A mind map maker that starts from the notes you already have
Upload a PDF, DOCX, PPTX, plain text file, or a photo of a page. DeckOwl reads the material and drafts a mind map you can rearrange, expand, and explore branch by branch.
Why a generated map beats starting from an empty board
Staring at an empty whiteboard wastes the first half hour of studying. A mind map maker that reads your own lecture notes gives you a structured first draft, so your time goes into understanding the connections instead of placing boxes.
- Works from PDFs, Word and PowerPoint files, plain text, and photos of pages
- Every node is editable, so the map stays accurate to your course
- Explore branches one level at a time instead of scanning a crowded diagram
- Pairs with flashcards and quizzes made from the same source material
Built from your material
Start with lecture slides, textbook chapters, or handwritten notes photographed on your phone. The map uses the actual headings and terms from your files.
Editable branches
Rename, move, merge, or delete any node. The AI draft is a starting point, so the final map reflects how you understand the topic.
Explore at your own pace
Open a branch to see its sub-points and expand only the parts you need. It works in the browser on the free plan.
How it works
Upload your notes
Add a PDF, DOCX, PPTX, text file, or image of a page. No account setup is needed to try it.
Review the draft map
DeckOwl proposes a central topic with main branches and sub-points. Check that the structure matches your course.
Edit and study
Adjust the layout, then explore the map or turn the same material into flashcards and quizzes.
The draft is built from what your instructor actually covered. Headings become main branches, key terms become sub-points, and you can reshape everything once you spot a missing idea or a misplaced term.
Because the map is editable and explorable, it also works as a review tool. Collapse what you already know, open what you do not, and return to the same map before an exam.

Frequently asked questions
How do I organize a mind map from lecture notes?
Put the course topic in the center, then make each main heading from your notes a first-level branch. Add the key terms and examples under those headings as shorter sub-branches.
How many branches should a study mind map have?
Most topics work well with four to seven main branches. If a branch needs more than about five sub-points, split it into its own sub-map so each part stays easy to scan.
Can I edit the mind map after it is generated?
Yes. You can rename, move, merge, or delete any node, so the final map can match your course rather than the first draft.
Do I have to pay to export my study material?
The free plan lets you study in the browser with 3 generations a month, but exports are paid features. The Plus plan includes PDF, DOCX, Anki, and CSV export with unlimited generations.
