PrismCad

What it does

PrismCAD is a local-first, zero-trust AI assistant designed specifically as a plug-in for AutoCAD 2025 and 2026. Unlike generic cloud-based AI tools that operate as unpredictable black boxes with direct access to production files, PrismCAD bridges natural-language intent with strict deterministic execution. It utilizes a decoupled architecture a planning sidecar communicates via loopback with a high-performance C# AutoCAD kernel, ensuring that proprietary drawing files never leave the local

Use plain English to automate supported AutoCAD tasks. PrismCAD turns requests into reviewable CAD operations and executes them only after approval.

  Simple algorithm and color space to generate diverse skin tones▲627

  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 model to autocomplete piano on-device▲598

  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.
