How Rev AI Works
Access Rev AI through the web dashboard or directly via the REST API. Upload audio or video files for asynchronous transcription, or connect a streaming audio source for real-time speech-to-text. Rev AI's ASR engine processes content and returns a detailed JSON transcript with timestamps, speaker labels, and confidence scores for every word. Review and edit results in the online transcript editor. Export in formats including SRT, VTT, TXT, DOCX, and JSON. Developers integrate Rev AI into custom applications using the well-documented SDK in Python, Node.js, Go, and other languages. For maximum accuracy on critical content, Rev AI also offers human transcription through the Rev marketplace with guaranteed accuracy levels.
