How a mind map converter structures information
A mind map converter reads a text and identifies its central idea, then sorts the rest into main branches and subtopics. Each branch holds one theme, so the structure shows how ideas relate instead of listing them in a line. This makes long readings easier to scan and revise.
- Central topic: the core subject placed at the center
- Main branches: the major themes drawn from headings and sections
- Subtopics: supporting points grouped under each theme
- Details: examples, dates or definitions at the outer level
Once the map is built, use it to revise, check gaps and explain the subject aloud. CogniGuide can create a personalized map from your own notes, so the structure matches what you actually studied.
