What it does

  1. Captions page

    Every project has a shareable page at no extra cost. Viewers choose their language; you set the colours, fonts and size. Show it on a venue screen or share a QR code.

  2. Overlay

    A floating, borderless window from the Line 21 app that puts captions on top of slides or any other application.

  3. Zoom, Teams and YouTube

    Send captions as text into Zoom and Microsoft Teams with the meeting's caption token, or to YouTube Live through its caption ingestion URL.

  4. Encoded into the stream

    Closed captions inside your RTMP stream, simulcast to YouTube, Twitch, Facebook and other platforms.

  5. HLS player

    Your video with a caption track for every language, in our player or yours.
