Generate the full set

Starts from your material

Drop in a PDF, DOCX, PPTX, plain text, or a photo of a page and the map is built from what you actually need to learn.

Editable and explorable

Expand or collapse branches, reword nodes, and move through the map at your own pace instead of getting a static picture.

Study tools from the same source

Turn the same material into flashcards with spaced repetition or quizzes with explanations when the map is not enough.

How it works

Upload your notes

Add a file or paste text. No credit card is needed to start.

Generate the mind map

DeckOwl organizes the main ideas into branches and sub-points you can edit.

Explore and revise

Open branches to check understanding, then fix anything that looks off.

The free plan gives you 3 generations per month and lets you study in the browser. Exports to PDF, DOCX, Anki, and CSV are part of Plus, which costs $39/year or $7.99/month and removes the generation limit.

Students get 40% off with a school email, so the paid tier is an option if you need more maps during a heavy term.

Frequently asked questions

How do I organize a mind map for studying?

Put the central topic in the middle, then add a few main branches for the big categories in your material. Keep each sub-point short so you can recall it without rereading the source.

How many branches should a study mind map have?

Most useful maps have a small number of main branches, with only a few sub-points under each. If a branch gets crowded, split it into two related branches.

Can I export my mind map?

Exports are a paid feature. Plus includes PDF, DOCX, Anki, and CSV export along with unlimited generations.

Is there a free plan?

Yes. The free plan includes 3 generations per month and lets you study in the browser, but it does not include exports.
