Common questions
Does my voice ever leave my Mac?
No. Transcription runs on your Mac using Apple’s on-device speech engine. No server, no account, nothing sent out. Post-processing, if you turn it on, runs locally too through Apple’s model.
What happens to my voice recordings?
Deleted as soon as they’re turned into text. The audio doesn’t get saved to disk. Only the transcript sticks around, and it lives on your Mac.
Do the Mac and iOS apps sync?
No. Each app keeps its own history on whatever device it’s installed on. Something you dictated on iOS won’t show up on your Mac. If iCloud Drive is on, the history file gets backed up the same way any Mac app’s data does. That path goes through Apple, never through us. There’s no Dictum database anywhere.
Does it work offline?
Yes. Transcription runs on your Mac’s Neural Engine. Post-processing uses Apple’s on-device model. No internet needed for any of it.
Can I customize the post-processing?
Yes. In Settings, switch post-processing to AI mode and write your own prompt. Tell it to drop filler, fix tone, turn things into bullets, translate, whatever. Apple’s on-device model runs it, so nothing goes to a cloud.
