A mind map maker that turns your PDFs and notes into a map
Upload PDFs, Word files, slides, or photos of pages. DeckOwl builds an editable mind map with branches you can explore and change.
How a mind map maker helps you study
A mind map maker is most useful when it starts from your own material rather than a blank page. Upload lecture slides, a textbook chapter PDF, or photos of handwritten notes, and DeckOwl reads the text and groups the main ideas under branches you can follow.
- Start with the chapter or lecture you are studying this week.
- Check branch labels against your source before relying on them.
- Redraw the map from memory, then compare it to the original.
- Turn weak branches into flashcards or quiz questions.
Editable branches
Change any branch or reorganize the map after it is generated, so it matches how your course is structured.
Built from your files
Works with PDF, DOCX, PPTX, plain text notes, and photos of pages read with text recognition.
Study from the same map
Turn the same material into flashcards or quiz questions when you want to test recall.
How it works
Upload your material
Add a PDF, DOCX, PPTX, set of notes, or a photo of a page.
Generate the map
DeckOwl organizes the main topics into branches with their sub-points.
Explore and edit
Open branches, adjust the structure, and study from the map as you go.
Mind maps work best when you can change them. Every branch in the generated map is editable, so you can merge topics, drop what you do not need, and add your own connections as the course moves on. The free plan lets you study in the browser, and exports are part of the paid plans.

Frequently asked questions
How many branches should a mind map for one chapter have?
Most chapter maps work well with five to seven main branches, each with two to four sub-points. A map with too many branches becomes hard to recall from.
How do I study a cell biology mind map effectively?
Cover the map and name each branch from memory, then check which sub-points you missed. Repeat the exercise the next day to strengthen recall.
Can I export my mind map?
Exports are included in the paid plans, while the free plan covers studying in the browser without exports.
Do I need a credit card to start?
No. You can start on the free plan, which includes three generations per month, without adding a credit card.
