Core Features

Hold. Speak. Release.

Global hotkey activation turns speech into text and injects it directly into your active application. No copy-paste. No switching windows. Just speak.

Privacy by Design

Everything runs on your machine. Audio recordings, activity logs, transcription data — none of it leaves your device unless you explicitly choose otherwise.

Native Speed

Written in native code. GPU-accelerated where available. Transcribes 30 seconds of speech in 1.5 seconds. No Python runtime. No Electron.

Total Control

Select speech models, configure backends (auto/CPU/GPU), set up online providers with your own API keys, and route through LLMs like Gemini Flash for extreme accuracy. Every detail is configurable.
