Study with a mind map built from your own notes and PDFs
Upload a lecture PDF, a DOCX file or a photo of your notes and get a branching map of the main ideas, ready to edit and explore.
Why a mind map helps you study
Most students take notes in a straight line, but a mind map study tool shows how ideas connect, so you can see which concepts support which. Seeing the structure of a topic makes it easier to recall it in an exam.
- Shows how main ideas relate to supporting details
- Easy to edit when your lecture notes change
- Useful for subjects with many linked terms, such as geometry
- Pairs with flashcards and quizzes from the same material

Frequently asked questions
How do I make a mind map for the Pythagorean theorem?
Start with the main branch for right triangles, then add branches for the formula, the hypotenuse and how to solve for a missing side. Keep each sub-point short so you can recall it without the notes.
How does a mind map help with learning geometry?
It shows how definitions, formulas and examples link together, which makes it easier to see when a rule applies. Reviewing the map from the center outward is a good way to test recall.
Is there a free plan?
Yes, the free plan includes three generations per month and studying in the browser. Exports are included in the paid Plus and Pro plans.
Can I edit the mind map after it is generated?
Yes, you can rename branches, move ideas and expand or collapse sections. Students also get 40% off with a school email.
