Simultaneous screen sharing

Multiple users can share any app window by drag & drop and by floating tabs above each window.

Multi-user mouse & keyboard

Anybody can move, click, and type into any shared app at the same time with near-realtime latency.

Multi-user copying & pasting

Copy & paste content across each other's windows. Mary can copy content from Alice's window and paste it into Bob's.

Audio & video chat

Talk to each other and see other with a single click by simply unmuting yourself.
