Overview

Tetra dials into your calls — invite bot@asktetra.com from your calendar or start a call in the web app — and transcribes them automatically. Trained human editors then correct the automatic speech recognition, with no editor hearing more than 15 seconds of a call. Notes can be read, played back, searched, shared by link and exported to document tools.
