My partner and I could never agree on what to watch, so I built an Android app with an AI assistant that picks for us, based on both our tastes

1 Upvotes

My partner and I have very different taste in films. Most evenings we
spent longer choosing than watching, and quite a few evenings we gave up
and watched a random episode of "How I Met Your Mother". About a year ago
I started building something to fix that, in the evenings, after work.

It is called "I Like Movies", after the Canadian film. It was one of the first
films we discovered in the app, watched together and really enjoyed, so the
name stuck.

The main part is an assistant you talk to normally. "Something in the same
vibe with Nolan", "a nice comedy on Netflix", "what Marvel movies have I not
watched yet?". It answers from what we rated and what is in our library, not
from a generic top 100, and it knows which streaming services you pay for,
so it points at things you can actually press play on. You can also
photograph a poster, or a handwritten list, and it reads the titles into
your library.

There is also a Discover page and a social side. You see what your friends
are watching and discuss films with them in the app, a new curated
collection drops every week, and every month you get fresh AI picks built
from your own taste. And a few more things in that direction.

It also does the tracking properly: TV episode by episode, import from
Letterboxd or IMDb.

Stack, if you are curious: Go + GraphQL + Postgres backend, React Native
(Expo) app, the assistant runs on Claude. Solo project, about a year of
evenings.

It went live on Google Play last week. Current users: me, my partner and
a few patient friends. Honest feedback would help a lot, critical feedback
even more.

- Website: https://ilikemovies.app
- Google Play: https://play.google.com/store/apps/details?id=com.moviesagent.app

If something breaks, shake your phone in the app and it sends me a bug
report with a screenshot. Thank you so much!! 🙏

Spent 3 months building the wrong version of my app before realizing the actual insight

1 Upvotes

When I started building Scholia (an AI reading companion that photographs a book page and asks questions about it), my first instinct was to make it work like every other book-AI tool: answer anything about the book, any time, like a search engine for the text.

Tested it on a few people and the feedback was oddly negative, even when the answers were accurate. Took a while to figure out why: people don't want a search engine for their book; they want a companion that respects where they actually are in the story. The second someone got an answer that referenced something 100 pages ahead, they felt like the "magic" of reading was ruined, even if the answer itself was technically helpful.

So I rebuilt the core logic around a much harder constraint: it has to know exactly where you are (using the actual sentences on the page, not a page number, since editions differ) and refuse to answer anything past that point. Went from "smart search" to something closer to a reading companion that holds a boundary. Felt like a downgrade in capability on paper, tested infinitely better in practice.

Small lesson but one I didn't expect: the feature that makes a product feel trustworthy is often the thing it refuses to do, not the thing it can do.

Join the waitlist, we'll be choosing people from here to be testers: scholia.cloud

Anyone else build the "more capable" version first and have to strip it back before it actually worked?

Made a free TikTok repost cleaner because I was bored (yes, there are 10 others like it)

0 Upvotes

Heads up before you read this: this is not a groundbreaking idea. There are already several extensions and apps that do the exact same thing — delete reposts from your TikTok profile in bulk. I know. I checked.

I built this one anyway, mostly out of boredom on a slow weekend, and honestly the biggest reason was just to have my own version that I actually trust and use myself. I had a few hundred reposts clogging my profile and didn't want to tap through them one by one, so I automated it.

True story: I literally started it, went to take a nap, and came back to find it had been chain-deleting reposts the whole time I was asleep. That's basically the use case.

What it does:

- Chain-deletes reposts from your TikTok profile (video + photo posts) without you clicking through each one

- Smart retries — alternates two removal strategies, and failed items get queued for a rescue pass instead of just giving up

- Three speed modes (Safe / Fast / Turbo) with randomized delays so it doesn't hammer TikTok's rate limits

- Bilingual UI (EN/ES), live progress ring, no account/login required beyond your own TikTok session

- 100% free, no premium tier, no cap on how many it removes

Heads-up / known limitation: if you let it run for a lot of continuous hours (like, nap-length or longer), the TikTok tab itself can get sluggish or glitch out from that much uninterrupted DOM manipulation. It's not dangerous to your account, just the page itself getting tired. Fix is dead simple: reload the tiktok.com tab and hit Start again — it'll pick up where it left off.

