How it works
Start a board, share the link or QR code, and everyone draws on the same canvas. Up to four others can join.
What does touch the network
This tool is an exception to "nothing leaves your device". It contacts the public PeerJS service and Google's public STUN servers to connect browsers. They can see IP addresses and a random room ID, not your drawing, which travels directly between browsers.
Limits
- Nothing is saved. Closing the host's tab ends the session.
- If your connection drops, you are told, and further drawing stays local.
- Anyone with the link can join, so share it privately.
