- TMTubePen – 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!


- ISI solved the biggest problem with YouTube learning2025 · notetubeai.com · ▲7
YouTube learning has no structure—your learnings are scattered across random playlists, you're just passively watching without retention, and there's no one to ask when you don't understand something. I built Notetube to solves this by combining organizational tools with AI to create an actual learning system: Organizational layer: Create structured collections by topic/course/skill, track your learning progress with visual dashboards, and set achievable learning goals AI layer: Auto-generated comprehensive notes (3000+ words for 1 hours video) and summaries from any video, key…
- TATurn 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!

Hey we are Computable. We spent years building trading infrastructure at Jump Trading and Coinbase. From that point of view, compute looks like energy markets before 2000: everything trades through private bilateral leases, there’s no visible price, and nothing can be resold. The same H100 rents at a 2x spread depending on who’s asking, and once you sign a 24-month lease, it can never change hands. So we built a market for GPU nodes, sold by the calendar week. Here are three things you can do on it that you can’t do anywhere else: - Buy exactly the weeks you need. Three nodes for the last…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…
