Open-source voice dictation
Speak — and it's typed into any app.
OpenBroca is free, open-source voice dictation. Your speech turns into text in whatever app is focused — powered by the cloud or fully local AI models you choose, with no vendor lock-in.
Free & open source · macOS, Windows & Linux · v0.2.2
Features
Your voice, as a first-class input.
Everything you need to talk to your computer the way you think — open, extensible, and built for daily use.
Dictate into any app
Speak and your words land in whatever window is focused — editors, browsers, chat, the terminal. Voice as a real, system-wide input layer.
Cloud or local ASR
Run Deepgram in the cloud for speed, or Sherpa-ONNX entirely on-device for privacy. You decide where your audio goes.
Rewrite with LLMs
Polish, translate, summarize, and transform what you said on the fly with your choice of 16+ language-model providers.
No vendor lock-in
Swap providers and models freely through open interfaces. Never locked to one vendor, one model, or one workflow.
Custom voice workflows
Compose recognition and language steps into flows that match how you actually work, then trigger them anywhere.
Private by design
Credentials live in OS-backed secure storage, and local models keep your audio on your machine. Your keys, your data.
Bring your own models
Plug in any provider you trust.
OpenBroca speaks to speech and language providers through open interfaces. Mix cloud and local, swap models per task, and add your own — nothing is hard-wired.

After keyboards. 
Before brain interfaces.
“Computers should hear you before they read your mind. Voice should be a first-class input layer — not a narrow dictation box locked to one vendor, one model, or one workflow.”
