Gramit

Diagrams that nest, so complexity stays readable

What it does

Every diagram breaks as the system grows. You get one unreadable canvas or ten disconnected files. In Gramit, any node can contain its own diagram, so you zoom from context to detail without losing the thread. Built for engineers documenting real architectures.

A free whiteboard where every node opens into its own diagram. Flowcharts, system architecture, YAML in and out, AI-friendly — no sign-up, boards stay in your browser.

Gramit is a free whiteboard where any node can open into its own board. Sketch the big picture, then step inside it and keep drawing — one level down, as deep as the system goes. A service is a box — until you need what’s inside it. In Gramit, any node can hold a whole board of its own: step in for the detail, climb back out for the big picture. One document, every altitude. Try the miniature below. Every board speaks YAML. Describe nodes, edges and subflows in the side panel and the canvas draws itself — or sketch by hand and read it back as tidy YAML. Diff it, review it, generate it. There’s a spec written for machines. Paste it into ChatGPT, Claude, Copilot — whichever assistant is…from gramit.io

    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.
