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!

I built a tiny LLM to demystify how language models work▲915
Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

I built a frontpage for personal blogs▲783
With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