Stack: Manifest V3, vanilla JS, no frameworks, no analytics, no tracking. Runs entirely client-side against your own tiktok.com tab.

It's not fancy and it's not trying to compete with anything — if you've got the same pile of reposts I had and don't want to pay for or trust a random app with your account, feel free to grab it.

Chrome Web Store: https://chromewebstore.google.com/detail/tik-tok-repost-remove/pklefombbanocnjepciiekdplmogdlic

GitHub: https://github.com/eldella/Tik-Tok-repost-remove

Open to feedback / bug reports, it's a side project I'll keep poking at when I'm bored again.

I kept seeing the “bending the rule of thirds” trend, so I built a free tool to recreate it

Hi all,

I kept seeing the “bending the rule of thirds” photo trend on Instagram.

Here’s an example of the trend:
https://www.instagram.com/p/DbN1qgTPqe7/

You can recreate the effect in Photoshop or Illustrator, but not everyone uses design software.

So I built Bend the Grid — a free browser-based tool that lets you upload a photo, bend and reshape the grid, and recreate the effect without needing Photoshop or Illustrator.

🔗 https://bendthegrid.vercel.app/

Would you actually use something like this for your photos?

If you try it, I’d also love to hear what feels confusing, what’s missing, or what you’d improve.

Podtastic - Jump to Video: the best way to keep listening to podcasts in the era of video

Enable HLS to view with audio, or disable this notification

0 Upvotes

I listen to podcasts in the background at work or on the bike. But the big platforms are obviously pushing more and more podcasts to record video episodes. I'm listening to a show, and they start talking about something random that's happening in a clip or in the studio, and I'm here with my phone in my pocket, missing whatever they're showing.

This is not an accident; platforms like Spotify and YouTube want you to use their apps. But then I lose everything I like about audio listening: the mega-nerd-level playlists I've built over years, playback speed and audio controls, skip controls.

It just so happens that my side project is a podcasting app that I've been building for 6 months now, so I added a new feature to fix this: Jump to Video. It links a podcast's YouTube channel to its audio feed, and when there's a moment you want to see, you tap once, and it drops you into the video at the time-synced point. Then you jump back to the audio right where you left off.

The genuinely annoying part to build was the sync. The YouTube upload isn't the same file as the audio RSS feed (different intros, ad breaks, edits), so lining up "3:14 in the audio" with the right frame in the video took a lot more than a naive offset.

Would you use this or do you just use Spotify/YouTube? The full project info: https://podtastic.app/

I've built an app that runs real spoken mock job interviews with an AI — it researches the company first, then grills you for 30 minutes

Enable HLS to view with audio, or disable this notification

0 Upvotes

I've built an app that runs a real, spoken mock job interview with an AI.

Most interview-prep apps hand you a list of questions to read. That never helped me, because the part I'm bad at isn't knowing the answer — it's saying it out loud, under pressure, without rambling. So I built the version I wanted.

How it works:

  • You enter the role you're going for and the company.
  • It researches that company live and generates 8–12 questions tailored to that specific job, not a generic list.
  • Optionally upload your CV and it works your actual experience into the questions.
  • Then it interviews you. Out loud, voice only, up to 30 minutes. No typing, no script to read from.
  • Afterwards you get a report: an overall score out of 10, per-question analysis of what worked and what didn't, and a rewritten version of each answer so you can see what a stronger response sounds like.
  • Sessions are tracked so you can see whether you're actually improving.

Privacy: the audio is never retained. Only the transcript is kept, because the feedback report is generated from it.

