Decisi Tree
The decision tool that argues with itself first
What it does
Decisi Tree breaks a problem into sub-problems, risks, and requirements — then flags what's missing before you decide. It compares solution paths with no fabricated scores, only real tradeoffs. For your top option, it runs a business feasibility check, a cognitive bias check, and a stakeholder map. Then it stress-tests the decision: pre-mortem, failure modes, mitigations, and an independent red-team review. A decision log tracks outcomes, so your next call learns from this one.
DecisiTree turns messy strategic decisions into structured, auditable, AI-augmented decision trees. Evaluate, de-risk, commit, and learn from every decision.

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. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

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.
