A mind map is a visual thinking tool developed by British psychologist Tony Buzan in the 1970s. It organizes ideas, concepts, tasks, or information in a radial branching structure around a central theme, using colors, images, and keywords to enhance memory and comprehension.
• One Central Theme: Every mind map has a single central topic placed in the middle of the page
• Thick Main Branches: Primary branches radiating from the center should be thicker to convey hierarchy
• Keywords, Not Sentences: Each node should contain only a keyword or phrase, not a full sentence
• Visual Elements: Use colors, icons, and images strategically to strengthen memory
• Free Association: Leave enough space between branches for future additions and divergence
• Study Notes: Structure textbook knowledge to improve memorization and recall
• Brainstorming: Collect and organize ideas quickly during team sessions
• Project Management: Decompose projects, track tasks, and manage dependencies
• Presentation Outlines: Build logical speech frameworks without missing key points
• Book Summaries: Distill book content into structured knowledge graphs
This free online mind map tool is easy to use with no registration required. Here is the detailed guide:
Create Nodes: Select any node and click the "Add Child" button or press the Tab key to add a child node. New nodes are automatically placed to the right of the parent with a connecting line. A root node exists by default—start branching from it.
Edit Node Text: Double-click any node to enter edit mode, type your content, and press Enter to confirm. Keep node text short and keyword-focused to follow mind mapping best practices. Press Escape to cancel editing.
Move Nodes: Select a node and drag it freely. The connecting lines update automatically. Arrange nodes at the same level horizontally and expand levels vertically for a clean structure.
Delete Nodes: Select an unwanted node and click "Delete" or press the Delete key. Note: deleting a parent removes all its descendants—use with caution.
Export & Share: When finished, export a high-resolution PNG for presentations or social sharing, or export JSON to save your data for later editing. The import feature restores complete maps from previously exported JSON files.
Mind maps are widely used in modern work and learning. Here are a few typical scenarios:
Boost Learning Efficiency: Facing fragmented knowledge, mind maps help learners build frameworks and connect scattered information. For example, when learning programming, use a mind map to organize language features, common libraries, and best practices. Research shows that students using mind maps perform 10–15% better on information recall tests than those using linear notes.
Team Brainstorming: During product planning or creative sessions, a mind map is a powerful way to collect and organize ideas. The facilitator sets the topic as the central node, team members contribute ideas as branches, and the group restructures them into a clear plan. Compared to linear notes, mind maps let everyone see the big picture and reduce missed details.
Complex Project Breakdown: When tackling large projects, project managers can use mind maps to decompose goals into phases, tasks, and subtasks, assigning owners and deadlines to each node. This visual WBS (Work Breakdown Structure) is more intuitive than tables and makes it easier to identify critical paths and risks.
Mind Map vs Concept Map: Many people confuse mind maps with concept maps. A mind map is radial with a single central theme and hierarchical branches; a concept map is a network where nodes can have multiple connections with labeled relationships (e.g., "causes", "is a"). Mind maps are better for creative ideation; concept maps excel at showing complex causal relationships.
Advantages of Digital Mind Maps: Compared to hand-drawn maps, digital tools are editable, searchable, shareable, and exportable. This tool supports JSON export, so you can sync maps across devices or integrate with other tools like Notion or Obsidian.
Related Tools: If you need advanced collaboration, try XMind, MindNode, or Lark Docs. However, this tool’s strength is zero registration, zero installation, and full client-side privacy—perfect for quick notes and temporary use.
No. All data is processed locally in your browser and never uploaded to any server. You can export a JSON file to save your work locally, then import it later to continue editing.
The tool supports exporting as a high-resolution PNG image and as a structured JSON file. PNG is ideal for presentations, documents, or sharing; JSON is perfect for backups and re-editing.
There is no hard limit. Performance depends on your device. A typical computer can handle hundreds of nodes smoothly. For the best experience, we recommend keeping a single map under 200 nodes.
Multi-selection is not supported in the current version. Please operate nodes one at a time. Batch operations may be added in future updates.
Yes. The tool is responsive and works in mobile browsers. However, due to smaller screen sizes, we recommend using a tablet or desktop for the best experience.
The current version uses uniform curved lines. Future versions may include straight, elbow, and dashed line styles along with custom colors.
The current version supports text nodes only. Future updates will add support for emojis and simple icons to enrich your maps.
Undo is not yet available. We recommend exporting JSON backups regularly. Save a backup before deleting important nodes.
