Excalidraw
Free AI whiteboard that turns prompts into hand-drawn diagrams.
Excalidraw is a free, open-source virtual whiteboard for sketching hand-drawn-style diagrams, flowcharts, wireframes, and mind maps — now supercharged with an AI assistant that turns plain-text prompts into editable diagrams in seconds. Real-time collaboration, end-to-end encrypted live rooms, infinite canvas, exportable to PNG/SVG, and a beloved sketchy aesthetic make it a go-to tool for engineers, designers, teachers, and product teams. Completely free to use in the browser with no signup required.