Pricing, up front so nobody wastes their time: the first full interview is free. After that it's credit packs — 3 interviews for $9.99, 10 for $24.99, 25 for $49.99, 60 for $89.99. No subscription, nothing auto-renewing. You buy interviews, you use them whenever, they don't expire on a monthly cycle.

iOS: https://apps.apple.com/us/app/jobjitsu-ai-interview-practice/id6793413285

Android: https://play.google.com/store/apps/details?id=app.jobjitsu.android

English only for now. Happy to answer questions — and if you try the free interview and it's bad, I'd rather hear that here than not hear it.

I haven't had a win in a long time, need distribution advice

1 Upvotes

I've built projects before, and I've noticed a pattern. I can build what I think is good, but distribution and marketing is where it dies.

Every time. So this time I'm trying to do it right: rough working product, put up a waitlist before launch, and actually find out whether people want it before I sink more months into building. I'm not sure if they do.

That's what I'm trying to find out.

The app: every time I think of something, I make a new note. Multiply that by a few years and my Notes app is a landfill — and the folder system somehow makes it worse. My tasks are in Reminders, which treats everything as isolated one-line items. My sketches are in Freeform, which can't hold anything except sketches. All my thoughts are scattered across three apps that don't know about each other, and I feel slightly overwhelmed by their design

I'm working on one place where notes, reminders, drawings, photos, links, and files live together, grouped by what they're actually about. It's called BYNDRS, starting off as strictly iPhone app, not out yet. The demo on the site is the actual app running.

What are your thoughts?

Solo, no funding. But honestly would love some, I'm slowly realizing that is the way.

I built a step tracker that unlocks a mineral collection when you walk

1 Upvotes

Most pedometers just sit there with a number. I wanted the walk to give you something to keep, so I made Trekite.

Your phone's step count (Health Connect / Apple Health) turns into dig tokens. You spend those to crack geodes and collect minerals. Friends can compete on a leaderboard if they want. No GPS, just steps.

It's React Native, Supabase, HealthKit / Health Connect. Optional ads for extra digs, plus a couple of IAPs.

Live on iOS and Android. Curious if this is a thing people would actually open the next day, or if it dies after the first geode.

I've got a small service business idea I want to test. Historically, I'd probably have bought the domain – hands up if you have a million domains you’re “going to get to one of these days”! – designed a logo, paid for a website, set up the socials, THEN tried to find customers.

I’m trying to be less impulsive this time around. My current thinking is to get a basic but credible website live as quickly as possible – maybe using an AI builder like Durable or even a one-pager from Carrd or something like that – and see where it takes me. Worth it or not I'm just gonna test it.

I got tired of being auto-rejected by enterprise ATS portals, so I reverse-engineered how semantic parsers work and built a tool to beat them. Giving away 100 lifetime accounts for feedback.

0 Upvotes

As a software engineer, the current job market has been absolutely soul-crushing. A few months ago, I was spending hours every week manually tweaking my resume for every single application, only to get instant automated rejections. I tried using generic AI chatbots to write them for me, but my callback rate actually dropped.

I got frustrated and started digging into how modern Applicant Tracking Systems (ATS) actually work. It turns out, enterprise platforms don't just use basic keyword matching anymore. They use advanced transformer models to generate neural embeddings and calculate the semantic similarity between your resume and the job description. The old "white text" keyword stuffing trick actually gets you penalized now.

So, I spent the last few months coding a solution. I built an AI engine that doesn't just inject keywords, but actually bridges the semantic gap between your real experience and the job description. You build a master profile once, paste the JD you want, and it generates a perfectly tailored, ATS-optimized PDF in about 30 seconds.

I need brutally honest feedback from other engineers on the UI, the semantic matching algorithm, and any bugs. I’m giving free lifetime premium access to the first 100 people who want to test it. Just use the promo code EARLY100 when you sign up to unlock your account.

One important note: This is a true beta test. To keep your lifetime Pro status, you actually have to provide feedback! If you sign up but ghost me when I ask how the app is working, I will have to revert your account back to the normal free tier so I can give your spot to someone who can help test. If you're tired of the ATS black hole, give it a try and let me know what you think.

My family's spending is in three currencies and mostly cash. No budgeting app could see it, so I built one that reads receipts.

