What it does

11 shapes
Rectangle, rounded rectangle, circle, ellipse, decision, process, terminator, document, database, note and container: drag, resize, edit text, colours and borders.
Connectors that stay attached
Straight, elbow or curved, with arrowheads and labels. Drag a connector’s end to reconnect it; it follows shapes as they move.
Precise editing
Grid and snap, box selection, align and distribute, group into containers, bring forward or back, copy and paste, keyboard shortcuts, undo and redo.
Eight templates
Basic flowchart, sales pipeline, customer onboarding, org chart, software architecture, project approval, customer journey and decision tree.
Export and import
PNG (2×) and SVG images, and the native JSON file to keep a copy or move it to another browser.
Your documents
New, open, rename, duplicate and delete diagrams. Autosave in this browser with a visible save status.
Spatial view of the same diagram
One click turns the diagram into a 3D scene: layer groups stack as levels, clusters sit side by side, hierarchies rise. Orbit, zoom, select, edit labels and colours, move shapes and whole groups, collapse groups and fly between them; every change is the same document in 2D, with one undo history.
