Making a Free Mind Map Online
A mind map is a diagram that starts with one central idea and grows outward through branches for related themes, facts and examples. To make a mind map online for free, put the main topic in the centre, then add the major subtopics as first-level branches. Each branch then gets smaller points, so the structure shows how ideas connect.
- Central idea: the single topic the whole map is about
- Main branches: the major themes or categories under the topic
- Sub-branches: supporting details, examples and dates
- Connections: links that show how branches relate to each other
Use the finished map to review before a test, plan an essay, or check your understanding. CogniGuide can build a personalized mind map from your own notes or PDF, so you can start studying right away.