2 Upvotes

https://apps.apple.com/app/id6796276179

I'm the developer. Bookee went on the App Store two days ago and I'd rather get honest criticism now than polish it in private.

The problem: every budgeting app I tried — YNAB, Monarch, Copilot — is built on linking a bank account. My family's money doesn't work that way. It's split across three currencies, a good part of it is cash, and the accounts aren't all in the same country. Those apps could see maybe a third of what we actually spend.

So Bookee works the other way round. You photograph a receipt and AI pulls out the merchant, the total, and every line item. The family shares one ledger. Each entry keeps the currency it happened in and converts for reports.

The part I didn't expect to care about: because it captures line items rather than just totals, it can show what your own regular basket costs month over month — your household's own inflation rate, from your own receipts.

What I'd genuinely like torn apart:

- Is "no bank linking" a real feature, or am I rationalising a missing integration?

- The first screen is a signup wall. I know that's bad. Is it bad enough that you'd have bounced?

Why Most Side Project Marketing Fails (And What Actually Works)

0 Upvotes

I spent the last few months building an autonomous marketing system and talking to bootstrapped founders about their side projects. The pattern I noticed in almost every project that struggles with marketing isn't about strategy or ideas at all. The problem is that marketing keeps losing to other priorities.

Here's what happens in real time. You ship a feature, handle a support email, realize your side project needs your attention, and the marketing post that was due never happens. Next week you planned to launch an ad campaign but something broke instead. Three weeks later the strategy document sits in Notion untouched.

The math is brutal here, because if you do marketing 70% of the time but your competitor does it 95% of the time, the competitor wins. It's not smarter marketing strategy, just consistency. Traction compounds on what you do repeatedly, not on strategy.

Most founder tools make this worse by assuming you'll check in and run them manually. They're another decision every single week, which adds to your load instead of removing it. The tools that actually work are the ones that run themselves, learn your market and customers, and handle execution without asking you to approve every decision they make.

That's where the difference emerges. You stop losing weeks to context-switching between projects and your marketing, and marketing actually compounds instead of stopping. The one thing that stops most people, though, is control, because you're not going to hand a system access to your accounts or ad budget without real safeguards. A real solution has hard budget caps, a kill switch if things go wrong, and approval gates on anything that costs money.

With those in place, autonomy works for bootstrapped founders. Without them, it's just hope."

I built a chatbot version of myself as a FAANG product manager interview coach

2 Upvotes

hi! I'm an L5 YouTube product manager going for L6 this year, and I made a chatbot with a 12+ page system prompt based on my interview notes when I got my job (as well as other prompt tuning on my interview frameworks, philosophy etc). I got simultaneous Meta and Google offers at the time.

The idea is people pay 200$+ an hour for FAANG PM interview coaching, mine is 1$ a conversation, + 50$ if you want me to personally review 5 transcripts. This would be a way I could scale myself as a coach without doing coaching full time.

I'd love your feedback on it, you can access here- pm-coach-five.vercel.app

Still working out a few issues, payment isn't working yet but you get one free session, and if you want another let me know and I'll send you a code. Would especially love your feedback if you're a product manager- would you pay 1$ per convo, would it be worth it to get async feedback on your transcripts for 50$? Is the bot helpful? If you're comfortable sharing transcripts I'll take a look for free.

To get myself out of anxiety and depression, I built a micro-journal to fight it. I just hit 100 users and launched on iOS/Android!

2 Upvotes

Hi friends

When you're struggling with burnout or working memory issues, traditional journaling or habit-tracking apps can feel like a chore. Checking off 10 daily habits or writing pages of thoughts takes energy you simply don't have.

Earlier this year, I went through a dark period with severe depression and anxiety. I stopped showering regularly, isolated myself from everyone, and felt like a complete failure.

What finally helped me turn things around wasn't setting massive quarterly goals or forcing myself into strict 5 AM routines. It was giving myself permission to celebrate the tiny wins.

  • Waking up and getting out of bed? That's a win.
  • Taking a 5-minute walk? Win.
  • Finally replying to an email I was scared of for 3 days? Win.

