Generate the full set

Built from your own material

Start with lecture slides, textbook chapters, or handwritten notes photographed with your phone. Text recognition reads the page before the map is built.

Explore and edit the map

Expand branches, rearrange topics, and fix anything the AI got wrong. The map stays editable so it matches how your course is organized.

Turn the map into practice

Use the same material to generate flashcards with spaced repetition and quizzes with explanations, so the map is not the only study step.

Frequently asked questions

How do I study from a mind map?

Cover the sub-points and try to recall each branch from its main topic, then check yourself against the map. Repeat the drill for each branch until you can rebuild the whole structure from memory.

How many main branches should a biology chapter mind map have?

Most chapters work well with 4 to 7 main branches, each covering one major concept such as structure, function, or process. Split a branch into its own map if it holds more than about four sub-points.
