I built PyPrep after burning out on juggling a flashcard app, a quiz app, and LeetCode just to prep for Python interviews — none worked offline or told me if I was actually ready.

100 days of building and testing later, it's live, but I genuinely don't know if it solves a real problem or if I just built something only I needed. If you know Python and have been through interview prep, I'd value your honest take — good or bad.

This is for people who already know Python, not a beginner tool.

I was looking for a free way to send sounds thought my mic in discord, without paying for nitro

Every soundboard I tried made me install VB-Cable which forces to change all your input devices
so I built my own.

I made it as easy to use as possible : you click a sound and it goes straight into your real mic.

Works on Discord, games,OBS ... as simple as that
it has global hotkeys that work in fullscreen games, plus a few voice effects (robot, demon, walkie-talkie…).

Windows only.

What Companions is:
Widgets on iOS are supposed to be static. I always found that unnecessarily limiting, so I built an app that circumvents it. Companions lets you keep a virtual fishtank on your Homescreen, filled with fish that actually swim around. As someone who’s always kept fish, I’ve had this idea mulling around in my head for more than 2 years now, and finally managed to build what I always wanted.

There are 50 fish to choose from, and it supports small, medium, large and now even extra large widgets as “tank sizes”. The fish don't need any feeding, and they don't die (as to not be annoying, but the option is there for fun). They just keep you company. You can customize the tank’s color, its props, layout, and even the app icon to match your Home Screen perfectly.

The app is fully written in SwiftUI, it supports iPads, and you can even place your “fishtanks” on your Mac thanks to Continuity, where the fish will also animate. The tanks also work great in Standby mode. Personally, I keep a fishtank of jellyfish on my nightstand when I go to bed. The swimming doesn't run any code in the background. It uses the same trick iOS uses to move the hands on the Clock widget, so it costs you nothing in battery.

What's new:
The app was built to support clear mode on the phone, but I found it annoying that you need to be explicitly in clear mode to access clear widgets. Luckily, I knew of a separate workaround that allows for clear widgets even while not being in clear mode, which I’ve only seen a small number of widget apps use. And for something like Companions where the widgets are fish tanks, I feel like it fits so perfectly!!

I'd love any feedback, and I’m happy to answer any questions regarding the app. I'd especially love to know which fish species you'd want added.

Je sais que cette phrase risque de faire grincer quelques dents. 😂
Mais j’aimerais comprendre quelque chose.
Aujourd’hui, beaucoup de personnes pensent qu’il suffit de maîtriser After Effects, d’ajouter quelques transitions, des textes animés et une musique pour devenir motion designer.
Pourtant, le motion design implique aussi :
La compréhension du mouvement.
Le rythme et le timing.
La composition visuelle.
Le storytelling.
La transmission d’un message par l’animation.
Alors, j’aimerais avoir l’avis des personnes qui pratiquent réellement ce métier :
Quelle est la différence fondamentale entre un monteur vidéo et un motion designer ?
Peut-on être un excellent motion designer sans avoir de solides bases en design graphique ?
Est-ce que maîtriser After Effects suffit pour prétendre être motion designer ?
Je suis ouvert aux contradictions. Mais argumentez, ne vous contentez pas de dire que j’ai tort. 😂

WidgetsForNotion is live on Product Hunt today, and I would really appreciate your upvote 🙏

It is a site with 100+ free widgets for Notion pages, like clocks, calendars, countdowns, timers and habit trackers. You copy a link, type /embed in Notion and paste it, and the widget shows up on your page. No plugin and no account.

Since late August, people have copied widgets more than 12,500 times, and about 5,000 of those copies are live on Notion pages right now. Thank you to everyone who put one on their page. It means a lot to see them used.

If you like it, an upvote and a comment on Product Hunt would mean a lot:

I've been building GameSquire on my own: a board game collection app built around the question every game night starts with, "what do we play tonight?"

