Frequently asked questions

Is my voice data sent to the cloud?

No. Transcription happens 100% on your device using Whisper AI. Your audio never leaves your computer—we don't have servers to send it to even if we wanted to.

What about accents?

Mumbl uses OpenAI's Whisper model, which was trained on 680,000 hours of multilingual audio. It handles most accents and even multiple languages remarkably well.

Mac only?

Nope! Mumbl is available for both macOS and Windows. Download whichever version you need from the download page.

How is this different from built-in dictation?

Built-in dictation just transcribes what you say. Mumbl goes further—it cleans up your speech, removes filler words (um, uh, like), fixes grammar, and formats it in your chosen style.

Is there a free tier?

Yes! You get 10 free transcriptions per week, forever. No credit card required. If you need more, you can upgrade to unlimited for $10/month or $60 one-time for lifetime access.

Need Mumbl for your team?

Deploy across your organization with per-seat licensing. Each installation runs independently on the employee's device. No shared servers, no centralized data store, no breach vector.
