Whiteboards
Collaborative canvases for sketches and diagrams.
Whiteboards are infinite collaborative canvases scoped to a repository (G W): architecture sketches, incident timelines, planning sessions, anything that wants boxes and arrows rather than paragraphs.
Create a whiteboard
Create from the whiteboards page, name it, and start drawing. Whiteboards list alongside docs and collections, and they rename and delete the same way.
Drawing together
The canvas gives you shapes, arrows, free-hand drawing, and text. Collaboration is live at the element level: you see teammates' cursors, and two people moving different shapes at once both win. It is the same kind of multiplayer as the document editor, applied to a canvas.
A whiteboard is where a design discussion starts; the doc is where its conclusion gets written down. Keeping both in the repository means the sketch and the decision stay next to the code they shaped.