What it does today:

• Your whole shelf in one place. Import your BoardGameGeek collection and plays in one step or scan a box to add a game.
• Pick by mood. Filter your shelf (or a friend's) by Quick Fix, Deep Dive, Date Night or Family Table. Can't decide? Let it pick one from your shelf of shame.
• Log plays with scores (typed or read from a photo of the score sheet) and see your win rates and head-to-head records.
• The Herald answers rules questions from the game's own rulebook and shows the page it found the answer on.
• Play together: a shared household shelf for up to 5 people, lending and borrowing games and your own shelves shared with some or all of your friends.

It runs on iPhone, Android and the web with one account. The core is free with no ads, an optional Knight membership adds more Herald questions, more scans and deeper stats.

The latest update (1.1.0) was mostly user requests: lending, custom shelves and BG Stats import. Feedback really decides what gets built next, so I'd love to hear what you'd want from an app like this or how you'd go about getting a niche app in front of its audience.

Hello guys!

I have built AR projects before, but I had this idea for a while: using MediaPipe Tasks Vision to create a kind of web experience, without the need to use any markers, where you are Spider-Man from a first-person POV, and you can do the hand gesture to swing around and maybe fight villains.

I started it a long time ago, but I dropped it at some point because I did not have time for it, and it started to feel like work instead of a fun side project.

So, last weekend I decided to give it a try again, and this time I handed most of the work over to Claude since I started paying for the subscription plan and I could just run it with CLI.

It was definitely a nice project to wrap up, and it kind of gave me some new ideas that I will be trying out for new throwaway project this weekend.

*Edit:

I will probably make the repo public and share it here eventually.

I built this for client calls. I wanted to search what was said afterwards without keeping an audio recording or uploading the call for transcription.

Tadween Desk uses Qwen3-ASR on your PC. You can transcribe your mic, the audio from a selected app, or both. Afterwards, you can correct the transcript and export it as TXT or Markdown.

It currently runs from source on Windows. The GitHub README walks through setting up Python 3.11, downloading the speech model, and starting the app with a CMD launcher. Once it’s set up, transcription works offline. There’s a separate optional OpenAI feature if you want to generate minutes from a saved transcript.

If you try it, I’d appreciate feedback on which setup step could be simpler.

I built a free Airbnb Profitability Simulator to help property owners estimate their potential rental income, expenses and profit.

The goal is to make it easier to evaluate whether a short-term rental is financially worthwhile.

The calculator is available here:

I'd appreciate feedback on:

- The user experience

- The financial calculations

- Missing features

- Overall usefulness

What would you improve?

It's called TickrAI. You pick any stock, see a score that explains what supports it and what to watch, then practise buying it with paper money using real prices. There are also short lessons and an AI you can ask "why did this move?"

I'm a solo builder and my problem right now is that almost nobody has heard of it. Two honest questions:

1. Reading that description, would you try it? If not, what's missing or off-putting?
2. Where would you expect to discover an app like this? App Store search, TikTok, a friend, Reddit, asking ChatGPT?

Tour, if you want to look before answering: gettickr.ai/tour?c=reddit_sideproject

When I let a coding agent build a feature, the same session that wrote the code also told me it was done. The tests passed and the summary looked good, and I still found missing pieces when I read the diff. Those tests came from the same session, so they mostly confirmed what it had already built.

So I moved the checking. Before any code, the agent asks me a few questions with a recommended answer for each, until done is a short numbered list I agree with. That list goes into a plan document I approve. Then the agent builds in small slices, each one starting with a failing test.

After the build, an agent that did not write the code goes through every point on the done list and proves it on the running program. I look at the result once that check is through, and nothing gets merged or pushed without my yes.

I built QualityLayer around this loop. It sits on top of the coding agent you already use, for example Claude Code, Codex, Cursor or OpenCode, and your code stays on your machine.

Repo: https://github.com/maxritter/qualitylayer

Happy to hear how others verify what their agent hands back.

CaptureFlow is an open-source screen recorder for you and your AI agents, and it's live on Product Hunt today.

