Private dictation for macOS
Private dictation for Mac, where your voice never leaves the device
Private dictation means your speech and the text it becomes stay on your own computer. Dictro's default on-device mode runs recognition and language cleanup locally on Apple Silicon—no audio uploads, no transcript sent, and nothing used to train a model.

A clear definition
What “private dictation” actually means
Turning speech into text touches four things that can leak: the raw audio, the transcript, whether either is retained, and whether your words are used to train a model. Dictation is only truly private when all four stay under your control. Many tools describe themselves as secure while still streaming your audio to a server to transcribe it— convenient, but your voice has left the device.
Your audio
The recording of your voice. Private dictation transcribes it on your Mac instead of uploading it.
Your transcript
The text you dictated. It should land in your app, not be copied to a service along the way.
Retention & training
Nothing kept on a server, and nothing fed into model training without your explicit choice.
Privacy by architecture
How Dictro keeps dictation private
Dictro's on-device mode is the default, and it is private because of how it is built rather than because of a policy promise. Speech recognition runs on the Apple Neural Engine and the language cleanup pass runs locally on the GPU. The finished sentence is placed directly into the text field you were already using. Your audio is never uploaded, no transcript is sent to Dictro, and your words are not used for training.
- Speech and language models run on your Apple Silicon Mac, not a server.
- The core workflow keeps working with Wi-Fi switched off.
- The result goes straight to your cursor—Dictro does not keep a copy.
- Transcript history is off by default and, if enabled, stays on your Mac.
Three approaches compared
Private on-device, cloud, and built-in dictation
The privacy difference is not about the app's marketing—it is about where the audio is transcribed. This is the question worth asking of any dictation tool before you trust it with sensitive writing.
| What happens to your voice | Dictro (on-device) | Cloud dictation apps | Built-in macOS |
|---|---|---|---|
| Audio transcribed on your Mac | Yes, by default | No—streamed to a server | Sometimes, depends on settings |
| Works with Wi-Fi off | Yes | No | Depends on Mac and language |
| Transcript sent to a service | No, in on-device mode | Typically yes | Depends on mode |
| Cleans up filler and structure | Local refinement pass | Varies | Mostly literal |
| Cloud is opt-in, not default | Yes (Fast Mode) | Cloud is the product | Not clearly separated |
Trust, then test
Verify private dictation yourself
You do not have to take privacy on faith. Because on-device mode needs no server, you can prove it with a two-minute test.
- 1
Select on-device mode
Confirm Dictro is set to the local, on-device mode before you start.
- 2
Turn off the network
Switch Wi-Fi off from Control Center and disconnect any wired connection.
- 3
Dictate into a local app
Place the cursor in Notes, hold Right Option, speak a sentence, and release.
- 4
Confirm the result
If the cleaned sentence appears with no connection, recognition and refinement ran entirely on your Mac.
Your choice, made visible
Fast Mode and transcript history are opt-in
Dictro starts fully private. An optional Fast Mode can use cloud processing for people who prioritize speed and turn it on themselves— it is separate and off by default. Transcript history works the same way: it is disabled unless you enable it, and any notes it keeps are stored only on your Mac and never uploaded or used for training.
For the exact details on account data, usage counts, retention, and Fast Mode, read Dictro's privacy policy. To see how the same local design keeps working without a connection, read the offline dictation guide, or visit the Mac dictation app overview for the full workflow.
Frequently asked questions
What people ask about Dictro
What is the most private dictation app for Mac?
The most private option processes your speech entirely on your own Mac, so audio and transcripts never reach a server. Dictro's default on-device mode does this on Apple Silicon: recognition and language cleanup run locally, no audio or transcript is uploaded, and your words are never used for training.
Is voice dictation on a Mac private by default?
It depends on the tool. Many dictation apps—and macOS built-in dictation in some configurations—send audio to a server to transcribe it. That is convenient but means your voice leaves the device. Dictro's on-device mode keeps the entire pipeline local, so private dictation is the default rather than an add-on.
Does Dictro send my voice or transcript to the cloud?
Not in the default on-device mode. Audio capture, speech recognition, and refinement all run on your Apple Silicon Mac, and the finished text goes straight into your text field—Dictro does not receive a copy. An optional Fast Mode can use cloud processing, but it is off until you deliberately turn it on.
Is Apple's built-in Mac dictation private?
It can be, but not always. Depending on your Mac, language, and settings, built-in dictation may send audio to Apple's servers for transcription rather than processing it fully on-device. If keeping every word local matters to you, verify the mode rather than assuming, or use a tool like Dictro that is on-device by default.
Can I use private dictation offline?
Yes. Because Dictro's on-device mode needs no server, it keeps working with Wi-Fi off—on a plane, on a restricted network, or anywhere else. Private and offline come from the same design: the models live on your Mac.
