What an Automatic Mind Map Shows

An automatic mind map is a diagram that a tool builds for you from a body of text or a topic. The central idea sits in the middle, and the main themes branch outward. Each branch then splits into subtopics and supporting details. Because the structure comes from the content itself, the map shows how ideas relate, not just a list of facts.

Central topic: the core idea everything else connects to
Main branches: the major themes or sections of the material
Subtopics: smaller ideas that explain each main branch
Details and examples: facts, dates or terms that support each subtopic

Use the map to review before an exam, check that you understand how the parts connect, or plan an essay. Create your own automatic mind map from your notes with CogniGuide.
