Most AI hands dev-tool founders the same generic sales and marketing advice. The GTM Co-Founder doesn't. It's a set of open-source skills that interview you once, learn your real product and market, then walk you move by move through a prioritised GTM roadmap: who it's for, positioning, your first 50 users, launch, pricing, etc. Grounded in the playbooks of Adam Frankl and Jakub Czakon, plus my own time as a Founding AE and GTM advisor. Free and open source.

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations.

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.
