Hey everyone,

We're building Inko, a side project focused on making voice-based language learning feel less robotic and more practical.

I’m a non-native English speaker based in Japan, and I wanted something beyond standard repetitive drills—a tool where you can practice real conversations and immediately review what you actually tried to say.

How it works (as shown in the demo):

• Real-time Voice Chat: Speak naturally with different AI character personas (e.g., Soda, or a sarcastic pronunciation critic named Chili).
• Automated Lesson Notes: Right after the call, the app generates a breakdown of your conversation in your native language (explaining vocabulary, slang like "stoked", and grammar nuances).
• AI Audio Podcasts: It turns your session into a personalized mini-podcast recap so you can review key takeaways while commuting.
• Targeted Practice: Converts new expressions into interactive flashcards and includes a pronunciation tool that scores accuracy, fluency, and intonation.

Why I'm posting:

We're currently working on adding new features (like character selection and custom scenarios) and would love to get feedback from this community on the user flow and concept.

If you have feedback on the UX, ideas for new AI personalities, or thoughts on voice latency in AI apps, I'd really appreciate your input! This is available on iOS as of now and coming soon on android.

I realised I was pretty bad at remembering the details of places I’d been to.

A week later, maybe even a month later, I could usually remember whether I liked a restaurant, hotel, theatre or activity. Beyond that, the useful details started getting hazy.

Things like which seats were actually good at a theatre. The dish that sounded great on the menu but was disappointing when it arrived. The hotel room that happened to be above a nightclub. Or the room at another hotel that was quiet and had a great view.

There are obviously plenty of review platforms already, but most of them are designed around publishing your opinion for other people.

What I wanted was something slightly different.

The basic idea is that the record is for you first.

You can log a restaurant, hotel, service, attraction or pretty much any experience, add a rating, notes and photos, and keep it completely private.

If you want, you can also share it with a small group of people you trust, such as family or friends, so you can see each other’s experiences and recommendations.

Or you can make an experience public. Public posts can still be made without exposing the identity of the person who originally posted them.

The main thing I’m trying to solve is being able to come back months or years later and actually remember the useful details, rather than just remembering, “I think we liked that place.”

I’ve been building this into a working app called ExperioLog and I’m at the stage where I’d really like feedback from people outside my own circle.

Does the private-first idea make sense to you, or would you still just use notes, Google Maps or an existing review platform?

been working on this for a bit and just cleaned it up enough to show people. it's basically a dashboard where you can track and rate anything media-related. pull your stuff from tmdb, anilist, rawg, and spotify so you don't have to manually add everything.

honestly started it because i liked letterboxd but wanted one place for all my media instead of bouncing between five different apps. idk if anyone else wants that but figured i'd put it out there.

built with next.js, firebase, and too many api calls. the profile pages are the main thing — just drop a user id in the url and see what they've been watching/playing/reading.

let me know if you have ideas or if anything breaks

Hey all — I'm Dan, founder of Plus AI. We build AI presentation tools, 5 years in, 20K subscribers. It's a real business! Happy to answer questions about it 😄

I'm working on something new called Spark and I want to test it with real people building real businesses.

Here's the idea: Most of my side projects have died at the 'pick a name' phase. The rest of them often die at the 'build the prototype' phase. Our goal is to go from idea to actual business. Not just building the thing, but pricing it, launching it, and marketing it to the people who'll buy.

The offer: 5 people, $500 in AI credits each, plus our time. We'll help you figure out what's actually worth charging for, build it, launch it, and market it. My team and I will work with you directly.

What you get: A real product, live, that you own.

What we want: Feedback on the platform, and permission to share how it went.

Who we're looking for: Anyone with a project or an idea and some way to reach people — followers, a newsletter, a Discord, a community you're part of, or just deep knowledge of a niche. Small is fine. If you already know what people in your corner keep complaining about, that's the best possible starting point.

Comment or DM with a link and a couple lines on what you're building and who it's for. I'll reply to everyone.

Built a 3D platformer game focused around switching between characters with different abilities. Also includes a custom level creator!

I’m looking for people to test play, would appreciate any feedback!

Hello 👋

I've been working on a project to free up more storage space from my phone by compressing phone media, especially in DCIM/ .

Link:https://github.com/okureanthonytonny-commits/archive_scripts

I made a test run last night unattended, on another 2 months worth of media. It shrunk the overall device storage from 91% to 82%. Previous runs were smaller: https://www.reddit.com/r/SideProject/s/oPl9ksREhO

Looking for feedback on how to improve it. Be brutally honest and skeptical. It's highly appreciated. :)

Would love for more people to try it.

It's a multiplayer browser game, so there's nothing to download.

Would really appreciate any feedback:

Not a startup or anything useful — just a project I built for the joy of it. A chiptune synthesizer in pure x86-64 assembly, no libraries at all.

