## What we do

AI made multilingual live events affordable, and now organisers want them in ten languages at once, with captions and dubbing, on every platform. Generic AI stumbles on names and jargon, and nothing joins the pieces together.

Line 21 orchestrates speech recognition, translation and voice models alongside human captioners, and delivers the result to venue screens, streams and meeting platforms in real time.

Two technologies sit at its core: an AI Proofreader that checks every caption line against a glossary built for each event, and a cloud video encoder that puts captions into live streams on any platform.