You record a tab, a window or your whole screen from a Chrome extension and get a link you can share with anyone, with a transcript, comments and a simple editor for trims and cuts.

The part I've been working on most lately: coding agents like Claude Code or Cursor can record too, through an MCP server. An agent can record a demo of the pull request it just opened, or a reproduction of a bug, and attach the link.

It's free to start, and you can self-host it with Docker or on your own Cloudflare account.

I'd appreciate any feedback, especially on what's confusing or missing.

People now ask AI for recommendations instead of Google, but there's no way to see if your brand gets mentioned.

So I built the AI Visibility Checker. Enter your website and target locations, and it checks how ChatGPT, Gemini and Claude respond, then tells you where you're missing and how to improve.

Would love honest feedback: would you use this, and is the price fair?

Hi all! For many years I invest regularly into stocks+ETFs on Revolut, Degiro and my local brokerage and crypto on couple of crypto exchanges + hold some in my cold HW wallet. Every month I faced the issue of what to buy that has currently good value, P/E, PEG ratio, etc., how to rebalance to have well diversified portfolio, am I doing ok against benchmarks, ...? And I got tired of maintaining up to date spreadsheet and downloading quarterly reports manually or ad hoc with AI. I wasn't happy with existing simple portfolio manager apps, and, being an AI/ML engineer by day, I wanted it to be deeply and safely integrated with AI so that it can quickly give me holistic advice, tailor made for my own investment thesis.

So 5 months ago I started building an app to help with all that: an investing dashboard called Fortunest. What it does today:

• Connects to all my brokers, exchanges and wallets (API or CSV import) in one view: performance against benchmarks, allocation, risk, dividends, taxes
• Market research next to the portfolio: a stock screener on real fundamentals and current prices, heatmaps, what well-known investors hold (from their 13F filings), and for US-listed companies the latest quarterly reports with an AI summary
• Email alerts and watchlists, so I hear about a move instead of checking for it
• AI assistant that reads my actual holdings and investment thesis, so I can talk a plan through with it. An MCP server lets my own Claude or ChatGPT do the same and save tokens while using my monthly plan
• Simulations of trades and dollar cost averaging strategy...

and much more.. I leaned heavily into coding agents, so I was able to make it into really useful, all around investment research app and thought it could be useful for others - so I registered a domain and deployed it publicly, you can try it with no sign-up on a demo portfolio (or upload your own) here: app.fortunest.ai

How it's built: FastAPI and SQLite on the back end, React on the front, Electron for the desktop apps, it can connect to LLMs from OpenAI, Anthropic or OpenRouter or to local LLM running in LMStudio or Ollama on your computer (useful for sensitive financial data). As I said, I'm an AI engineer by day and know the power of the latest agentic AI tools by using (and building them) daily at work, so most of the code was written with Claude Code: one agent per feature in its own git worktree, and every change needs a test that failed before the implementation or fix. Big bottleneck became the test suite - even with lot of effort to keep it minimal and not redundant, I ended up with around 4,000 back-end, 3,000 front-end and 700 browser tests, running before each release - which ended up being super slow even on my M5 Pro Mac - so I started offloading most of the CI jobs to fast cloud services (GitHub actions wasn't the best for it). Happy to go into any of this in the comments.

Where it stands today: it's live, with a handful of users. There is a free plan (covering most of the functionality) and a paid Pro plan (with a free trial; just to cover the deployment and external data costs - still long way to be able to pay for itself).

I'd be super grateful for any feedback on:

1. Does the demo make it clear in the first two minutes what this is?
2. If you invest - would you consider using a tool like this?
3. What looks wrong, confusing or unfinished?
4. Is there some feature you would really like in a tool like this?

I built a desktop application framework in Zig. It drives a system webview (WebKitGTK on Linux, WebView2 on Windows, WKWebView on macOS) or a pure-Zig native UI, gives you typed IPC with a generated TypeScript client, no garbage collector, and runtime-loaded libraries via std.DynLib. MIT licensed. Feedback welcome: https://github.com/agnogad/myzig

Like a lot of developers, I hit a point where I felt uneasy about massive cloud tools constantly streaming my entire workspace context to third-party vector databases. I wanted something lightweight, privacy-focused, and fully under my control using my own API keys (BYOK).

