Excaliself turns the Excalidraw canvas into your team's own whiteboard server, where every sketch, diagram, and flowchart lives in your database instead of a vendor's cloud. The home screen works like a file cabinet for drawings: nest them in folders, star the keepers, drag files between spaces, and find anything again by title or by the text inside the drawing. Share a link and teammates edit together in real time with live cursors and follow mode; links can stay members-only or open to guests who have no account at all. A shared Team space sits next to everyone's private space, and one team library holds the shapes and icons the whole group reuses. AI clients can join with a personal access token: Claude Code or Claude Desktop can search your drawings, read what a diagram says, and create new ones from shapes or a Mermaid flowchart. Accounts are invite-only, single sign-on covers Google, Microsoft, and any OIDC provider, and admins manage members, roles, and password resets from Settings. Deleted drawings rest in a trash folder for thirty days before they are purged, and everything auto-saves as you draw.
