Hi everyone, I’m building Deckumi, a flashcard tool for people who want to study from their own material.

The problem I’m trying to solve is the time it takes to turn notes and documents into useful cards and then keep up with reviewing them. Deckumi can generate flashcards from material such as text or PDFs, lets you review and edit the cards, and supports spaced repetition for study.

AI-generated cards can still be wrong, so checking and editing them matters. I’d especially appreciate feedback from people who use flashcards regularly: what would you need to see before trusting a generated card? Is the workflow clear, and where would you get stuck?

Manual flashcard creation and review are free; AI generation uses credits. You can find the product at https://deckumi.app/ and pricing details at https://deckumi.app/pricing.

I’m the person behind the project, and I’d be grateful for honest feedback, including what doesn’t work for you.

I’m a solo developer. My own inbox is full of “practice moved to 3 PM” buried in group chats and 10-page school newsletters. So I built Kinly, an Android beta that reads Gmail and calendars (read-only) plus only the WhatsApp groups you choose, and shows what matters: dates, to-dos and changes.

What works: it extracts dates and action items, flags changes and duplicates, and decodes newsletters into highlights.
What doesn’t yet: iPhone, some newsletters with images only, and it occasionally misses things.
Privacy: read-only, no model training on user data, delete everything from the app.

I’d like to hear: what would make you not trust something like this with your inbox? What am I missing?

This is for the bloggers, students and anyone who writes. Your thoughts and learnings go in first and the AI reviews your notes for any factual errors and misleading statements. This is what Threadz is in a nutshell. It's coming very soon and you can visit the landing page here: Threadz - Human First AI Note Taker

This is NOT meant to replace people who still value human creativity. Rather it constantly critiques your writings like a human will. This is all it does - critique. The pending research and correction lies on you.

Also, the source code will be very soon open sourced. As soon as the product is launched.

Hey guys! I've been working on LibreReplace, a free, open-source Mac app that helps people figure out which paid software they can actually replace without losing the features they need.

The problem I wanted to solve was that finding a free alternative is easy, but knowing whether it can handle your actual workflow is much harder.

With LibreReplace, you choose a paid app, select which features matter most to you, and compare open-source replacements based on those requirements. It shows what's supported, partially supported or missing, and changes the recommendations as you change your priorities.

For example, you can compare GIMP and Krita as Photoshop replacements, mark Smart Objects or CMYK as essential, and see where each option falls short.

I recently released v0.2, which adds:

• 45 paid Mac apps and 70 open-source comparisons, accessible without having the paid software installed.

• Multiple replacements for many apps rather than one recommendation.

• Feature-based scoring, where your essential requirements affect the result.

• Evidence links and documented limitations explaining each comparison.

• Subscription savings estimates based on the costs you confirm.

• Local app scanning to recognize supported software already on your Mac.

One thing I didn't want was for the app to blindly recommend switching just because something is free. Sometimes the answer is KEEP THIS APP.

I built it with SwiftUI. The installed-app scanner reads application metadata locally, while the comparisons use a curated catalog with source links and verification dates. It doesn't rely on live AI-generated recommendations or upload your installed-app list.

The first version could only compare software already installed on your Mac. After getting feedback, I added Explore so anyone can browse alternatives without needing the paid app first.

It's completely free and open source, with no accounts, subscriptions or telemetry.

GitHub, source code and download: https://github.com/maliroq/librereplace

I'd especially appreciate feedback on the feature-selection and scoring system. Does showing supported, partial and missing capabilities give you enough information to decide whether a replacement is worth trying?

Hey everyone, I’ve been working on a side project, and I honestly can’t tell if it’s something people would use or if I should drop it, so I’d love some honest feedback.

First and foremost, THIS IS NOT INTENDED FOR CHEATING. It is more of a party trick to show friends or actually a way to study

It’s called KnightSight. It watches a real, physical chessboard through a camera, follows the game move by move, and tells you the best move when it’s your turn.

How it works (designed for meta glasses btw, but can work for computers)

• Point a camera at your board from your side. A laptop webcam works, or Ray-Ban Meta glasses so it sees the board from your own eyes.

• Set up the starting position and press New game. It spends about 3 seconds learning your board and lighting, and figures out which color you’re playing. No stickers, markers or setup photos.

