A mind map maker that turns your PDFs and notes into a map
Upload a PDF, DOCX, PPTX, plain notes, or photos of pages. DeckOwl reads the text and lays out an editable mind map you can click through branch by branch.
Why a map built from your own material works better
Many people searching for a mind map maker already have a lecture or chapter they need to organize, and a blank canvas only helps if you know the structure already. Generating the map from your own file means the central topic and branches reflect what your course actually covers.
- Paste or upload notes and get a first-draft map in one step.
- Edit branch names, order, and sub-points after the AI builds the structure.
- Explore one branch at a time instead of scanning a crowded diagram.
- Turn the same material into flashcards or quizzes when you are ready to practice recall.
Starts from your own material
Drop in lecture slides, textbook chapters, or handwritten notes photographed on your phone. The map reflects what you actually need to learn.
Editable after generation
Rename branches, move subtopics, or delete what you do not need. The AI gives you a draft, and you keep control of the final structure.
Explore instead of scroll
Expand and collapse branches to focus on one area at a time, so a long document stays readable on the page.
How it works
Upload your material
Add a PDF, DOCX, PPTX, text file, or image of a page. Scanned pages are read with text recognition.
Let the AI draft the map
DeckOwl identifies the central topic and groups the main ideas into branches with sub-points beneath them.
Edit and explore
Adjust the layout to match how you think about the topic, then move through the branches to review and quiz yourself.
A useful map keeps branches short and lets you see how ideas connect. You can edit the draft to merge overlapping branches, add links you noticed yourself, or cut sections your instructor skipped.
Once the map is set, the same notes can become flashcards or quiz questions, so the map becomes a starting point for review rather than a finished poster.

Frequently asked questions
How do I choose the central topic for a mind map?
Pick the question or main concept the whole document is about, and write it as a short phrase in the center. If you cannot name it in a few words, the source may cover several topics that should be mapped separately.
How many main branches should a mind map have?
Most useful maps have four to seven main branches, which is about what a person can hold in mind at once. If you have more, group related branches under a shared parent to keep the map readable.
Can I edit the mind map after the AI creates it?
Yes. You can rename branches, move sub-points, and remove anything that does not fit your material. The generated map is a draft you shape to match your course.
Do I need a paid plan to export my study material?
Study in the browser is available on the free plan, which includes 3 generations per month. PDF, DOCX, Anki, and CSV export are part of the Plus plan at $39 per year or $7.99 per month, and students get 40% off with a school email.