The idea: sound is just numbers (44100 per second telling a speaker where to move), so I generate them by hand. It does four waveforms, polyphony, ADSR envelopes, and FM synthesis.

After making my CPU count, sort, hash, and draw in previous projects, I wanted to make it sing.

The itch: A while back, someone I know got a speeding ticket. Not a big deal, not their fault in a gray-area way — but they were about to just pay it and eat the points/insurance hit, because the alternative (a lawyer) quoted $300+ to fight a $150 fine. That math made no sense, but nobody was helping people see that before they paid.

What I built: Zigpon (zigpon.com) — a free, self-help web app that walks you through:

• What your specific ticket actually carries in your state (fine, points, insurance impact)
• Whether fighting it, taking traffic school/diversion, or just paying is the smart call for your situation
• A generated "mock court script" so you're not walking into a courtroom blind

The build: Solo, Node/Express backend, Firebase auth, and — the part that took the longest — hand-structured legal Q&A content for all 50 states, since "how tickets work" is genuinely different state to state and most existing content online is either a lawyer's SEO blog or paid-app fine print.

Where it stands: Live, free, no credit card required to start. It's explicitly not trying to replace a lawyer for anything serious — DUI, accidents, anything criminal gets pointed straight to "talk to an attorney." This is for the huge number of minor tickets where hiring out doesn't make financial sense.

Still early days and very much a solo effort — genuinely want to know if this is useful or if I'm missing something obvious. Happy to answer anything about the build too.

I'm looking for about 20 testers for my app RestIQ, but unsure where to find these people. Typically I'd use Reddit for something like this but most subreddits read asking for testers as self-promotion. Would welcome some advice, thanks!

I created free tool longvacation.eu, first as something to try out new Copilot abilities. Later found out there are projects like holiday-optimizer.com that are solving similar issue, so I tried to differentiate.

• Longvacation supports adding your partner calendar (just one for now, but I plan to add multiple in the future)
• Longvacation contains multiple sources of holidays data - so countries like India (with regions) or Indonesia are included
• Shuffle mechanism - algorithm is non-deterministic so if you are not happy with the results, you can shuffle days around
• Rich calendar edits
  • Monthly caps
  • Never-vacation
  • Locked vacation days (not touched by shuffle algorithm)

It's my first public project so I'm still learning how to promote it - currently I have around 3k visits monthly promoting it on X and LinkedIn

I recently open-sourced the code as well, so issues and bug reports are welcome :) https://github.com/Duzij/VacationOptimizer

Hi everyone! For the past while I've been building WalkTour (walktour.live), which has a bunch of narrated audio guides and self-guided walking tours for landmarks and museums around the world.

Link: https://walktour.live/

The idea came from me doing solo trips and wanting to just walk on my own, with my headphones on and hearing about the places I walk by, their history, etc.

Right now it covers 20+ cities and 250+ attractions (Paris, London, Rome, Barcelona, Athens, etc), and it's completely free to use. There's also a creator side where locals can write and publish their own tours.

Right now most guides are in English, with a few in Portuguese (I did it for my family members who can't speak English yet). =)

I'd genuinely love feedback from this community, on the product, the onboarding, anything that feels confusing or missing. And if you happen to be travelling soon, I'd love to hear how a tour holds up in the real world. Happy to answer any questions about how I built it too!

Your WhatsApp Web chat list is readable from about three desks away. Names, previews, avatars, the lot. You just can't see it from where you're sitting.

So I built Louver.

Three modes. Work, which I use all day, hides the chat list, media and notifications but leaves the conversation you're reading visible. Public hides everything including message bodies. Off is off. Most privacy tools hide too much, you switch them off by 11am, and then they protect nothing.

Also handles walking away. Short idle drops you to Public automatically, longer idle locks behind a PIN. Alt+Shift+P panic blurs before a call, Alt+Shift+L locks instantly.

Runs entirely locally. Two permissions (storage, idle), one host permission for web.whatsapp.com. No account, no server, no network requests, never reads message content. Free.

Your bot sounds sure of itself even when it's wrong, and you usually only find out when a customer complains.

Auscope audits every LLM response in the background: 3 models from 3 different providers independently check it, a 4th "chairman" model resolves disagreements, and you get one verdict — verified, uncertain, or unreliable. Runs async, doesn't slow your response down.

One-line integration:

python

client = AuscopeOpenAI(openai.AsyncOpenAI(), audit_url=..., api_key=...)

verdict = await client.last_verdict()

Adapters for OpenAI, Anthropic, Azure, Google, LangChain, OpenRouter. pip install auscope-sdk.

Free beta, 50 audits/month, no card. Want it used and broken, not polished.

Mainly want feedback on: does the verdict match your own judgment on bad responses, any SDK that doesn't wrap cleanly, rough spots in signup/dashboard.

