Interactive mind map with drag, undo, save JSON, export PNG / PDF.
Brainstorm and structure ideas with an interactive mind map. Click to add child nodes, drag to rearrange, edit node text inline, set colors per branch, collapse / expand sub-trees, undo / redo, and zoom & pan the canvas. Auto-layout keeps everything tidy. Save your map as JSON for later editing, export as PNG image, or as printable PDF. All data stays in your browser.
