Mind Map

Branch ideas out from a central topic, drag and color every node, then auto-layout the whole map as a tree or radial burst. It all lives entirely on your device, nothing is uploaded.

Your maps are saved only in this browser (localStorage) and never uploaded.

A keyboard-first mind map that stays on your machine

Start from a central idea and grow branches with Tab and Enter, every branch gets its own color automatically, and you can recolor, drag, collapse or delete any subtree. One click tidies the whole map as a left-to-right tree or a radial burst, and you can pan, zoom and fit the canvas freely. Keep as many maps as you like, undo anything, and export a crisp 2× PNG, a JSON backup or a plain-text outline. No account, no server, completely free and private.

About Mind Map

Mind Map is a free, private productivity tool that runs entirely in your web browser. Brainstorm on an interactive mind map: add, drag, color and collapse nodes, then export as PNG, JSON, or a plain-text outline. Because everything happens locally on your device, your files and data are never uploaded to a server, there is no sign-up or installation required, and it keeps working offline. It is handy for brainstorming, project planning, note-taking, and visual thinking. Like every free online tool by Digital Heroes, Mind Map is 100% free with no limits.

What you can do

Build a mind map from scratch in seconds, starting from a central topic you name yourself.

Add child and sibling nodes with Tab and Enter, then rename them inline with a double-click or F2.

Auto-layout the whole map as a left-to-right tree or a radial burst with one click.

Color entire branches by selecting any node and choosing a color, which cascades to all children.

Collapse subtrees to hide detail, and drag any node (with its whole subtree) to reposition it.

Export your map as a crisp 2x PNG, a JSON backup you can re-import, or an indented text outline.

How to use Mind Map

Open Mind Map in your browser. No signup, no install.

Click the central topic node and type your idea. Press Tab to add a child branch, Enter to add a sibling.

Click Download PNG, Export JSON, or Outline .txt to save your map. Your data stays on your device.
