Hi HN, I built https://rebrain.gg. It's a website which is intended to help you learn new things. I built it for two reasons: 1. To play around with different ways of interacting with a LLM. Instead of a standard chat conversation, the LLM returns question forms the user can directly interact with (and use to continue the conversation with the LLM). 2. Because I thought it would be cool to have a site dedicated to interactive educational content instead of purely consuming content (which I do too much). An example of a (useful-for-me) interactive conversation is:…

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!

I've been working on this tool that lets you build a personal knowledge graph from articles, blog posts, podcasts, YouTube videos, and other content you find interesting online. You can safely forget everything and trust that Recall will resurface it when something new that is related comes up. Looking forward to your thoughts and feedback on how it could be improved! The original version of Recall was posted last year nov on HN: https://news.ycombinator.com/item?id=33425947 Since then I have pivoted to a browser extension.

I wanted to kick my doomscrolling habit, so I built a microlearning app that uses a TikTok-style algorithm, same addictive feed mechanics, but you actually learn something. I started with a general version, Scroll: Daily Microlearning (microlearning.usescroll.app), but quickly realised it works better when focused on a single topic. So I split it into: Scroll: Personal Finance (https://finance.usescroll.app) Scroll: Learn AI (https://ai.usescroll.app) Scroll: Daily Microlearning (https://microlearning.usescroll.app)

Hi HN, For 4 years I've worked on the psychology of learning following a CompSci degree with an AI minor from back in 2019. I love the future of effective learning that is coming. This is a way for you to study for specific exams, lectures and videos. You upload your content, and get specific, citing flashcard exercises delivered in a fun way. Not only can you view the timestamp in the video that a question was generated from, for example, but your answers are used to inform a "Compilation stage". The Compilation stage uses your choices of answers (and wrong answers), as well as data on when…

Right now it's a Nicotine patch for brain rot/doom scrolling. You still get the scroll, but with more meaningful content. WHERE I WANT IT TO GO: Users mark what they are interested in (e.g. AI, or Space or Whatever), and it should crawl the latest scientific articles, high quality YouTube videos, pods, present it in a format that fits you, in a nice feed. NOW: You can search for anything (e.g. "Sea Explorers" --> The app crawls Wikipedia or YouTube and pulls together a short feed (e.g. Columbus, Vasco da Gama etc.,). I'm using RAG so that I always can reference the original data source…

Hi HN, Would love your thoughts on Open Paper Digest. It’s a mobile feed that let’s you “doomscroll” through summaries of popular papers that were published recently. Backstory There’s a combination of factors lead me to build this: 1. Quality of content social media apps has decreased, but I still notice that it is harder than ever for me to stay away from these apps. 2. I’ve been saying for a while now that I should start reading papers to keep up with what’s going on in AI-world. Initially, I set out to build something solely for point 2. This version was more search-focussed, and…

Hi everyone! First time posting. I built this mini memory game in an attempt to beat lazy memory syndrome. because when was the last time you remembered what you did the day before purely based on memory (or without being prompted) ? Super simple fun game for giving our brains a quick workout and actually reminding it on how to remember. If you had those old Nokia phones from the early 90s, the game will seem insanely familiar to you
