Choosing the Best Online Mind Mapping Tool

A mind map is a diagram that places one central idea at the center and branches out to related subtopics. The best online mind mapping tools make this quick, keep maps easy to edit and let you export or share them. Good tools also reduce manual work by building the first draft for you from documents or notes, so you can spend more time reviewing the ideas than arranging boxes.

  • Central topic: the single idea the whole map is organized around
  • Main branches: the major themes that split from the center
  • Sub-branches: supporting details, examples and definitions
  • Export and sharing: PNG or PDF files and links for others to view

Use a finished map to review before an exam, plan a project or explain a subject to someone else. CogniGuide can build a personalized map from your own notes in minutes.
