Line 21 is a handy tool that helps create, improve, translate, and deliver live captions.

It combines the skills of human captioners with AI''s proofreading abilities. This makes live content more accessible and of higher quality.

Key Features

AI Proofreader

Line 21''s AI Proofreader fixes errors in captions right away. It has different trust modes to fit various user needs.

Advisor suggests corrections that humans can approve.
Assistant helps writers during live events by making edits that can be changed if needed.
