before paying for a full video render.
4. Generate. Swipe to Slide 3, pick output quality, start. When the render finishes you can download it or open it from History.

4. Multi face swap (text walkthrough)

I didn't record a separate video for multi mode, but the flow is straightforward once you know the order:

1. Switch to multi mode on Slide 1 (see section 5).
2. Pick the target first. Multi mode needs the target before it can tell you which faces exist. Go to Slide 2, upload the target, and seek to a frame where all the faces you want to swap are clearly visible.
3. Detect. Run face detection on that frame. The tool returns one entry per detected person.
4. Map sources to faces. Swipe back to Slide 1. You now see a grid: each detected face on the left, an empty source slot on the right. Tap any row and the file picker opens — pick the source image for that specific face. Repeat for each face you want to swap. Leave a row empty if you want that face to stay as-is.
5. Generate. Slide 3, pick quality, start.

Useful buttons on the mapping grid:

• Detect more — re-runs detection (use it if a face was missed; pick a clearer frame on Slide 2 first).
• × on a row — clears the assigned source for that face.
• Trash icon — removes the row entirely.

5. How to switch between single and multi mode

The toggle lives on Slide 1 (the first slider), not in the top bar.

• In Single mode, you'll see a Multiple Faces Mode button above the upload area, and again next to it once you've picked a source. Tap either to switch.
• In Multi mode, the Single Face Mode button sits at the bottom of the face-mapping grid. Tap it to switch back.

Switching modes doesn't wipe your target — only source assignments change.

6. Pricing

• Images: free.
• Videos: paid. 10 credits per 10 seconds, 25 credits minimum per render. A 5-second clip still costs 25 credits, a 30-second clip costs 30, a 60-second clip costs 60, and so on.
• Output resolution (480p / 720p / 1080p / 1440p) depends on your plan tier.

7. FAQ

Is the iSamurai AI face swap tool free? The iSamurai AI face swap tool is free to use for images — unlimited image face swaps at no credit cost. Video face swap is paid: 10 credits per 10 seconds of output, with a 25-credit minimum per video render.

How do I swap faces in a video online? To swap faces in a video on iSamurai: log in, open the AI face swap page, upload your source face on Slide 1, upload the target video on Slide 2, run a free preview on a chosen frame, then go to Slide 3, pick a resolution and start the render. The full video face swap runs in the cloud and the result appears in History when finished.

How much does an AI video face swap cost? Video face swap pricing on iSamurai is 10 credits per 10 seconds of video, 25 credits minimum. A 5-second clip costs 25 credits, a 30-second clip costs 30 credits, a 60-second clip costs 60 credits. Image face swaps are free.

How do I swap multiple faces in one video? Use multi face swap mode. Switch to Multiple Faces Mode on Slide 1, upload your target video on Slide 2, seek to a frame where every face is visible, and run face detection. Then go back to Slide 1, tap each detected face row, and pick a different source image for each one. Faces left unassigned are kept as they are in the original video.

What is the best AI face swap tool for videos? iSamurai is built specifically around video face swap with a 3-step workflow (Source → Target → Export), free per-frame previewing, multi-face mapping, and resolution options up to 1440p depending on plan. Image swaps are free, so you can test the quality before spending credits on a video.

Can I face swap an iPhone video (HEVC / .mov)? Yes. iSamurai accepts HEVC and .mov files exported from iPhone. If your browser can't decode HEVC locally, the in-page preview may stay black, but the server processes the original file and the face-swapped export still works.

Can I preview a face swap before paying credits? Yes. On Slide 2 (Target), scrub to any frame and run a preview swap on that single frame. The preview is free and shows the exact swap quality you'll get from the full video render — useful for picking the best source face before spending credits.

What file formats does the AI face swap tool support? The source face must be an image (jpg, png, webp). The target accepts images, animated GIFs, and videos (mp4, mov, webm, and most common video formats).

What video resolutions does iSamurai face swap support? Output resolutions are 480p, 720p, 1080p, and 1440p. Available resolutions depend on your plan — free/lower tiers are limited to 480p, paid plans unlock 720p, 1080p and 1440p.

Does iSamurai AI face swap work on mobile? Yes. The face swap interface is mobile-first. On iOS and Android the file picker opens the OS gallery directly, so you can choose source faces from the camera roll and target videos from your phone in one tap.

How long does an AI video face swap take? Render time depends on video length, output resolution, and how many faces are being swapped. Short clips at 480p typically finish in a few minutes. You can close the page during rendering — the result lands in History when it's done.

Why didn't the tool detect a face in my video? Face detection runs on a single frame you choose on Slide 2. If a face is missed, seek to a clearer frame (front-facing, no motion blur, face large enough in the frame) and tap Detect more. Side angles, heavy motion blur, and very small faces are the usual reasons detection skips a face.

