Mind Map
Visual brainstorming and idea organizer. Create nodes, connect ideas, and export your mind maps as PNG or JSON. Everything runs locally in your browser.
How to Create a Mind Map
Mind mapping transforms scattered thoughts into structured visual diagrams. This free online mind map maker lets you brainstorm, plan projects, and organize ideas without installing software or creating an account. Every node and connection stays in your browser, giving you complete privacy.
- Start with a central idea. When you open the tool, a root node labeled "Central Idea" appears. Double-click it to rename it to your main topic, project name, or question you want to explore.
- Add child nodes. Select the central node and click "+ Child" or press Tab. Each child represents a subtopic or branch of your main idea. Add as many levels as you need, up to 200 nodes total.
- Add sibling nodes. Select any node and click "+ Sibling" or press Enter to add a node at the same level. Use siblings for parallel ideas that share the same parent concept.
- Organize with drag and layout. Drag nodes to reposition them manually, or click "Layout" (or press L) to automatically arrange everything in a clean tree structure. Use "Center" (or press C) to bring the map back into view.
- Edit and refine. Double-click any node to edit its text. Use Ctrl+Z to undo mistakes. Delete unwanted branches by selecting a node and pressing Delete (removes all children too).
- Export your work. Click "PNG" to download a high-resolution image for presentations. Click "JSON" to save the raw data for later editing. Use "Import" to reload a previously exported JSON file.
Features
- Infinite Canvas with smooth pan and zoom using mouse wheel or touch gestures
- Auto-Layout arranges nodes in a clean hierarchical tree with one click
- Color-Coded Nodes automatically assigned from an 8-color palette for visual distinction
- Undo/Redo History with 40-step buffer so you never lose work
- PNG Export at 2x resolution using html2canvas for crisp images
- JSON Import/Export for saving, sharing, and restoring mind maps
- Auto-Save to localStorage so your map persists between sessions
- Keyboard Shortcuts for every action (Tab, Enter, Delete, F2, L, C, Ctrl+Z/Y)
- Touch Support for mobile devices with single-finger panning
- Offline Mode works without internet after initial page load
- Node Limit Badge shows current count vs. 200-node maximum
- Live Statistics displaying node count, connections, max depth, and data size
Use Cases
- Brainstorming Sessions. Start with a problem statement as the root node and branch out into potential solutions, constraints, and action items. The visual layout helps teams see connections they would miss in a linear list.
- Study Notes and Revision. Break down a textbook chapter into key concepts, definitions, and examples. The hierarchical structure mirrors how memory works, making recall easier during exams.
- Project Planning. Map out deliverables, milestones, dependencies, and team assignments. Export as PNG to include in project documentation or share with stakeholders who need a quick overview.
Tips and Tricks
- Keep nodes short. Use 2-4 words per node. Long sentences clutter the map and defeat the purpose of visual thinking. Add details in child nodes instead.
- Use the Layout button often. After adding several nodes, press L to auto-arrange. This prevents overlapping nodes and keeps the structure readable.
- Export JSON before clearing. If you want to start fresh but keep your work, export to JSON first. You can import it anytime to continue where you left off.
- Start with 3-5 main branches. Research shows that 3-7 top-level categories are optimal for comprehension. Add depth (children) rather than breadth (siblings) for complex topics.
- Use F2 for quick edits. Instead of double-clicking, select a node with a single click and press F2. This is faster when you need to rename multiple nodes in sequence.

Frequently Asked Questions
Can I save my mind map and come back later?
Yes. Your mind map is automatically saved to your browser's localStorage. When you return to the page, your nodes and connections are restored exactly as you left them. For a portable backup, export to JSON.
How many nodes can I add?
You can add up to 200 nodes per mind map. This limit ensures smooth performance across all devices including mobile phones. For larger maps, export and start a new branch in a separate session.
Is my data sent to a server?
No. Everything runs locally in your browser. No data is uploaded, stored on servers, or transmitted anywhere. The tool works completely offline after the page loads.
Can I share my mind map with others?
Export your mind map as JSON and share the file. The recipient can import it using the Import button. You can also export as PNG for a static image to share in presentations or documents.
What keyboard shortcuts are available?
Tab adds a child node, Enter adds a sibling, Delete removes the selected node, F2 edits text, Ctrl+Z undoes, Ctrl+Y redoes, L auto-layouts, and C centers the view. See the full shortcuts table above.
Does the mind map work on mobile devices?
Yes. The canvas supports touch gestures for panning and the toolbar buttons are fully tappable. For the best experience on small screens, use the zoom controls and Center button to navigate.
