How to dictate on a Mac completely offline
To dictate on a Mac completely offline, use an app that transcribes on-device instead of in the cloud. Install OpenWhisp, let it download a Whisper model once, and after that you can hold-to-talk and have your speech typed into any app with no internet connection — your audio never leaves the Mac.
Most dictation apps need a connection because they send your audio to a server to transcribe it. That means no signal, no dictation — and your voice leaving your machine. On-device apps flip that: the speech model runs locally, so dictation works on a plane, in a basement, or with Wi-Fi off entirely.
How offline dictation works
Apps like OpenWhisp run WhisperKit (Whisper on Apple’s Neural Engine) directly on your Mac. The model file lives on your disk. Once it’s downloaded, transcription happens entirely on the device — no round trip to a server, and nothing to upload.
Set it up in three steps
- Download and open OpenWhisp (Apple Silicon Mac, macOS 14+).
- Let it download a speech model on first use — this one step needs the internet, like installing any app.
- After that, turn Wi-Fi off if you like. Hold your push-to-talk key, speak, release, and the text lands in the focused app.
Why bother going offline
- Privacy: your audio never leaves the Mac, so there’s nothing to intercept or store.
- Reliability: it works anywhere, with no dependency on a service being up.
- No subscription: local compute is yours, so tools like OpenWhisp can be free.

Frequently asked questions
- Can you dictate on a Mac without internet?
- Yes. With an on-device app like OpenWhisp, the speech model runs locally, so after a one-time model download you can dictate with no internet connection at all.
- Does offline dictation send my voice anywhere?
- No. On-device transcription processes your audio locally on the Mac; nothing is uploaded, and the recording is deleted after each transcription.
- Do I need the internet at all for offline dictation?
- Only once, to download the speech model the first time — the same as installing any app. After that it works fully offline.
