Developer Mind Map
Create mind maps with keyboard navigation. Export to Mermaid syntax for documentation or PNG for presentations.
What is a Mind Map?
A mind map is a visual thinking tool that helps you organize information hierarchically. Starting from a central topic, you branch out into related subtopics, creating a tree-like structure that mirrors how our brains naturally associate ideas. It's perfect for brainstorming, planning projects, and documenting systems.
Why Use This Tool?
