Model Brief is made by the same people as Inmost, one of the six products below. We sell it, so do not take our word for the privacy claims: every row links to the page it came from.
Five of the six tools here can recognise speech on your own machine. Wispr Flow cannot. It transcribes on its servers, and its data-controls page says so in one line: "Transcription always occurs on the cloud."

| App | Platform | Price | Audio leaves the machine |
|---|---|---|---|
| Inmost | macOS 14+, Apple Silicon | $39 once | No |
| Superwhisper | Mac, Windows, iOS, Android | Free; Pro $8.49/month, $84.99/year, $249.99 once | Only if you pick a cloud model |
| MacWhisper | Mac | Free; Pro €65 | No, on the local models |
| Wispr Flow | Mac, Windows, iOS, Android | Free; Pro $15 per user/month | Yes, always |
| Apple Dictation | macOS, iOS | Free, built in | Sometimes; Settings says which |
| Windows Voice Access | Windows 11 | Free, built in | No, after the language download |
The three price models
One payment: Inmost at $39 and Superwhisper's $249.99 lifetime licence. Subscription: Wispr Flow at $15 per user a month, Superwhisper at $8.49 a month or $84.99 a year. Free with a paid tier on top: MacWhisper's €65 Pro, and every product's free plan.
What the table hides
Apple Dictation is the one that depends. Apple's Mac guide says to check Keyboard settings for whether your voice is processed on the device or sent to Siri servers, so the answer varies by language and Mac.
Windows Voice Access works without a connection, but only after a one-time download: Microsoft's setup page says the language files arrive over the internet first.
Superwhisper's free tier runs small Whisper models locally. Its paid tiers add larger models and the option to send audio to a cloud provider with your own key, which moves that row into the other column.
Where Inmost sits
Inmost runs recognition on the Mac, keeps no account, and uploads no audio. It is $39 once, macOS 14 or later, Apple Silicon only. There is no Windows build and no iPhone app, and no date for either.
