Turn your own notes into a revision mind map

A revision mind map shows how a topic fits together, with the central idea in the middle and related points branching outward. DeckOwl builds one from your PDFs or notes, and you can edit and explore it.

What a revision mind map is and why it helps

Picture one topic in the middle of a page with its main themes radiating out like branches, and smaller details hanging off each branch. That layout is a revision mind map, and it works because you remember relationships between ideas more easily than a list of facts.

Put the topic name in the center and keep branch labels to a few words.
Give each main branch two to four sub-points so you can recall them in groups.
Redraw or reopen the map a day later to check what you remember without looking.
Link branches that depend on each other, since the connections are what you will be tested on.

How it works

Upload your notes

Add a PDF, slides, a document, or photos of your handwritten pages. Text is read from images automatically.

Generate the map

DeckOwl sorts your material into a central topic and main branches with sub-points beneath each one.

Edit and revise

Adjust any branch you want, then walk through the map from the center outward to test your recall.

Most students make these by hand from a textbook chapter, which takes time and often means copying text without deciding what matters. An AI version starts from your own notes, so the branches reflect your course, not a generic outline.

A good map is short enough to fit on one screen. Each branch should hold a single idea, and the sub-points should be details you could explain out loud without looking.

Frequently asked questions

How many main branches should a revision mind map have?

Most useful maps have between four and seven main branches, one for each major theme in the chapter. If you need more, split the topic into two maps rather than crowding one page.

How do I use a mind map for revision instead of rereading notes?

Cover the map, then try to rebuild each branch from memory, and check the gaps against your notes. Repeating this a few times is more effective than reading the same notes again.

Can I edit a mind map after DeckOwl creates it?

Yes, you can rename, move, and add branches to any map. Exporting a map to PDF is available on the Plus plan, which is $39/year or $7.99/month.
