How a concept map diagram maker works

Drawing concept map diagrams by hand takes time you would rather spend understanding the material. DeckOwl reads your lecture slides, notes or textbook chapter and lays out the main ideas as linked branches you can edit.

  • Start with one central topic so the map has a clear root.
  • Keep each branch to one idea, with short labels.
  • Label links with a verb phrase such as causes or requires.
  • Redraw the map from memory to test what you actually remember.

Mind map from any source

Upload a PDF, DOCX, PPTX, plain text or a photo of a page and the main ideas become connected branches.

Editable and explorable

Rename nodes, add branches and expand or collapse sections as you study the diagram.

Study beyond the map

Pair the diagram with flashcards and quizzes generated from the same material.

How it works

Upload your material

Add a PDF, DOCX, PPTX, notes or a photo of a page.

Generate the map

DeckOwl identifies the central topic and arranges the supporting ideas as branches.

Edit and explore

Adjust labels and structure, then study the diagram in your browser.

Good diagrams link each term to the details that support it. Start from the central topic, check that the top-level branches cover the big ideas, and remove anything that does not connect back to the topic.

Frequently asked questions

How do I know if a concept map diagram is complete?

Check that every major term from your source has a branch and that each link is labeled with a relationship. Then cover the map and rebuild it from memory to find gaps.

What makes a good link label in a concept map?

Use a short verb phrase such as causes, requires or produces so the link states how two ideas relate. Vague labels like related to rarely help you recall anything.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser, but exports are part of the paid plans.

Can I export my maps?

Exporting is a paid feature. Plus includes PDF, DOCX, Anki and CSV export, and students get 40% off with a school email.