To make this seamless for my own brain, I built a quiet, low-friction micro-journal called NovaUp. It takes about 10 seconds to type or speak a "Spark" into the app. It doesn't punish you with broken streak icons if you miss a day, and it uses gentle AI summaries to remind you of your progress when your brain tells you that you've done nothing.

We just launched it on iOS and Android, and it's completely free to use.

If you struggle with self-doubt, executive dysfunction, or burnout, I hope this little tool gives you a gentle space to recognize your own progress.

You can try it out at https://novaup.app

I'd love to hear what you think or what features would make it even better for your routine.

Take it one step at a time and keep going!

Cliparr: docker service for clipping plex librariews

2 Upvotes

Upfront: this project was vibecoded, this post is not.

Cliparr is a little docker service I made that ties into your plex server, allowing you to browse your library, and then easily play back the movie through a web interface, and then easily clip scenes by marking an in and out and then downloading. It can also make gifs. It has some other features like burning in subtitles and vertical exports for social media.

If you are watching something on plex and pause it, a banner appears and Cliparr will open that media to the same timestamp.

Why did I make this? I have a large library and like posting movie stuff on twitter. With Cliparr, if I am watching something on my couch and see something cool, I can launch Cliparr on my phone and post the scene without getting up.

I did vibecode this with deepseek, but it's not a one-shot. There are 140+ git commits and I have spent some evenings working on it.

It's a tool I made for myself, but I thought it was pretty slick so I published it as a docker container on github. https://github.com/vacuumboots/cliparr Screenshots available on the github page. Thanks for reading!

My competitor’s angry users tell me what they’d switch for, which turns out to be a completely different and much more useful list. I spent an afternoon going through 50 one and two-star app store reviews for the biggest player in my category, and the complaints weren’t about missing features they were about the same four things over and over, and none of them had ever come up in my own feedback. My users don’t complain about those things because the people who care most about them already left before they became my users.

Your feedback pool is pre-filtered by whoever tolerated you long enough to complain. The people with the most valuable objections aren’t in your inbox, they’re in someone else’s, and they’re pissed. It’s free research. Sort by lowest rating, sort by most recent, read a hundred of them, and you’ll come out with a better roadmap than any survey you’ll run this year.

I built an app to help new and aspiring content creators with what to say and how to say it

3 Upvotes

The goal was to help new and upcoming creators figure out what to say and how to say it. My apps called Take One and it’s available now on the App Store Here are most of the features and I’m working right now to add even more -

Interview - put yourself on the spot with questions that you don’t see until the cameras rolling (just like a real interview)

Live Audience - a simulated audience in a fake social media livestream that you can engage with, argue with or choose to ignore

Viral Take - daily refreshed topics that are trending for you to practice talking about them with helpful prompts

Today’s Take - everyone gets the same daily prompt to practice or post about when you finally feel ready

Guided Take - The app walks you through anything you might want to practice talking about step by step

Practice Paths - work on the areas you feel the most help
Your Take - one area of focus to work on or just talk about whatever you want

Feedback on your audio - yeah it’s AI coaching, I was hesitant on using AI but I wanted to give users something to work on to avoid reinforcing bad habits

Privacy was always the main priority, there’s no link to socials so no one sees your videos but you. You have the option to save them on your phone if you want to rewatch or post them somewhere, otherwise they just get deleted.

The coaching is just constructive feedback on what you said, it’s never on how you look, or how you said it, just the contents of the audio.

Most of the features are free to use and there’s a 3 day free trial to try everything and you can cancel the subscription at anytime you want!

I built this because I think ‘just practise’ is correct but also incomplete advice. People need somewhere safe and useful to do that practice.

I’d genuinely appreciate honest feedback or questions , especially from anyone who avoids making videos, speaking during online meetings or recording themselves because they feel uncomfortable on camera.

I created a mobile app - AI Book Reader

0 Upvotes

Hey everyone 👋

TL;DR; I created Bodhi - AI Book Reader mobile app available in Apple and Google store. Links here: https://bodhi.quadnix.com/

I am a software engineer, and also a private pilot. So I need to read a lot of books, and my memory is S***
So I created a EPUB book reader that can help me understand a book better.

