Echo turns your voice into clean, editable text in real time
Fast first token, stable live output, accurate final text
Echo = fastest path from thought to editable text
Typing is precise but slow. Pure voice is fast but hard to control. Echo combines the best of both: the speed of speaking, the clarity of text, and the control of editing. We believe the future of human-computer interaction is not binary—it's fusion.
Words appear as you speak, with millisecond latency. Supports Deepgram, Volcano, and more with intelligent routing.
From pure transcript to deep polish, five preset modes. Smart Polish balances speed and quality; StreamFast prioritizes speed.
Deepgram, ByteDance Volcano, OpenAI Whisper with intelligent routing.
