Turn your notes and photos into a free mind map
DeckOwl turns PDFs, Word files, slides, notes, or photos of pages into an editable, explorable mind map you can study in your browser.
How a free mind map helps with visual topics
Anatomy, lab diagrams, and maps are easier to learn when each part sits under its main branch, and a free mind map lets you build that structure from your own material. DeckOwl reads PDFs, Word files, slides, notes, and photos of pages, then groups the text into branches you can expand and edit.
- Start from your own PDF, slides, or notes instead of a generic template
- Photos of printed pages are read with text recognition for label text
- Branches can be edited, so you can reorganize as you learn the material
- Map topics can then be turned into flashcards or quizzes for review
Built from your material
Upload a PDF, DOCX, PPTX, or plain text notes and get a map organized around the main ideas.
Photos of pages work too
Pictures of printed pages are read with text recognition, so labels and headings become map branches.
Explore at your own pace
Expand and collapse branches to focus on one part of a diagram-heavy topic at a time.
How it works
Add your source
Upload a file, paste notes, or snap a photo of a page or diagram's labels.
Generate the map
DeckOwl organizes the material into a main topic with branches and sub-points.
Edit and study
Adjust branches, then explore the map in the browser to review each part.
Mind maps in DeckOwl are text-based, so they work best when your diagram has clear labels and captions. The Free plan includes 3 generations per month and browser study. Exporting maps to PDF or DOCX is part of Plus, so that is where a printable copy fits.

Frequently asked questions
How do I study a diagram-heavy topic like the heart?
Turn the labeled diagram into a map with one main branch for the chambers and one for the valves and vessels. Then cover the sub-points and name each part from memory before checking your answer.
Does a mind map help more than a plain list for memorizing parts of a system?
Grouping related parts under one branch shows how they connect, which often makes them easier to recall than a flat list. Review the branches in a different order to test whether you can rebuild the structure.
Is the mind map generator free to use?
Yes, the Free plan includes 3 generations per month and studying in the browser. No credit card is needed to start.
Can I export my mind map?
The Free plan does not include exports. PDF and DOCX export come with Plus at $39/year or $7.99/month.
