Voice Transcription Reimagined

The Art of
Transcription

A desktop companion that listens when you speak and writes when you stop. Elegantly simple. Fiercely private. Remarkably fast.

We believe transcription should be invisible. Press a key, speak your mind, and watch your words appear. No windows. No clicks. No waiting. Just your voice, transformed.

Three Pillars: Experience, Performance, Privacy

Chapter I

Core Principles

The Workflow

A single global hotkey is all you need. Hold to record, release to transcribe. Your text appears in whichever application has focus.

The Speed

Written in native code for performance that online services cannot match. GPU acceleration takes it even further.

The Promise

Every transcription happens on your machine. Your audio, your logs, your data --- never shared without your explicit consent.
