How does on-device Whisper speech-to-text operate without server upload?

It executes OpenAI Whisper models directly on your CPU/GPU threads via WebGPU. Speech is transcribed locally with integrated voice activity detection (VAD).

Which subtitle and transcript formats can I export?

You can export SRT subtitle files with precise millisecond timestamps, WebVTT files for video players, or clean plain text.

Are my confidential meeting recordings and voice memos secure?
