TubeLearn

What it does

Paste a YouTube link. TubeLearn turns available captions into a readable article and quiz so you can test whether you actually learned the material.

Paste a YouTube link. TubeLearn turns available captions into a Lesson — a readable article and quiz you can use to test whether the material actually stuck. You already use YouTube to study, practice, and prepare. TubeLearn just makes sure something actually sticks when you're done watching. Quiz yourself on lecture videos before the exam instead of rewatching them. Test vocabulary and comprehension from real lesson videos, not textbook exercises. Test what actually stuck from a coding tutorial before you close the tab. Turn review videos into a focused Lesson and quiz in one step. Not placeholder copy — actual article and quiz content generated from public YouTube videos. The video frames…from tubelearn.app

  Anki/Duolingo-like app using educational YouTube videos2024 · platoedu.org · ▲289

  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!

  TubePen – My attempt to get more out of YouTube learning2025 · tubepen.com · ▲74

  Hi HN! I made this because I always forget what I'm trying to learn from YouTube. Test yourself: Can you remember the main concepts from the last (educational) video you watched? So, why not highlight and take notes on YouTube videos, just like in books? That's TubePen. Sign in, replace "youtube" with "tubepen" in your YouTube URL, and you're ready to retain more from your videos. I’d love your feedback! What do you think of my landing page? Use the 10-day free trial and see if it’s useful for you. Thanks!

  Turn any YouTube video into a summary, quiz, & flashcards2024 · asterlab.io · ▲5

  YouTube is the greatest learning resource in the world. Yet it doesn't provide any tools to help you learn from videos. I built a simple app that turns YouTube videos into structured learning material using AI. It generates a summary, quiz and flashcards from video content, meaning you can learn from anything (well, at least any YouTube video). Try it out. Would be happy to keep building features based on feedback!

  Platform to discover educational YouTube videos2023 · edutube.app · ▲16

  Hey HN community, excited to share a project that I've worked on. On EduTube you can discover 1000+ hand-selected educational YouTube videos. YouTube has a lot of really great educational content but it's hard to find the really good ones. Personally, I find that the recommendations page often falls short, and I've lost count of how many times I've struggled to select a video to watch while eating, only to end up with cold food. There are a couple of categories that are free and if someone wants to have access to everything there is a 20$ one time payment. I always appreciate feedback if…

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  OpenSEO▲928

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
