Offline dictation

Dictation that works offline on your Mac

Purr is a free Mac app that turns your speech into text with no internet connection. After its speech model downloads once, during setup, everything happens on your Mac: dictation, meeting notes, summaries and Voice Edit. Nothing you say is uploaded.

Does the Mac’s built-in dictation work offline?

Sometimes. Apple says dictation of general text can be processed on your Mac instead of on its servers, and that Keyboard settings shows whether it is on yours. Dictating into a search box isn’t covered [1]. Purr always runs on your Mac, in any text field, and adds meeting notes and Voice Edit.

What works offline in Purr?

All of it, once the models it uses are on your Mac:

Each one downloads only when you turn on what needs it. Settings › Models lists them all and can delete any of them.

When does Purr go online?

Only to download models and, if you allow it, to check GitHub for updates once a day. There’s no account and no telemetry. Each update shows its release notes first, and Purr checks its signature before replacing the app.

Is offline dictation accurate?

In my tests, Parakeet, Purr’s default engine, got 3.8% of words wrong in everyday speech and 4.0% in hard audio with noise, accents and quiet speech. Wispr Flow, which runs in the cloud, scored 3.4% and 4.0% on the same recordings. Purr put the text on screen 0.22 seconds after I let go of the key. The comparison has the full results.

Which Macs does it run on?

macOS 14 (Sonoma) or later on Apple silicon, so any Mac with an M1 chip or newer. Intel Macs aren’t supported.