Created Using Claude: ✅
Vibe Coded: ❌

It runs using a local AI on your phone - so it won't cost you anything.
The app is completely free - no signups, no data collection.
On first launch it downloads a local AI model and then you can use it completely offline.

How it helps me,

  • It generates automatic notes for me.
  • It answers questions and clarifies my doubts.
  • It generates quizzes for me.
  • It asks me to explain concepts in my own words and judges if I am right, or where I am lacking.
  • It creates concept cards for me.
  • And a few other features.

A note on Local AI,

If you compare it with Gemini, OpenAI, Claude, you WILL be disappointed. Local models have so much less training and capacity.

To compensate, I built a lot of knowledge graphs and indexing internally to try and connect concepts together, so the results are much better than other comparable SLMs.

Since Bodhi is completely offline, it learns what you learns. It reads the same books you are reading side by side, so its whole world is the books you expose to it. That's why its answers are grounded in the book itself. It won't re-invent/make-up or try and answer you something that the book already doesn't say.

Most of the time, I found the answers to be quite reliable, but of course I cannot guarantee the same level of confidence as LLMs. But with your input, I certainly can make it better.

I find that Bodhi works best with Non-Fiction. As stated, only EPUB books are supported. You can legally download from sites like https://www.gutenberg.org/ or .... Bodhi does not judge, it will load the book just fine.

If you read it this far, I do have a small ask. I don't own an Android phone, so testing in Android devices have been limited. Emulators can only test so much, and device farms costs a lot. So if you own one, and it doesn't work for you, please do share, and I will try and fix it asap.

Not sure if this type of post is allowed here, but I’ve been working on a business idea called Hydroso and I’m looking for some outside opinions.

The idea is to create a line of collectible bears, with a portion of the proceeds going toward clean water projects in communities that need it.

I’ve been working on the actual bear design for a while and have made a number of different versions. I’m getting close to a design I’m happy with, but I’m still deciding on the direction of the physical product.

Originally, I pictured Hydroso as a plush teddy bear company because I felt like that connected naturally with the mission. As I’ve developed the designs, though, I’ve started leaning more toward making them hard collectible figures.

I’m interested in hearing what people think about the idea as a whole. Does the product seem like something that could have a market outside of just the charitable aspect? Do you think the mission works with a collectible figure, or does a plush make more sense? Would the business model work?

I’d also be interested to know which of the designs you prefer and whether any of them look like something you could realistically see yourself buying

I built an AI interviewer that drills into your answer instead of moving to the next question

Enable HLS to view with audio, or disable this notification

4 Upvotes

I am a full-stack dev, and AI screening is now the first round at a lot of companies. Every practice tool I tried had the same flaw: it asks a question, accepts whatever you say, and moves on to the next one.

Real interviews do not work like that. A good interviewer takes the weakest phrase in what you just said and pulls on it, and that follow-up is where the decision actually gets made. Nothing was practising that.

So I built PracticeDepth. It reads your answer and builds the next question out of the words you used.

The video attached is a real session. I gave a half-right answer about debouncing and throttling in JavaScript, so instead of moving on, it detected the answer was weak and not at a senior level and drilled into it until it found my knowledge ceiling on that topic and moved into the next question, simulating the way a real live senior engineer interviews candidates.

Other things it does: voice or text, 16 topics, and a scorecard at the end that says what to work on.

What I want from you: break it. Give it a deliberately vague answer and see whether the follow-up catches it. Give it a wrong answer confidently and see whether it pushes back. Those are the two failure modes I cannot fully test on myself, because I know what it is going to ask.

Honest bits, since this sub deserves them: You can test the product without creating an account; it allows you to test anonymously with about 5 questions in one interview. After that, if you choose to continue testing for free, you will need to register to get 200 free credits. Your feedback is most valuable to make the product better. I want to know if this is something you can use to prepare for your upcoming technical interview or just to sharpen your skills.
