Free Mind Mapping Online: How It Works

A mind map is a diagram that places one central idea in the middle and branches out to related subtopics. A free online mind map tool lets you create this structure in your browser, without downloading software. You start with a topic or a file, and the map shows how the main ideas connect.

Central topic: the main idea placed at the center
Main branches: the major categories that support it
Sub-branches: details, examples and evidence under each branch
Connections: links that show how ideas relate across branches

Use the map to review before a test, plan a project or outline an essay. CogniGuide can build a personalized mind map from your own notes, so you can start from your material instead of a blank page.
