Turn any topic into a 3Blue1Brown-style video
Hey HN! I built Topic2Manim to automate the creation of educational videos like those from 3Blue1Brown. The workflow is simple: 1. Give it any topic (e.g., "how ChatGPT works") 2. An LLM generates an educational script divided into scenes 3. LLM generates Manim code for each scene 4. FFmpeg concatenates everything into a final video Currently working on TTS integration for narration! Would love feedback on the approach and ideas for the TTS integration

Hello HN! I’m a bachelors student pursuing Artificial Intelligence, Robotics and Signal processing and during the year I had the goal to build my first AI Tool and launch it. I got inspired by how capable Whisper is, and combined the Whisper CPP Bindings along with FFMPEG.Wasm to create a tool that is capable of transcribing and captioning video files that contain one or more video tracks. Along with that, I’ve also added the support for transcribing audio files with the option to export those outputs as .SRT, .WebVTT or simply a text file. All done privately on a user’s web browser with…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
