The short version: it types what you say, and your voice is nobody's business.
No. Recording, transcription, and formatting all happen on-device, and the audio buffer is discarded the moment it becomes text. Flip on Airplane Mode and keep dictating — Voz can't tell the difference.
There isn't much of one anymore. On-device Whisper-class models sit within a hair of cloud accuracy, and with no round trip, Voz is usually faster. The trade: the model lives on your disk — about 141 MB, inside a 149 MB download.
No — and you can check. It uses Web Audio to read the microphone's level for the waveform and nothing else: no recording, no transcription, no upload. It deliberately avoids the browser's speech-recognition API, because in most browsers that does ship your audio to a server. Open the network tab and watch nothing happen.
Any Apple Silicon Mac on macOS 13 Ventura or later is the sweet spot. The same universal build runs on Intel and works fine — transcription just takes a beat longer.
Sixteen languages, with automatic detection. Auto-detect listens to the opening audio, so on a noisy room or a very short clip it helps to set the language explicitly. Custom vocabulary works in every one of them.
