Why use this mind map generator
Structure at a glance
A tree from one central topic out to concepts and sub-ideas. You see how the pieces fit, not just a list.
Built from your source
The map reflects the real ideas in your video, PDF, or text, and how they actually relate.
Interactive on the page
Drag, zoom, and fold branches on a real map, or switch to an indented outline of the same tree.
Take it anywhere
Download it as PNG or SVG, as a Markdown outline, or as OPML to open in MindNode, XMind, and other mind-map apps.
Who it's for
Students
See how a topic hangs together before the exam, instead of memorizing a flat list of facts.
Researchers
Map how a talk or paper connects to ideas you already know, so the literature stops feeling flat.
Teachers
Sketch the structure of a unit from the reading, then use it to plan how you'll teach it.
