Why a custom map beats a generic PDF

Instead of hunting for a printable class 9 science mind map PDF that covers a different syllabus, you can turn the chapter you are studying into one. Matter, motion, cells, and atoms each have their own vocabulary and relationships, and a map built from your notes keeps those links intact.

Works with PDF, DOCX, PPTX, plain text notes, and photos of textbook pages
Editable nodes so the map follows your teacher's order of topics
Explorable layout for reviewing one branch at a time
Free plan includes 3 generations per month with study in the browser

Edit and explore

Adjust the branches, then click through the map to study each section.

Start with the central topic from your chapter heading, then let the generator pull out the main branches such as definitions, laws, and examples. Because the map is editable, you can reshape it as your teacher covers more material.

Maps are easiest to use when each branch holds a short, testable idea rather than a full paragraph. Keep sub-points to a few words so you can recall them quickly.
