Show HN: Humm – free, private realtime speech-to-text

I found the UX of most speech-to-text apps unnecessarily complicated, so I built Humm as a simple, privacy-first alternative.

Press a custom hotkey, talk, and the text lands in whatever app you're in.

- It runs locally on NVIDIA's Parakeet models - no account and no telemetry

- Works on Windows and Mac

- You can bring your own key if you'd prefer to use cloud models

- Includes a stats page so you can measure timed saved vs typing

- Options to set zero local txt or audio retention

Under the hood:

- Tauri 2

- A modified parakeet.cpp doing realtime transcription, so you see your words as you speak (this feature is windows only for now)

- Qwen3 4B for optional on-device cleanup (rather slow but working on making this better)
