AI-plus-human captioning, transcription and audio description at organizational scale
What it is
A media accessibility platform that produces captions, subtitles, transcripts and audio description for video, aimed at organizations with large or continuous video output — higher education, broadcasters, streaming platforms, corporate learning and events. Its pipeline uses automatic speech recognition and other AI as a first pass, combined with a predictive accuracy-scoring tool (Pulse) that flags which files most need human review, and human editors for final quality on files where it matters. Audio description is offered as human-voiced or AI-synthesized speech. Delivery integrates with 40+ platforms, an API, cloud storage and direct upload.
