Drawing tools
Sketch on an Excalidraw whiteboard or create structured diagrams with diagrams.net. Keep local projects, start from templates, and download portable backups.
Choose the right drawing tool
Use Whiteboard for freehand notes and brainstorming, or Diagram Editor for connected shapes and flowcharts. Both use the browser window for editing. Diagrams.net loads externally; project storage stays in this browser and does not sync across devices.
