What CogniGuide Does on the Free Plan

A free plan with a weekly allowance, built around turning your own study material into a map.

Build maps from your files

How a Free Online Mind Map Gets Made

Three steps from raw notes to a map you can study, share or export.

  1. 1

    Add your material or a topic

    Upload a file or type a topic into the generator to start a new map.

  2. 2

    AI builds the branches

    The tool organizes your content into a central idea with expandable main branches.

  3. 3

    Study, expand and export

    Edit the map, add detail with AI, then quiz yourself or export it as PNG or PDF.

Choosing a Free Online Mind Mapping Tool

Free online mind mapping tools let you sketch ideas as a branching diagram in a browser, with no install. Most offer a basic free tier, but limits differ on the number of maps, file import, AI features and export formats. A useful tool should start from your existing notes, not only from a blank canvas, and let you refine the structure afterward.

  • File import: whether PDFs, slides or documents become a map automatically
  • AI expansion: adding detail to a branch without retyping everything
  • Editing control: changing node text and reorganizing branches freely
  • Export options: getting a PNG or PDF for notes, slides or printing
  • Sharing: sending a link so classmates or teachers can view the map

Use the map to review a subject, spot gaps and plan an essay. CogniGuide can turn your own notes into a personalized map on its free plan, so you can start studying from your material right away.
