Why Echo for daily voice dictation
Designed for Daily Dictation
Buzz is excellent for transcribing files — but the workflow Echo is built for is different: press shortcut, speak, it types directly into your email, code editor, or document. This 'speak and it types' flow is Echo's core purpose.
Auto-Paste Into Any App
Echo's global shortcut triggers dictation and automatically pastes the result into whatever app has focus. No copy-paste step, no switching windows. Buzz doesn't offer this out of the box.
Voice Activity Detection + LLM
Echo automatically detects when you start and stop speaking using VAD, then optionally passes your transcription through a local LLM to clean up punctuation and remove filler words. Buzz requires manual recording controls.
