Mind Map — free browser mind mapping tool

What this mind map is for

A free, in-browser tool for brainstorming, outlining and structuring ideas. Capture a central topic, branch it into sub-ideas, and keep going until the shape of the problem is clear. Nothing leaves your device — the whole map is saved in your browser's local storage.

Parent / child structure

Mind maps work outward from a root idea. Start with one node for the central topic. From there, build parent → child relationships: each child is one level more specific than its parent. Children of a "Marketing" node might be "SEO", "Email", "Social". Children of "SEO" might be "On-page", "Off-page", "Technical".

• Add a node with Add node or by double-clicking empty canvas.
• Add a child by selecting a node and pressing Tab (or the + Child action).
• Drag any node to rearrange — the lines redraw automatically.

Linking nodes (non-parent relationships)

Not every connection is parent-to-child. Two siblings might depend on each other; an idea in one branch might reference an idea in another. Use Link mode to draw a relationship line between any two nodes without changing the hierarchy.

• Select a node, click Link, then click the target node.
• Use this for dependencies, "see also" pointers, or cross-branch ideas.

Notes and details on a node

Node labels stay short and scannable. For anything longer — quotes, source links, a paragraph of context — open Notes on the selected node. Notes are stored with the node but never rendered on the canvas, so the map stays clean.

Import and export

Your map is autosaved locally, but local storage can be cleared. To keep a backup or move a map between devices:

• Export downloads the full map (nodes, links, positions, notes) as a JSON file.
• Import loads a JSON file or pasted JSON. Importing replaces the current map, so export first if you want to keep it.

Keyboard shortcuts

• Enter edit selected node · Tab add child · L link mode · N open notes · Del delete node.
• + / − zoom · 0 reset view.
