Hi HN, I watch A LOT of educational YouTube videos but wasn't forgetting a good chunk of the details because I was only really passively watching. So I made a tool that generates quiz questions/flashcards from YouTube videos, and uses spaced repetition like Anki or Duolingo to keep it in memory. Let me know if you find it cool/useful (or terrible ) or if you want to know a bit about the details!

As a student with a lot of notes I had a problem with studying fast for tests. So I created Notiv an AI study app that analyzes your notes and prepares you for test.

Hi HN, I’m Felipe, a 9-5 developer aiming to become a full-time indie hacker. I struggled with flashcard apps that focus on decorating cards instead of learning concepts, so I built FlipCards to solve that problem. What it does: FlipCards lets you: - Create cards for any concept (math, language, coding, etc.) - Add multiple variations per card – the more variations, the better your understanding - Study smarter – the algorithm randomly selects variations so you can’t just memorize Q→A patterns Why it’s different: - Most apps use reverse cards (Q→A, A→Q). FlipCards uses variations to…

Hi HN, University lectures are long, dense, and fast-paced. Like many students, I used to record them thinking I’d revisit them later — but that never really worked. Even transcripts felt like raw logs. So I built [Notorium](https://www.notorium.app) — an AI assistant that records live lectures and automatically turns them into structured notes, flowcharts, and mind maps— within minutes after class. What it does: - Record lectures inside the app (in-person, live) - Transcribe using Whisper - Send the full transcript to LLM - Use a custom system prompt to: - Summarize the lecture -…

The app started as my wishful thinking that flashcards should really be derived from notes. I've been constantly writing things down and wishing to remember them. However, I never could convince myself to populate a flashcard app with them. I really tried (Anki, Supermemo), but I guess regular form filling is not for me. So I've started experimenting with flashcards derived from structured notes. Writing the 1st MVP was fast, but productionising it was way harder. Content synchronisation when the user can work from tube/plane and use multiple devices and content is text is… not trivial.…

Quizlet, a popular tool among high schoolers and college students used to study for tests recently made it's core functionality paid. In an era where Autodesk, Adobe, and Microsoft hold their proprietary software to their chests, it's exciting to see opensource alternatives come to compete with them. I'm 15, and I'm excited to do my part to keep education free for everyone. https://openlearn.vercel.app
