    Upload your notes, slides or PDF, or type the topic you want to study.

  2. 2

    AI builds the map

    CogniGuide organizes the content into a central topic with expandable branches.

  3. 3

    Study, expand and quiz

    Explore the branches, add detail with AI, then test yourself with a quiz.

Choosing the Best Topic for a Mind Map

The best topic for a mind map has clear parts that relate to one central idea. Subjects such as the human body, the water cycle, the causes of World War I or the plot of a novel split naturally into branches. Each branch holds a group of related facts, so the map shows how the pieces connect.

  • Clear parts: subjects with distinct components, stages or causes
  • Connected ideas: topics where branches relate to one central idea
  • Defined scope: a single chapter or unit works better than a whole course
  • Examples and terms: subjects with vocabulary and case studies to add as children

Once you have a topic, a map helps you spot gaps and review quickly. Add your own notes and CogniGuide will generate a personalized mind map you can expand and quiz yourself on.
