Multicast

Multicast is a web app that lets people share presentations, videos and other content during online meetings. It sits alongside the meeting software rather than replacing it, so the content appears on the call as a shared screen.

What Multicast offers

• Presentation sharing — displays Google Slides presentations in a meeting.
• Virtual whiteboard — lets the presenter draw on a board and share it with attendees.
• Video sharing — plays YouTube videos and other clips into the call.
• Camera sharing — includes mirrored video and a fullscreen mode.

Who it works with

It is meant for anyone presenting over Zoom, Google Meet, Webex, Microsoft Teams or similar meeting tools.