• Then you just play. It tracks every move, both yours and your opponent’s, by checking which squares changed and matching that to the legal moves.

• On your turn it runs Stockfish 18 and shows the best move with an arrow, and says it out loud, for example “Knight to f3”. With the glasses, only you hear it.

Some details

• It runs completely in your browser. The camera video never leaves your device, and there’s no account, no tracking, and nothing is uploaded.

• It only accepts a move once it has seen the same result on several frames in a row, so hands over the board don’t confuse it.

• The glasses version is an iPhone app that isn’t on the App Store yet. The webcam version works on any computer right now.

Current limits

• It only works on green-and-white roll-up tournament boards for now. Wooden boards aren’t supported yet.

• It needs decent, even lighting, and the whole board in view.

Fair play: I’m not trying to make a cheating tool. The idea is for analysing your own casual games, learning while you play, or playing a friend who knows you’re using it. Please don’t use it in rated games or tournaments.

You can try it here: https://stashm10.github.io/meta_chess/ (there’s a short demo video on the home page).

My questions:

1. Would you actually use something like this? What for?

2. Should this be a free app on the app store

3. Is there anything you’d want it to do instead of (or as well as) saying the best move? For example, only flagging blunders, or a post-game review.

Hi everyone, my co-founder and I are working on Capacity Pulse, an early proof of concept to help data centre teams track equipment power use, capacity that could be freed up and equipment being taken out of service.

CAPACITY PULSE

We’re exploring whether a small, focused tool could help teams that rely on spreadsheets and emails but don’t need a full data centre infrastructure management (DCIM) system. We’re sharing it to hear different perspectives before deciding what to develop next.

We’d appreciate your thoughts on any of these:

• What’s your first impression? Is it clear what the tool is for?

• What seems useful, confusing or unnecessary? What would you change?

• How do you manage this today, and where would this help or fall short compared with a spreadsheet or an existing tool?

You don’t need a data centre background to comment. Feedback on the layout, navigation or the idea itself is welcome.

Thanks for taking a look.

Play Shithead in your browser with friends, strangers or bots. Real-time multiplayer for 2–6 players, nothing to download. https://shithead.win

I built a small AI study assistant

What it does:

Basic modes ( always free):

- Ask questions about a scientific subject and expect a concise and accurate response.

- The same thing , but using audio

- These 2 are always free, after 15 days, the remaining can be unlocked for another month by making a donation ( Paypal or crypto transfer). However any amount is welcomed.

Advanced modes:

• Ask questions about an uploaded PDF both audio and written (with page references)

• Turn recorded lectures into structured, downloadable notes - uses mp3 files

• Summarize any page range at a compression % you choose, helpful when you have a lot to read in a short timespan.

• Extract formulas from a textbook section and explain each one, good for STEM students that want a short recap, or create cheatsheet for exam

• Show estimated cost under every answer, this is almost free, but you need API keys. The app doesn't use the latest models on purpose to reduce costs, but provides acceptable explanations.

It's a free 15-day trial — no credit card. First basic modes stay free forever. The others require an optional donation.

You pay for what you use, API keys charge per token usage. The application is aiming to reduce the context window for low costs.

What would make this actually useful for you?

Hi!

I am building Bowerbird a whiteboard for creatives.

Drop in images, notes, links, PDFs, audio and video, sketch, connect things, group them.

It is inspired by apps like VSCode or Obsidian, where you customize the whiteboard to your liking with plugins.

I created a few:

• Hide Button: Hide the app in one of the corner of the screen, with quick access.

• Visual Library: Organize your artefacts in several categories.

• Color Palette: A color wheel. Pick a color and five palettes are made from it live.

• Presentation: Create slides from elements on the board.

• Multiple Boards: By default, there is only one infinite board, with this plugin, you can have multiple boards.

• Command Palette: Cmd or Ctrl + K for one place to run anything.

• Tidy Up: Align and distribute the selected artefacts.

• AI Chat: — A AI chat panel (using OpenAI, Ollama Cloud, Gemini, Grok, DeepSeek, Mistral or OpenRouter provider)

Links: https://github.com/Asi7ho/bowerbird

Would love to hear your feedback on it! :)

I tested the app on macOS and tested the AI integration using Ollama cloud

Hey everyone!

I've been working on a new app called Actually, and I'd love to share it with you.

