Talk to your coding agents.
On-device voice-to-text for macOS. Press right ⌘, speak, then press it again - your words go straight into Claude Code, Codex, Cursor, OpenCode or any other agent, wherever your cursor is.
Install
brew tap satyaborg/blurt
brew install blurt
Or via pipx:
pipx install blurt
Requires macOS with Apple Silicon.
First run downloads the selected transcription model once. macOS will prompt for Microphone and Accessibility access (System Settings → Privacy & Security).
Usage
| Action | Description |
|---|---|
| Press right ⌘ | Start recording |
| Press right ⌘ again | Stop, transcribe, paste at cursor |
| Ctrl + C | Quit |
Models
| Mode | Model | Use case |
|---|---|---|
fast |
Whisper Base | Default, lowest latency |
accurate |
Whisper Large v3 Turbo | Higher Whisper accuracy |
qwen |
Qwen3-ASR 1.7B 8-bit | Experimental accuracy mode |
blurt mode qwen # use experimental Qwen3-ASR
blurt mode accurate # return to Whisper Large v3 Turbo
blurt mode fast # return to the default
Qwen mode downloads an approximately 2.5 GB MLX checkpoint. Custom words and repository file names are passed to Qwen as transcription context. Existing Whisper models remain available when you switch modes.
Custom Words
Teach Blurt words it gets wrong (names, jargon, acronyms):
blurt add "Claude Code" # add a word
blurt vocab # list all
blurt rm "Claude Code" # remove
Words are stored in ~/.blurt/vocab.txt (one per line).
@-mentions
Run Blurt from a git repo and spoken filenames automatically resolve to @path/to/file references that coding agents understand. For example, saying "check init.py for the bug" becomes check @blurt/__init__.py for the bug.
Transcript History
blurt log # view recent transcripts
Logs are stored in ~/.blurt/log.txt.
Update
blurt upgrade
