Answers for people searching for a simple browser whiteboard, online collaborative drawing tool, or tablet-to-browser sketch workflow.
What is Dual Canvas?
Dual Canvas is a browser-based collaborative whiteboard for drawing, sketching, and simple diagramming with a share link or session code.
Can I draw on a tablet and show it in a browser?
Yes. Open the same session on your tablet and another browser screen, then draw with pen, line, and rectangle tools while viewers see updates in real time.
Do participants need to install an app?
No. Dual Canvas runs in the browser, so participants can join with a link or code without installing a separate whiteboard app.
