Free Online Mind Map Basics
A mind map is a diagram that places one central idea in the middle and connects related ideas as branches. Each branch can split into smaller subtopics, so the whole structure reads from general to specific. To make one online for free, you can start with a central topic, add the main categories, then fill each branch with key terms, examples and facts.
- Central topic: the single idea the whole map is built around.
- Main branches: the major categories that split the subject.
- Subtopics: smaller ideas that support each main branch.
- Key details: facts, dates, terms or examples on the lowest level.
Use the finished map to review before an exam, plan a project or explain a subject to someone else. CogniGuide can build a personalized mind map from your own notes, so the structure matches exactly what you need to learn.
