Turn your PDF or notes into an editable mind map online

A good mind map puts one central idea in the middle, then places main branches around it with short sub-points under each. Building that structure by hand takes time, especially when the source is a long lecture deck or a chapter of dense text. Generating a first draft from your own material gives you a structure to check against the source instead of starting from a blank page.

Once the draft exists, the useful work is editing it. Remove branches that repeat each other, merge sub-points that say the same thing, and make sure every branch matches something you were actually taught. The map then becomes a study tool you can test yourself with, not just a picture of your notes.