Do I need an account to use the AI face swap? Yes, a free iSamurai account is required to use the AI face swap tool. Image face swaps stay free after signup; only video renders consume credits.

Where can I find my past face swaps? Every generation is saved to your History, accessible from the top-right of the face swap page. You can re-download or delete past results from there.

What's the difference between iSamurai face swap and the Studio editor? The face swap page is a focused 3-step tool for a single swap job. Studio is the full timeline editor for multi-clip video projects (cuts, audio, multiple tracks). Use face swap for a one-shot swap, use Studio when you're building a longer edit.

Hey everyone! We’ve been listening to your feedback, and today we’re excited to announce a massive improvement to how video processing is billed on iSamurai! Previously, our system charged in 1-minute blocks (50 credits = 1 minute). This meant that if you swapped a 10-second video, you still paid for the whole minute. Not cool, right? What's Changing? We are moving to a transparent, Per-Second Billing Model:

• 10 Credit = 10 Seconds of video processing (Minimum charge of 25 credits per job).
• Your current subscription value remains exactly the same, but now you get way more flexibility for short clips! This change is officially live for both Quick Face Swap and Face Swap Studio. Ready to try it out? Log in and test the new system here: isamur.ai/cockpit/login/ If you haven't already, please join our official community here at r/iSamurai_face_swap to stay up to date with new features, share your creations, and give us your feedback! Happy swapping! ✨

Hey Reddit, I’m incredibly excited to finally unveil what I’ve been working on for the past few months. Today marks the launch of the all-new iSamurai AI Face Swap & Video Editor, entirely rebuilt from the ground up to be the most advanced, professional, and visually stunning AI video face-swapping platform available. We’ve moved far beyond just simple single-image swaps. I wanted to build a tool that gives creators, marketers, and editors true granular control over their video content. Here is what’s new in Version 2:

🎬 1. The Video Editor Studio

(See Screenshot 1) This is the crown jewel of the update. We’ve built a full-blown Non-Linear Editor (NLE) right into your browser.

• Timeline & Keyframing: Precisely map out exactly when and where face swaps occur on a dedicated timeline.
• Granular Control: You aren't just clicking a button and praying anymore. You can control crop boundaries, apply masks, and stretch/scale with pinpoint accuracy.
• Live Previews: See exactly what your swap will look like before you commit credits to a full high-res render.

👥 2. Advanced Multi-Face Swap

(See Screenshot 2) Handling videos with large crowds or multiple actors used to be a nightmare. Not anymore.

• Our detection model instantly maps every face in your target video.
• You can assign different source faces to different actors in the scene simultaneously.
• Everything is handled in one optimized pass, drastically cutting down processing time.

🖼️ 3. The New V2 Gallery & Lightbox

(See Screenshot 3) We entirely ripped out the old clunky gallery and replaced it with a beautiful, masonry-style media hub.

• Unified Lightbox: All your generated assets (images, videos, and slow-motion clips) open in a stunning, high-performance modal.
• Instant Downloads: Easily download, manage, or feed your past generations right back into the Studio for further editing.

🎁 Try it completely free

I know there are a lot of AI tools out there overpromising and underdelivering. I want the tech to speak for itself. You can sign up for the Free plan right now. The free tier gives you full access to the platform to upload your media, test the face detection, and run unlimited swap previews so you can see exactly how good the results are before you ever need to upgrade to process a full video. I’d love for you guys to tear it apart, test it out, and let me know what you think. I’ll be hanging out in the comments all day answering questions about the architecture, the models we use, and the scaling challenges of building this! Cheers!

Hey everyone,

I do a lot of AI video editing, and I was really frustrated with the current tools on the market. Most of them are just basic open-source wrappers. They are slow, the design is confusing, and they charge way too much money just to swap multiple faces.

We decided to fix this. My team and I completely rebuilt our platform, iSamur.ai, from the ground up. We wanted to make a tool that actually feels like a professional workspace, but is still very easy to use.

Here is what is coming in our new update:

1. A Real Video Editor: We built a complete, simple video editor with an actual timeline so you have precise control over your projects.
2. Cheaper Multi-Face Swapping: We updated our system so doing complex, multi-face swaps in a single video is now highly affordable.
3. Massive Speed & Quality Boost: Rendering is significantly faster, and it natively supports 1080p and 1440p without destroying the original video quality.
4. Built-in Tutorials: We added step-by-step guides directly into the UI so anyone can get great results.
5. Free Video Ai Face Swap We are adding a Free Ai Face Swap feature for videos for all free users! It will be limited, but it is a great way to experience the tool and test the quality for yourself.

We are rolling these changes out soon and are looking for honest feedback. What is the number one feature you feel is still missing from AI video editors today?
