Where your words go.In plain language.
The short version
- In Local mode, speech recognition and cleanup run on your Mac and it works offline.
- In Cloud mode, audio goes to a cloud speech provider, and text goes to a cloud writing model when it needs cleanup.
- In Both mode, audio stays on your Mac; easy text stays local and harder text can get cloud help.
- Your history is encrypted on your Mac.
- Analytics are off unless you opt in, and never include what you say.
- Your early access email is used only to contact you about Presto.
What stays on your Mac, by mode
| Topic | Local | Cloud | Both |
|---|---|---|---|
| Your audio | Stays on your Mac | Sent to a cloud speech provider | Stays on your Mac |
| Speech recognition | On your Mac | Cloud speech provider | On your Mac |
| Text cleanup | On your Mac | Cloud writing model, when text needs cleanup | Easy text on your Mac; harder text can get cloud help |
| Download | 1.37 GB model, once | None | 1.37 GB model, once |
| Internet | Not needed, works offline | Required | Only when text gets cloud help |
Exact edits to highlighted text, like saying “make that four” to change 5:00 to 4:00, run on your Mac with no model involved, whichever mode you use.
In Cloud mode, what goes where
- Your audio is sent to a cloud speech provider, which turns it into text.
- If that text needs cleanup, such as resolving a correction or formatting an email, it’s sent to a cloud writing model.
- The finished text is inserted into the app you’re using. Presto never presses Send or Return.
Cloud mode needs an internet connection. If you’d rather keep audio on your Mac, use Local or Both.
History
Your dictation history is stored encrypted on your Mac.
Analytics are opt-in
Analytics are off unless you turn them on. If you do, Presto only sends events from a fixed allowlist. That allowlist never includes:
- Transcripts or anything you say
- Audio
- Your email address
- File names
