Engineers sketch services and the failure paths between them, designers lay out screens and the flow through them, teams put every half-formed idea somewhere everyone can see it. Then somebody presents the result to a room, and a teacher runs a lesson a class joins from a link. It is the same infinite canvas underneath, so the only real question is which job you are hiring it for.
Sketch services, queues and failure paths fast enough to keep up with the argument, then export the diagram into the design doc.

Lay out screens rough enough to keep the review on the flow, join them with arrows, and hand the result over as a link or a PNG.
See how
Send a link, get everyone drawing in the same place, then lasso the ideas into clusters and walk the outcome before people leave.

Turn the board you already have into slides, run it fullscreen with the camera flying between them, and keep whatever you drew on the way.

Send one link and the class is on the board, drawing or watching, with nothing to install and no accounts to create.

Free to start and free to keep using: unlimited boards on your device and one cloud board for syncing and sharing, no card required. The free tier is not a time-limited trial.
Local-first and offline: boards live on your device by default and keep working with no connection, and cloud sync is optional and per board.
Guests arrive from a link with no account, as an editor who can draw or a viewer who can only watch, and the board is encrypted in your browser before anything is uploaded.
