Developer Mind Map

Docs

Create mind maps with keyboard navigation. Export to Mermaid syntax for documentation or PNG for presentations.

Better on a larger screen

I respect your commitment to mobile productivity, but this tool works best on a laptop, tablet, or desktop for comfortable node editing and navigation.

13 nodes • 12 connections • Auto-saved

How It Works

This mind map tool combines keyboard-driven efficiency with AI-powered expansion. Start with a template or blank canvas, use keyboard shortcuts to rapidly build your structure, and let AI generate sub-concepts for any node. Your work auto-saves to the browser, so you can close the tab and pick up exactly where you left off.

What You Get

  • AI Expansion — Select any node and click AI Expand to generate 4-6 relevant sub-concepts
  • Ready-Made Templates — Start with System Architecture, Startup MVP, User Journey, or Demo
  • Undo/Redo History — Full history tracking with Ctrl+Z and Ctrl+Shift+Z shortcuts
  • Depth-Based Styling — Nodes automatically color-coded by hierarchy level
  • Animated Connections — Flowing edges with arrows show data direction
  • Fullscreen Mode — Distraction-free editing for complex maps
  • Multiple Exports — Download as JSON, PNG image, or copy Mermaid syntax
  • Persistent Storage — Auto-saves to localStorage, survives browser restarts

Common Use Cases

System Architecture

Map microservices, APIs, and data flows. Use AI to expand components into detailed specs.

Brainstorming Sessions

Rapid idea capture with keyboard shortcuts. AI helps explore directions you haven't considered.

Project Planning

Break down features into epics, stories, and tasks. Export to JSON for tooling integration.

Documentation

Export to Mermaid for GitHub READMEs, or PNG for presentations and wikis.

Mermaid Export

Mermaid is a diagramming language supported by GitHub, GitLab, Notion, and most documentation tools. Click "Copy Mermaid" to get syntax that renders your mind map anywhere:

mindmap
  root((Main Topic))
    Branch 1
      Sub-item
    Branch 2
      Sub-item

Privacy

Your mind map data is stored locally in your browser. The only external call is when you use AI Expand — the selected node's text is sent to generate sub-concepts, then immediately discarded. Nothing is stored on our servers or used for training.
