Sumi – Open-source voice-to-text with local AI polishing

I'm based in Taiwan and run 3-4 Claude Code agents in parallel most of the day. Typing instructions to all of them was the actual bottleneck, so I built a voice-to-text tool that runs both STT and LLM polish locally. Architecture: two-stage pipeline. - Meeting mode: background transcription to SQLite. Start before a call, stop when done.