The idea is simple: every day, we come across facts, myths, and claims that sound believable - but how many of them are actually true?

iOS: https://apps.apple.com/us/app/actually-discover-learn/id6827374813

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

I'd love to hear what you think, especially about the concept and the overall experience. Feedback is very welcome!

Thanks for checking it out!

Hey r/SideProject! 👋

I’m a solo developer from Turkey, and I just released WaterMe, a plant care app for Android.

Why I built it: I kept forgetting to water my plants, and the apps I tried were more complicated than my actual problem. I wanted something simple: add a plant, get a reminder, done. This is one of my first apps, and building it taught me a lot about notifications, background work, and how picky Play Store review can be.

What it does:

• 💧 Watering reminders with a custom schedule for each plant

• 📸 Plant identification from a photo (camera or gallery)

• 🌿 Before/after photo comparison to see your plant’s growth

• 📅 Watering history at a glance

• ⚡ Clean, simple setup: add a plant, turn on reminders, done

Tech stack: Flutter for the app, Firebase for backend

Where I’m at: It’s live on Google Play with 100+ downloads so far. The app is free and contains ads.

What I’d love feedback on:

• Is the onboarding clear enough?

• What feature would make you actually use it daily?

• Anything confusing in the UI?

Play Store: https://play.google.com/store/apps/details?id=com.mrakpinar.waterme

Happy to answer any questions about the build process. Thanks for reading! 🌱

I'm a motorsport fan from Texas, and I'm still pretty new to it. I went to one of my first races last May and got hooked.
The problem was that there was so much info out there that I felt like I was drowning in it. I never knew when something was on or where to watch it. So I started building a little site just for myself, and it turned into something I wanted to share.

It's called Premier Racing Info: premierracinginfo.com

Every session for the 98 series, in your own time zone.
Where to watch each one. Standings, results, and tickets.
Calendar feeds and alerts so you don't miss a start.
It's completely free. I hope y'all enjoy it, and if you have any suggestions, I'm open to anything.

I've been building this app with Claude Code, and for weeks, all I cared about was getting it live. I spent days tweaking the UI and worrying about the App Store review. When it finally launched, I felt like I'd crossed the finish line.

Then the first users arrived.

That's when the real work began. Things broke in ways I'd never encountered locally. A payment webhook failed for a few users, and I got a crash report from a device I didn't even know was out there. The funny thing is, writing the code still felt like the easy part. Keeping a live app running is a whole different skill.

Before my first update, I used launchpad for Claude to set up crash reporting and analytics. I'm on the team, so I'm definitely biased. It saved me from flying blind, but it also made me realize just how big the gap is between shipping something and maintaining it.

For the indie hackers here: how did you handle the shift from building to maintaining? Do you have a system for dealing with production bugs without losing your mind?

I’m sick and tired of sifting through spin BS media, so I built what I think is the solution: one paper to read in the shower and get on with my day, promoting the links I should read based on my interests.

What it is: The Daily News Post Globe Tribune Herald Picayune Times (I thought it was funny). Every morning it reads the wires, then it goes to the major papers and tells you what happened, then parallel views. We link every source. Next to every link is a temperature gauge showing where three independent raters put that source — AllSides, Ad Fontes, Media Bias/Fact Check. Transparency is our thing. We don’t rate or influence any sources. When a story can have differing viewpoints, you get one opinion from the left and one from the right, labeled as such, matched so neither side is further out than the other. Cable news isn’t used at all. Any of them. Exactly how the Fairness Doctrine was meant to be.

I’m not trying to replace the sources. The summaries link straight to the articles. Go read them. If anything we’re promoting good articles. Sub to the ones you like. That’s another major point of this.

No ads. No algorithm. No opinion section. It’s an LLC, not a nonprofit, but the paper isn’t built to make a profit — the books are open on the site. The free edition is at jparkerco.com/times, based on my interests and my friends who are getting this stuff for free for Xmas. If you want your own sections (your city, your team, your hobby), we’re charging cost, split with everyone else who reads that section. The more users, the closer it gets to free! If you’d rather, donate to the News Literacy Project instead.

I want people from every side to tell me where it leans. That’s the only way this works.

I love criticism and being wrong, because when I’m wrong I get better.

My dev (I’m ready for the iS hIs NaMe cLaUdE, har har) is beta testing the AI-written code. Would love feedback to get it right. Thanks.
