  2. 2

    AI builds the map

Choosing Free Online Mind Mapping Tools

Free online mind mapping tools let you draw ideas as a branching diagram in your browser, with no installation. A central topic sits in the middle, and related ideas spread out as branches. Most people use them to plan essays, organize projects, or review lecture notes before an exam.

  • Central topic: the single idea every branch connects back to
  • Main branches: the major categories or themes under the topic
  • Sub-branches: supporting details, examples and definitions
  • Export and sharing: saving maps as images or links for others

Once you have a map, use it to revise by covering branches and recalling them from memory. CogniGuide can build a personalized map from your own notes, so your study material is ready in minutes.
