    Upload a file or type a topic into the box to start your map.

  2. 2

    AI Builds the Map

    The AI organizes the content into a central idea with labeled branches.

    Study, Edit and Export

    Expand nodes, edit text, quiz yourself, then export as PNG or PDF or share a link.

Choosing an Online Mind Mapping Tool

An online tool for mind mapping lets you organize ideas in a web browser without installing software. A mind map starts with one central topic and branches out into related subtopics, keywords and examples. Online tools make this faster by arranging the layout for you and letting you add, move or expand nodes as your understanding grows.

  • Central topic: the main subject placed in the middle of the map
  • Main branches: the major themes that split the subject
  • Subtopics: details, causes and examples under each branch
  • Links and notes: connections between ideas and supporting facts

Use the finished map to review before exams, plan essays or check your understanding. CogniGuide can build a personalized map from your own notes, so you can start from your material instead of a blank page.
