Chart at the speed you think.
Patient data never leaves your Mac.
Dictate notes, charts, and referrals by voice, transcribed entirely on your device. Nothing is uploaded, so protected information stays where it belongs, and every note is saved the moment you finish, before it even pastes.
macOS 14+ · Any Mac (Cloud) or Apple Silicon (Private) · system requirements
Built for how you actually work
Charting after hours steals your evenings, and cloud dictation tools send protected health information to someone else's servers.
On-device by default
In Private mode, transcription runs entirely on your Mac. No audio and no note ever touches a server, confidentiality by architecture, not a checkbox.
Never lose a note
Every dictation is written to a local, searchable history the instant you finish, before it pastes. A glitchy EHR field never erases your words.
Your terminology, spelled right
Add drug names, procedures, and abbreviations to your Dictionary once, and Mutter gets them right every time.
Works wherever you chart
Your EHR, a referral letter, a quick message, press the hotkey and dictate wherever your cursor already is.
Say it, get the letter
Intent mode turns a spoken thought into the finished referral letter, patient message, or visit recap, ready to review and send, not just a transcript.

Your voice never leaves your Mac.
In Private mode, your dictation is transcribed on your Mac and never uploaded, so protected health information stays on your device. And every word is written to a searchable history the moment you finish, before it even pastes, so you never lose a thought.
Questions doctors ask
Does patient data leave my computer?
In Private mode, no. Transcription runs on-device with a local model; no audio or text is uploaded. Cloud mode is optional and clearly separate.
Is Mutter HIPAA compliant?
Mutter's Private mode is built to keep data on your device, nothing is uploaded, which supports your own compliance posture rather than adding a cloud processor. Always confirm specific requirements with your compliance team.
Can it handle medical terminology?
Yes. Add drug names, procedures, and abbreviations to your Dictionary and Mutter spells them correctly every time.
Does it work inside my EHR?
Mutter types wherever your cursor is, so it works in any desktop or web-based EHR that accepts keyboard input.
