Add "gist" to any YouTube URL to get instant video summaries
Hello HN! Between academics and everything else on my plate, I still find myself watching way too many YouTube videos. So I built `youtubegist` - just add `gist` after `youtube` in any video URL to get an instant summary. Before: https://youtube.com/watch?v= After: https://youtubegist.com/watch?v= I know there are other YouTube summarization tools, but they're either cluttered, paywalled, or don't format summaries the way I need them. So I made my own that's free, open source, and dead simple. One cool thing, if you install it as a PWA (on Android using Google…
What it does
In the maker’s words, at launch
Hello HN! Between academics and everything else on my plate, I still find myself watching way too many YouTube videos. So I built `youtubegist` - just add `gist` after `youtube` in any video URL to get an instant summary. Before: https://youtube.com/watch?v=<...> After: https://youtubegist.com/watch?v=<...> I know there are other YouTube summarization tools, but they're either cluttered, paywalled, or don't format summaries the way I need them. So I made my own that's free, open source, and dead simple. One cool thing, if you install it as a PWA (on Android using Google Chrome), you can share YouTube URLs into it from the YouTube app, and it should summarize the video for you! Please leave your feedback if you tried it out! Thank you!

Hi, I'm Alex. I created Eightify to take my mind off things during a weekend, but I was surprised that my friends were genuinely interested in it. I kept going, and now it's been nine weeks since I started. I got the idea to summarize videos when my friend sent me a lengthy video again. This happens to me often; the video title is so enticing, and then it turns out to be nothing. I had been working with GPT for 6 months by the time, so everything looked like a nail to me. It's a Chrome extension, and I'm offering 5 free tries for videos under an hour. After that, you have to buy a package.…

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
