Echosy is an macOS desktop app that captures system audio and microphone, transcribes speech in real-time using on-device ASR models (Qwen3-ASR, MLX Whisper, Whisper), and provides system-wide dictation — all running 100% locally. No cloud uploads, no subscriptions, no data collection. Your recordings, transcripts, and models live entirely on your machine.

Auto-save transcripts as Markdown, optional WAV recording
Export as .md or .txt, copy to clipboard
