Which Mac dictation apps work offline and keep your audio private?
Short answer: several apps transcribe without an internet connection, but working offline and keeping your audio private are two different questions, and an app can pass one while failing the other. This is a filtered round-up read through those two lenses, with a test you can run yourself in thirty seconds. The category background sits in the guide to local speech-to-text on Mac; start there if you want the how-it-works before the which-app.
The two questions are not the same
Works offline asks: does the app function with no internet connection? That is a question about where the speech model runs. If the model is on your Mac, the app works on a plane; if the model is in a data center, it does not.
Keeps audio private asks something narrower: do the audio and the transcript both stay on the device? An app can run the speech model locally, so it works offline, and still send the finished transcript to a cloud LLM the moment you turn on an AI cleanup or summarize feature. That is a second leg of the same data, and it is where most of the confusion lives. The framing for why both legs matter is in what on-device speech recognition is.
The apps, filtered
| App | Works offline? | Audio stays on Mac? | The catch |
|---|---|---|---|
| Parakeety | Yes | Yes, always | No cloud path at all; no AI cleanup to leak the transcript |
| Apple Dictation | Usually | Usually | On-device only on supported languages and newer Macs; some cases still use the server |
| MacWhisper | Yes (local models) | Yes for transcription | AI summarize features send the transcript to a cloud LLM |
| SuperWhisper | Depends on model | Depends on config | Cloud model options and AI cleanup both send data out |
| VoiceInk | Yes (local models) | Yes for transcription | Optional AI enhancement can route text to a cloud model |
| Talon Voice | Yes | Yes | Voice control system, not a plain dictation app; real learning curve |
| Wispr Flow | No | No | Cloud service; audio uploads to servers; enterprise tier adds a BAA, not local processing |
| Aqua Voice | No | No | Cloud service; does not function without connectivity |
The ones that pass both tests
Parakeety is on-device by architecture, with nothing to configure. It runs Parakeet TDT v3 on the Apple Neural Engine and contains no other data path: no cloud model to fall back to, no AI cleanup to send the transcript anywhere. Both legs stay on the Mac every time.
Apple Dictation is free and on-device for many languages on modern Apple Silicon, which makes it a genuine option for casual use. The caveat is that the on-device guarantee is uneven: it varies by language and by Mac generation, and some cases still reach the server. The detail is in does Apple Dictation work offline.
Talon Voice runs its speech engines on-device and the accessibility community relies on it working offline. It is a full voice-control system rather than a plain dictation app, so it earns a place here on privacy but comes with a setup cost; see does Talon Voice work offline.
The ones that are local until you turn on the AI features
MacWhisper and VoiceInk both transcribe locally with Whisper or Parakeet models, so the audio leg stays on the Mac. The catch is the same for each: the AI features that summarize or reformat the transcript call out to cloud LLM providers. Leave those off and the transcript stays local too. See is MacWhisper on-device.
SuperWhisper is the hybrid case. Its model picker includes local Whisper variants (offline, private), cloud model options (online, not private) and AI cleanup (sends the transcript out regardless of the speech model). Whether it passes both tests depends entirely on the configuration; the full breakdown is in is SuperWhisper on-device.
The ones that fail: cloud by design
Wispr Flow and Aqua Voice are cloud dictation services. The speech model runs in a data center, so the audio leaves your Mac and the app does not work without a connection. That is not a flaw, it is the design; it buys broad language coverage and server-side features. For regulated work, Wispr Flow’s enterprise tier adds a Business Associate Agreement and Zero Data Retention, but that is contractual privacy, not architectural: the audio still leaves the device. The distinction is worked through in architectural vs contractual privacy.
Test any app yourself: the Airplane Mode check
You do not have to take a vendor’s word for it. Two quick checks settle both questions:
- Turn on Airplane Mode (or pull the Ethernet cable and switch off Wi-Fi) and try to dictate. If the text still appears, the speech model is running on your Mac. If it fails or hangs, it needs the cloud.
- With the network back on, check the AI features. Any feature that rewrites, summarizes or cleans up your transcript is the one to scrutinize, because those usually route text to a cloud LLM even when the audio path is local. If the app has none, or you can switch them off, the transcript leg stays local too.
An app that passes both is private in the sense that matters: nothing you say and nothing it writes leaves the machine.
How to choose
- You want both legs local with nothing to configure, in English or a European language. Parakeety.
- You dictate casually and it is already on your Mac. Apple Dictation, accepting the language and Mac-generation caveats.
- You mainly transcribe recordings and will keep the AI features off. MacWhisper or VoiceInk.
- You need non-European languages or a cloud compliance path and accept audio leaving the device. Wispr Flow, enterprise tier.

FAQ
- Which Mac dictation apps work fully offline?
- Parakeety, Apple Dictation in supported languages on Apple Silicon, and the local-model paths of MacWhisper, SuperWhisper, VoiceInk and Talon Voice all transcribe without an internet connection. Cloud services like Wispr Flow and Aqua Voice do not work offline at all, because the speech model runs in a data center.
- Does working offline mean my audio is private?
- Not automatically. Offline means the app functions without internet. Private means both your audio and the resulting transcript stay on the device. Most local apps keep the audio on the Mac but will send the transcript to a cloud LLM if you turn on AI cleanup or summarize features. Parakeety has no such feature, so both the audio leg and the transcript leg stay local.
- How can I tell if a dictation app is really on-device?
- Turn on Airplane Mode and try to dictate. If it still transcribes, the speech model is running locally. If it fails or hangs, it needs the cloud. Then, separately, check whether any AI cleanup or summarize feature sends the transcript out even when the audio path is local. Both legs have to stay on the Mac for the app to be private, not just the audio one.
- What is the most private Mac dictation app?
- Of the apps that run entirely on-device, Parakeety has the smallest privacy surface: one Parakeet TDT v3 model on the Apple Neural Engine, no AI post-processing, no cloud features behind toggles. There is no data path out of the app, so there is nothing to configure to make it private and nothing to switch off.
Try it
Parakeety passes the Airplane Mode test by design: it runs Parakeet TDT v3 on the Apple Neural Engine, with no cloud path and no AI cleanup feature to send the transcript anywhere. Hold the section key, talk, release; your words paste at the cursor in whichever app you were typing into, and nothing leaves the machine. It needs Apple Silicon and macOS 14 or later. There is a free 7-day trial with no card required. After that it is $30 once.
