Think in diagrams.
An infinite canvas for 3D visualization, ReactFlow diagrams, D3 charts, and real-time collaboration — all in your browser.
A canvas that adapts to the work.
Switch between sketch, flow, and 3D without leaving the page. Every layer stays editable.
Sketch
Freehand drawing, sticky notes, and connectors. A whiteboard that gets out of the way.
Flowcharts
Flow diagrams, ERDs, and decision trees rendered with ReactFlow and exportable as SVG.
3D View
Switch any canvas into isometric 3D for spatial review of systems and floor plans.
Sketch-to-D3
Draw a chart, drop a data file, get back a working D3 visualization bound to your canvas.
Real-time collab
Multiplayer cursors and Yjs CRDT sync so every change is reflected across the team instantly.
Embed anywhere
Drop a canvas into Docs, Slides, or an external site with a single iframe snippet.
