Is there a free speech-to-text app for Mac?
Yes. Mellon is a free speech-to-text app for Mac that runs entirely on your device. No signup, no payment, no limits. Your voice stays on your Mac—we never collect or process it on our servers. It works offline and in every app you use.
Why is Mellon free?
We believe everyone deserves access to fast, private voice-to-text. Mellon runs entirely on your Mac—no cloud, no subscriptions, no data collection. We're building tools we want to exist in the world, and making them free is part of that vision.

Which macOS versions are supported?
Mellon works on macOS 12 (Monterey) and newer. We recommend running the latest macOS version for the best experience.
How is Mellon different from built-in macOS dictation?

Mellon also offers better accuracy, custom shortcuts, and works universally across all apps. It's the best dictation app for Mac users who want privacy and speed.
Do you support languages other than English?
Currently, Mellon supports English with high accuracy. We're working on adding support for Spanish, French, and German in future updates.
