About WebM transcription

Why WebM is different

Upload browser-recorded WebM straight from MediaRecorder, no re-encoding. We decode it streaming, so audio reaches the model without a round trip.

Typical use case

In-browser voice recordings, Chrome extension captures and embedded WebRTC meeting snippets that bypass native recorders entirely.
