Media files stay local; diagnostics are separate. Your media file is processed in your browser and is not uploaded or sent to an AI service. If enabled, anonymous diagnostics may be sent, but they do not contain file contents.

Processing Architecture & Calibration

拖放音频文件一键转录为文本 All media streams are isolated locally inside your device using hardware-accelerated WebAssembly (WASM) and WebCodecs. Zero bytes of audio or video content are ever transmitted to external cloud servers.

How It Works

  1. Drop your audio or video file directly into the browser dropzone.
  2. The client-side engine executes local inference or bit-exact extraction without upload delays.
  3. Audition the 15-second realtime A/B comparison with the Dry/Wet slider.
  4. Export your pristine clean master file with 100% original video track preservation.
