Privacy

Where your audio and screen go

Wispr Flow's privacy policy says transcription always happens in the cloud. (Source: Wispr Flow privacy policy) Its security FAQ says the service processes and stores customer data in the United States. (Source: Wispr Flow Help Center: Security and compliance FAQ) Its Context Awareness feature is on by default and, according to its help center, can send app info, textbox contents, on-screen text and a screenshot along with a dictation. You can switch it off in Settings › Data and Privacy. (Source: Wispr Flow Help Center: Context Awareness)

SayWrite has no cloud step to configure. NVIDIA Parakeet TDT 0.6B v2 runs on your Mac's Neural Engine, the temporary recording is deleted as soon as it's transcribed, and SayWrite never captures your screen. AI Polish runs on Apple's on-device model or on a server you run at 127.0.0.1, and SayWrite refuses any other address.

The full breakdown, including the only three network connections SayWrite makes, is on the security page.

Connectivity

Offline use

Because SayWrite's speech model lives on your Mac (a one-time download of about 465 MB), dictation keeps working on a plane, in a basement or on a locked-down network. Try it yourself: turn off Wi-Fi, hold Fn and talk. Wispr Flow's cloud transcription needs a connection (Source: Wispr Flow privacy policy).

Price

Price: free during early access vs $12–15 a month

Wispr Flow's free plan has a weekly word limit of 2,000 words on desktop. Pro is $15 per user per month, or $12 billed annually, and Growth is $23, or $18 billed annually. (Source: Wispr Flow pricing)

SayWrite is free during early access, with no word limit, no account and no credit card. If that ever changes, it'll be announced on the changelog first.

AI Polish

AI cleanup: whose model?

Hold Fn and tap Space while you talk, and SayWrite's AI Polish turns a ramble into what you'd have written with time. It uses Apple Intelligence's on-device model on macOS 26, or a model you run yourself in Ollama or LM Studio. You pick the model, and it runs on your hardware.

Switching

How to switch from Wispr Flow

  1. Download SayWrite, allow Microphone and Accessibility access, and download the speech model.
  2. Quit Wispr Flow so only one app listens to the Fn key, and set System Settings › Keyboard › “Press 🌐 key to” to Do Nothing.
  3. Hold Fn to talk, or tap it to start and stop. Tap Space while holding Fn to Polish.
  4. Add names and jargon to the personal dictionary, and recreate your snippets as voice snippets.
  5. Optional: turn on per-app auto-polish for Slack or Mail so every dictation there is tidied automatically.