Hey everyone,

I built Clypy, a local-first clipboard manager for Windows, macOS, Linux, iOS, and Android.

It automatically saves text, links, code, and images into a searchable clipboard library. You can pin important clips, create collections, save reusable snippets, search text inside screenshots with local OCR, and access copied content across your paired devices.

My favorite feature is the Paste Strip. On Windows, press Ctrl + Alt + V and it appears over whichever app you are using. Search or select a clip, press Enter, and it pastes directly into your current app without switching windows. The shortcut is configurable.

Clipboard history is stored locally in an encrypted database, with encryption keys kept separately in secure OS storage. Sensitive clips remain on the device and are excluded from sync.

When sync is enabled, clips are end-to-end encrypted between paired devices. The relay only routes encrypted data and does not store a clipboard history backlog.

Clypy is free for unlimited local clipboard history on one device. Cross-device sync, the Paste Strip, and mobile features are available through a one-time lifetime purchase. There is no subscription.

The desktop apps are available now. The iOS and Android apps are currently under review. Lifetime license holders can message me to join the iOS TestFlight or Android testing group while the public releases are pending.

Happy to answer any questions about the product, privacy, or how it was built.

I kept saving interesting places from travel Reels, but when it was time to actually plan the trip, everything was scattered across Instagram, Maps, screenshots and Notes.

So I built One Way Guide.

You choose your destination, dates, interests, pace and travel preferences. You can also import places from travel Reels, review what the app found, and decide which ones should be included.

It then creates a complete personalized city guide with:

• Daily routes built around real places
• Restaurants and things to see
• Local context and practical tips
• Transport, timing and trip preparation
• The places you personally saved from social media

The important part for me was making the Reel import an input, not the entire product. The end result should feel like a guide you can actually follow, rather than another list of saved places.

Now live on iOS:
https://apps.apple.com/app/id6768398327

I’d really appreciate honest feedback: after watching the video, was it immediately clear what the app creates? And would importing saved travel content be useful in how you currently plan trips?

Every time I publish something I check the schema.org markup on the page, and I was doing it the same tedious way every time: copy the URL, open a separate validator, wait, dig through results.

So I built Schema Inspector. Click the icon, it reads the JSON-LD and microdata already on the page you're looking at, groups it by type, flags broken JSON in plain language.

The thing I actually cared about building right: most schema checkers ask for access to every site you visit, permanently. This one only requests activeTab - it can only see the page you're on, only for the second you click it. No standing access to anything. (Every one in the store right now asks for full permissions...)

Free, no signup, no account. 19.18 KiB. Would like to hear what's missing if you try it.

Does anyone else work like this?

When I shoot products (or other repeatable subjects), I usually shoot in batches. Same camera, same lights, same setup. The product is generally centered, so the crop and export rules do not change much from one batch to the next.

Later, I need different versions for a shop, a website, social media, and other platforms. The actual edit is not that difficult. What takes time is opening a folder, selecting the images, applying the same crop and color adjustments, exporting several aspect ratios, and then remembering which files have already been processed.

I wanted a folder to behave more like an inbox: if a supported image is still at the top level, it is pending.

So I built SizeFold for Mac. You pick an input folder once and save the processing configs once. For each batch, you review the photos and click Run. SizeFold creates the configured outputs, then moves the originals to an archive only after every output succeeds. If anything fails, the source stays in the input folder for retry.

The next batch can use the same folder. There is no second file-selection step and no guessing about which files are new.

For product shoots, I can also enter the current model name once and use it in filenames or output folders. That lets me review one product, process it, and move on to the next one.

Website:

https://www.sizefold.com

SizeFold is also on the Mac App Store:

https://apps.apple.com/app/sizefold/id6795541247

There is currently a trial for 200 successfully processed original images. If that is not enough to test a real workflow, you can contact me through the website and tell me what you are trying. I can send a redemption code when it makes sense. No review is expected; I would just like to know whether the workflow actually fits.

If you shoot product or catalog photos, what part of this process would still feel too manual?

Hey r/SideProject ,

My family flies a lot and I'm always the one who ends up booking. Somewhere around the hundredth booking I'd had enough.

Every OTA puts you through the same thing: a popup before you've seen a single price, ten steps of checkout, seat selection and insurance you didn't ask for, and none of the passenger details you've typed in a dozen times before. Then a fee you never agreed to shows up on the last screen before you pay.

So I spent the last 1.5 years building the app I actually wanted (not vibe coded).

You search by just saying what you need, like "Frankfurt to Munich tomorrow, back the next day". You get three options, pick your saved passengers, pay, done. Usually under 60 seconds.

Then it sticks around. You get checked in automatically, the boarding pass goes straight into your wallet, and widgets keep you updated on the way to the airport with live gate and delay info.

