Generate a NoteGPT-style mind map from your PDFs and notes
Upload a PDF, DOCX, PPTX, plain text file, or a photo of a page. DeckOwl builds an editable mind map you can explore branch by branch.
How a mind map helps you study a dense topic
Students working through lecture slides or a long textbook chapter often need the structure of a topic, not another wall of text. A NoteGPT-style mind map generator pulls the main ideas out of your own material and arranges them as a central topic with linked branches.
- Works with PDF, DOCX, PPTX, plain text, and photos of pages
- Lets you edit and rearrange every branch after generation
- Keeps maps explorable so you can focus on one topic at a time
- Pairs with flashcards and quizzes built from the same notes
Editable maps
Rename, move, and expand branches after generation so the map matches your course notes instead of a generic outline.
Explorable branches
Open one main topic at a time, check its sub-points, and collapse the rest to keep focus on what you are studying.
Study tools from the same source
Turn the same material into flashcards with spaced repetition or into quizzes with explanations when you are ready to test recall.
How it works
Upload your material
Add a PDF, DOCX, PPTX, plain text notes, or a photo of a page. Images are read with text recognition.
Review the generated map
Scan the central topic and main branches to confirm the structure matches what your teacher covered.
Edit and explore
Adjust branches, add missing ideas, and walk through the map until you can rebuild it from memory.
Because the map is generated from your files, the branches reflect what your course actually covers. You can edit them, reorder them, and expand the parts that need more detail. Free accounts can explore and study maps in the browser, while paid plans add exports.
Use the map as a recall exercise: cover the sub-points, say each one aloud, then check yourself. Repeating this a day later shows which connections you have kept and which need another pass.

Frequently asked questions
How do I study a mind map effectively for a cell biology exam?
Cover the sub-points and try to recall each one from its main branch before checking. Redrawing the map from memory a day later shows which connections have stuck.
Should I start with the whole chapter or one branch at a time?
Start with one main branch, such as mitosis, and learn its sub-stages before moving on. Then return to the central topic to see how the branches connect.
Can I edit the mind map after it is generated?
Yes. You can rename, rearrange, and expand branches so the map matches your course notes.
Can I export my mind map?
Exports are part of the paid Plus plan, which costs $39/year or $7.99/month. The free plan lets you explore and study maps in the browser.
