Generate the mind map

DeckOwl drafts a branched map from your content in one pass.

Edit and explore

Reshape the branches and study in the browser. Exporting is a paid feature.

A map is only useful if it reflects what you still need to learn. Once the first draft is generated, move weak branches, merge overlapping ideas, and expand the sections you find confusing, then turn the map into a quiz or flashcards when you are ready to test recall.

Frequently asked questions

How do I organize cell biology notes into a mind map?

Start with the broad topic, such as cell structure, and make each major organelle or process a main branch. Add function, location, and key facts as sub-branches so you can quiz yourself on each one.

What makes a good main branch in a study mind map?

A main branch should be a single concept you could explain in a few sentences on its own. If a branch needs a long paragraph to define, split it into two smaller branches.

Can I export my mind map on the free plan?

No, the free plan lets you study in the browser but does not include exports. Plus at $99.90/year or $9.99/month adds PDF and DOCX export, and Pro at $14.99/month adds additional export formats.

How many free generations do I get?

The free plan includes 3 generations per month, and you can start without a credit card. Students can get 40% off a paid plan with a school email.