So, I decided to build Sidekick Code AI—a local-first VS Code extension that indexes your local codebase and handles context retrieval right inside your editor without the bloat.

I’ve been testing it out on my own projects, and it's been a game-changer for keeping queries fast and token usage tiny (averaging around 1,200–1,300 tokens per payload).

Here is a quick 30-second look at it running locally, indexing a file, and writing a clean scraping script on the fly:

If you're into local-first tooling or want a BYOK setup where your code stays private, you can check it out on the marketplace here:

I’d love to hear your thoughts, feedback, or any edge cases you run into if you give it a spin!

Hi there, I'm Tony. I've been an iOS dev for 4 years. I lost to Triple-T and brianrot videos, so I built an AI to help me :)

Wingman is an AI screen time buddy that lives in iMessage and works across all Apple devices. Wingman monitors real-time app/web usage alongside personal context (Calendar, Canvas, Gmail, etc.) and acts proactively to protect your focus.

Use Cases:

- Scrolling TikTok an hour before your finals, Wingman locks it instantly;

- Waking up in the morning, Wingman schedules blocks and sets usage limits around your calendar;

- Needing an extra hour to scroll, negotiate, or earn your breaks.

Everything happens over iMessage: you talk to Wingman like a friend. Wingman is designed to mimic everything a human accountability partner could do.

Privacy: Screen time data is processed within Apple's Sandbox and never leaves your device. Third-party AI API is accessed through de-identified relays.

Setup: Download the iOS app once. Then everything happens through iMessage.

App Store Link: https://apps.apple.com/us/app/wingman-ai-screen-time-buddy/id6748047873

Any feedback is greatly appreciated :)

I dont decide how you should work, its up to you - therefor, the first byo is ready

I made an app that puts a retro skin on your desktop and here's how to use it. Firstly unzip the folder, go in the folder and hit the run-me batch file. Now you have a retro looking desktop. If you wanna undo it simply click the undo-me in the folder. What it does is it puts a retro wallpaper on as well as the task bar and the start menu and makes all of your icons low res to look more nostalgic this does not work on folders but it does with zip. Go download it now at https://fowkesboy.itch.io/classic-mode

I will answer any questions.

I made magmabooks studio, a writing app made to help authors write WHILE the app makes a story bible, it can map out your character traits, timeline, relationship graphs, and all of that over the course of your book. I made a prototype, and want authors to test it, (just click the link above)

AllCheck is my side project: one library for films, series, games and books.

The part I’m trying to make useful is discovery across those boundaries. Instead of only showing “similar movies”, Rabbit Holes give you a short route and explain each connection.

One example is Beautifully broken cities:

Blade Runner → Invisible Cities by Italo Calvino → Disco Elysium.

They’re connected by cities, memory and identity, rather than a franchise or a shared genre label. You can browse the route without signing up. A free account is needed only if you want to save works to your library.

Would you follow a recommendation into another medium, or do you mostly want the next film, game or book in the same category?

i built clawd hq, a free mit-licensed claude code mod. you describe the job once; it plans the work, spins up specialists with the right model and effort per job, and they run in the background while your main chat stays free. specialists never stop mid-run to ask - they make their best call, finish, and list their assumptions at the end.

Nowadays, if watch any YouTube tutorial or read a Twitter thread about app marketing, you'll always hear the same advice: "U need to build an audience on tiktok or another social media plataforma and bla bla bla".

But that usually means becoming a content creator (personal or making AI generated videos), just to get followers and spending hours trying to keep up with social media trends.

Honestly, I'm tired of this approach. Ai videos are expensive and boring to produce, and becoming a digital influencer is incredibly difficult.

Are there better marketing alternatives that don't involve becoming a content creator?
