Stay in flow. Talk, don't break stride.
On-device, no cloud round-trip.
Knock out commit messages, PR descriptions, docs, and Slack replies by voice without losing focus. Private mode runs on your Mac, so there's no server in the loop, and it works on a plane.

Built for how you actually work
It's not the code that slows you down, it's the PR description, the Slack reply, the doc, all the writing around it.
No round-trip latency
Private mode transcribes on your Mac, so words appear about as fast as you stop talking, no server hop, and it works fully offline.
Knows your stack
Add library names, acronyms, and jargon to your Dictionary so 'PostgREST' and 'kubectl' come out right, not phonetic.
Commit vs. PR Styles
A terse imperative style for commits, a thorough style for PRs and docs, applied automatically by app.
Nothing leaves your machine
In Private mode, no audio or text is uploaded, your work and your words stay local.
Say 'there's a bug', get the report
Intent mode turns a rough thought into the finished artifact, a bug report, an AI prompt, a Slack update, or a task list, ready to paste.

Your voice never leaves your Mac.
Private mode transcribes on your Mac and uploads nothing, your code context and dictation stay on your device, even offline. And every word is written to a searchable history the moment you finish, before it even pastes, so you never lose a thought.
Questions developers ask
Does it work in VS Code, the terminal, and the browser?
Yes. Mutter types wherever your cursor is, so it works across your editor, terminal apps, and the browser.
Will it spell library and tool names correctly?
Add them to your Dictionary once and Mutter renders them exactly, no more phonetic 'cube cuddle' for kubectl.
Does it work offline?
Private mode runs entirely on your Mac, so it works with Wi-Fi off, on a plane, in a SCIF, anywhere.
Is my audio or text sent anywhere?
Not in Private mode, nothing is uploaded. Cloud mode is optional and clearly separate.
