Instant text,
absolute privacy.

A blazing-fast native desktop application that converts your voice into text and instantly injects it wherever you type. All entirely on your device by default.

Global Hotkey Workflow

Simply hold a global hotkey to record and release to transcribe. The text is seamlessly injected into your active application window, keeping you in the flow.

100% On-Device by Default

Zero data sent to the cloud. Audio and activity logs never leave your machine unless you explicitly configure optional online services via your own API keys.
