Brainstorm Map Method and Structure
A brainstorm map is a visual way to generate and organize ideas. Put the central question in the middle, then draw main branches for the broad themes that come to mind. Add short sub-ideas to each branch, and keep writing words, not sentences. Quantity comes first, sorting comes second.
- Central idea: the question or goal, written in the middle
- Main branches: broad themes that answer the central idea
- Sub-ideas: specific points, examples or options under each branch
- Gaps: branches with few entries show where to think further
- Priorities: the strongest branches become your plan or essay outline
Once the map is drafted, use it to choose ideas, plan a project or revise for a test. CogniGuide can build a personalized brainstorm map from your own notes, so you can start from what you already have.

Brainstorm Map Questions
Common questions about making a brainstorm map and using one with CogniGuide.
What should go in the center of a brainstorm map?
Put one clear question, goal or topic in the center. A specific prompt like How can we reduce commute time? works better than a broad word like Transport, because every branch can then answer it directly.
How many branches should a brainstorm map have?
Most maps work well with four to six main branches. Each branch should hold two to five sub-ideas. Too few branches usually means the thinking is shallow; too many make the map hard to scan.
Which files can CogniGuide turn into a brainstorm map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images. You can also type a topic directly without uploading anything.
Can I turn my brainstorm map into a quiz?
Yes. A CogniGuide map can be turned into a quiz to test yourself on the ideas, and the same notes can also become flashcards. The free plan includes 5 creations a week.
