The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
