    Composer – AI architect / MCP for software architecture diagrams▲8

    Hi everyone! I built Composer, which is a tool turns your ideas into architecture diagrams. You can also use MCP to turn your EXISTING codebase into a visual diagram! It connects to all possible tools using MCP (Claude Code, Codex, OpenCode, etc.) The goal was to make system design easier and to be able to draw out what I wanted to make before I started / to explain to others. Its currently live at usecomposer.com and free! I’d love feedback on whether it feels useful for real projects and where it breaks down. :) Thank you

    Voice Composer – Browser-based pitch detection to MIDI/strudel/tidal▲32

    Built this over the weekend to bridge the gap between "can hum a melody" and "can code algorithmic music patterns" (Strudel/TidalCycles) for live coding and live dj'ing. What it does: Real-time pitch detection in browser using multiple algorithms: CREPE (deep learning model via TensorFlow.js) YIN (autocorrelation-based fundamental frequency estimation) FFT with harmonic product spectrum AMDF (average magnitude difference function) Outputs: visual piano roll, MIDI files, Strudel/TidalCycles code All client-side, nothing leaves your machine Why multiple algorithms: Different pitch…
