About Online Mind Mapping

An online mind map is a diagram you build and edit in a web browser. It starts with one central topic, then splits into main branches and smaller sub-ideas. Because it runs in the browser, you can open it on any device, share it with classmates, and update it as your notes change. Online maps suit students, teachers and professionals who need to organize large amounts of information quickly.

  • Central topic: the single idea the whole map is built around
  • Main branches: the major themes or sections of the material
  • Sub-branches: supporting details, examples and definitions
  • Links and notes: connections between ideas and key facts

Use the map to review before an exam, plan a project or outline an essay. CogniGuide can build a personalized online mind map from your own notes or PDF in a few minutes.
