Hold your keyboard's Fn key — Murmur activates instantly, wherever you are.
Talk at your normal pace. Murmur listens using Whisper running locally on your Mac.
Clean, polished text is typed into the active field. Any app, any text field.
Whisper for transcription, Ollama for cleanup. Your audio and text never leave your machine — ever.
Dictate into any text field in any application — Slack, Notes, your browser, your IDE. If you can type there, Murmur works.
Your LLM polishes raw speech — removes filler words, fixes grammar, and formats neatly. What you meant, not what you mumbled.
Hold Fn and talk. Release to finish. No menu bar clicking, no app switching — stays out of your way until you need it.
Choose how your text comes out — polished prose, formal tone, short and punchy, or distilled key points.
The flow bar floats quietly on your desktop. Sub-second launch, minimal memory usage, zero background noise.
Murmur processes everything locally using open-source models. No audio is recorded. No text is uploaded. No account is needed. We can't see your data because it never reaches us.
Download Murmur and start talking to your Mac — privately.
