# Online meetings and webinars

Online events reach people wherever they are, but only if they can follow along. Line 21 adds live captions and translations to the meeting tools your audience already uses.

Send captions into Zoom or Microsoft Teams, let an AI call agent join and transcribe, or share a captions page that works next to any platform.

Covers: Zoom and Microsoft Teams calls, Webinars, Virtual events, Multilingual meetings.

## What makes it hard

**Captions inside the call**: Attendees expect captions in the meeting window, not in a separate tab they have to find.

**More than one spoken language**: Multilingual calls have several source languages, and every participant needs to follow all of them.

**No AV team**: Webinars are often run by one person who needs a setup that simply works.

## How Line 21 handles it

### Captions in Zoom and Teams

Send live captions into Zoom and Microsoft Teams with the meeting's caption token, so they appear in the meeting window.

### An AI call agent

A bot joins your Zoom call and transcribes it live, translating as it goes.

### Meetings in several languages

Meeting projects let each participant speak their own language and read everyone else in theirs.