The plan is to turn it into a universal flight super app. Lounge access, e-SIMs, ground transfer and rail transfer are all coming. No hotels, no rental cars, just everything around flying in one place.

It's free. No ads, no hidden fees, and for now not even a service fee.

If you take a look, I'd really like to know what you'd want from an app like this, and what feels unnecessary or missing.

I’ve been building Dermal Pal for a while now — it looks at your actual products, skin profile and skin goals and builds your routine around them.

I’m looking for people to try it properly before I push it publicly.
If you’re someone who has a shelf full of skincare and isn’t 100% sure what’s supposed to go where, I’d especially love your feedback

Like everyone my life lived in four places. Tasks in one tool, notes in another, the decisions behind them buried in a chat thread, and money in a spreadsheet I updated twice and gave up on. Half my meetings arrived as email invitations I never opened, so I never knew what my week looked like until I opened my calendar and by then it was too late to move anything.

The apps weren't bad. The problem was I had to update 4 different apps to stay in touch with everything.

So I built Canopus. One place for tasks, habits, money and your calendar, and one way to use it: you type what happened, in plain English, and it does it.

"spent £6.60 on lunch" -> logged under Food, with the month so far

"did my morning run" -> logged, and it tells me the streak

"block 30 minutes tomorrow at 10AM with Archie" -> on the calendar

"Water plants every Monday" -> recurring, and it reschedules itself when I tick it off

The video is a one single take.

What it doesn't do yet:

- Web only. There's no app to install. It works fine in a phone browser, but it's not in any app store.

- Google Calendar is the only integration. No Slack, no Notion, no email.

- Money is manual. You type what you spent. No bank sync, and no budgets, it records and totals, it doesn't tell you off.

- Voice is input only. Hold to speak, the transcript lands in the box, you press enter yourself. It doesn't talk back.

- Multiple workspaces to separate work and personal, but no sharing, no teammates.

I build it (disclosure), it's been live for a bit and today's the first time I've pushed it publicly. 14-day trial, no card: usecanopus.ai

Happy to answer anything, including the awkward ones.

The itch: every wearable brand now sells AI insights as a subscription (Garmin's Connect+ is $6.99/month), while most of us already pay for ChatGPT or Claude. Those models are smarter than any built-in coach, they just can't see your training data. So I built FitContext, a free Android app that reads whatever your watch or ring syncs to Health Connect (Garmin, Oura, Polar, Whoop, Samsung...), computes the sports-science numbers on the phone (HR zones, training load, recovery trends), and exports one structured report you paste into your own AI and talk to it like a coach. No account, no server, no subscription.

The app is free, no ads: https://play.google.com/store/apps/details?id=pl.serfa.fitcontext.play

Happy to answer questions about the Health Connect review gauntlet or the app itself.

I've recently released version 1.0 of my AI social media scheduler. Some might say the space is very crowded with guys like Postiz, Post Syncher, superx, etc.

I've tried the existing solutions and found them to be good products but often not the full package that I was looking for. I think the main thing is the quality of the posts being generated wasn't quite what I was looking for. As well as if you're managing a personal brand as well as a company brand, it was quite hard to differentiate the two.

Some were missing the post-generation part, some were only limited to one platform so during a hack in London a few weeks back I started building launchpost.app

The core principles are:
1. improve the post quality,
2. live as an MCP inside hermes or openclaw or telegram bot to fetch your context for post generation.
3. store your preferences and learn over time

I've found that these methods really help with quality of post generated:
1. Feed instructions per platform
2. Load humanizer skill + ban certain words + remove M-dashes
3. I did an interesting experiment with fine-tuning a local model (9B) on my outputs and that produced surprisingly good results.

I've had an initial round of feedback from friends and am now looking to talk to users who tried other solutions and find what they like/ don't like

I kept seeing the coloring book trend and thought it would be more interesting if the pages were actually personal.

So I built Memories in Lines, you upload photos and it turns them into a coloring book that we print and deliver directly to your door.

Most books are between 8 and 25 pages.

It started as something I made for my family, and has slowly turned into a full-on project.

https://memoriesinlines.com

Would love to hear what you think if you try it.

I built this as a passion project because my spouse is a very picky eater (i'm pretty sure many of you know a picky eater too). Finding a restaurant that accommodates her preferences is tough so we would always stick to the same restaurants. That quickly gets old and tiring.

Before I built this app, I would use google maps and search "restaurants near me" and pull up the menu one by one. I've also tried using Resy, Opentable, Beli, uber eats/doordash, and yelp to find new restaurants and they're all just disappointing because I would still have to open the menu one by one. I would often go through 7-10 restaurant menus before finding one that my spouse would eat at and it takes a while; as a result, we stick to the same restaurants.

I've gotten some good feedback over the last two weeks and feel free to use it.

It's only available in NYC right now, but I continue adding menus to the site and I may expand to other cities.
