How to Make a Mind Map Online

Three steps from raw notes or a topic to a finished, editable map.

  1. 1

    Add your material

    Upload a file or image, or type the topic you want to map out.

  2. 2

    AI builds the map

    The generator sorts your content into a central idea with main and sub branches.

  3. 3

    Study, expand or quiz

    Expand weak branches, edit the wording, then export or turn the map into a quiz.

Using an Online Mind Map Maker Well

A mind map places one central idea in the middle and draws branches outward for related concepts, causes, examples and details. An online mind map maker does the layout for you, so you can focus on the ideas. Good maps keep each branch short, use keywords instead of sentences, and group related points together. Start with the main theme, then add the major categories before filling in details.

  • Central idea: the single topic the whole map is organized around
  • Main branches: the broad categories that split the topic
  • Sub-branches: supporting facts, examples and definitions
  • Connections: links between branches that show cause or relation

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 in the same way.
