Making a free mind map from your own notes
Students who need a free mind map usually have a chapter of lecture slides, a stack of notes, or a textbook section they want to see as connected ideas rather than a long list. DeckOwl reads PDF, DOCX, PPTX, plain text, and photos of pages, then drafts a map with the main topic at the center and related ideas branching outward. You can edit the nodes and follow each branch to see how the ideas connect.
- Start with the main topic at the center so the map has a clear anchor.
- Keep each branch to one idea, and put supporting details on sub-branches.
- Use the map to spot gaps, such as a branch with no sub-points, before a test.
- Compare the map with your source material to confirm nothing important was left out.
Built from your own material
Drop in lecture slides, a textbook chapter, or handwritten notes photographed on your phone, and the map is drawn from that content.
Editable and explorable
Rename branches, rearrange nodes, and follow connections between ideas instead of reading a flat list of terms.
Free to start
The free plan includes 3 generations per month and browser study. No credit card is needed to begin.
How it works
Upload your notes
Add a PDF, DOCX, PPTX, text file, or image of a page.
Review the map

Study from the map
Explore the connections in your browser, then turn the same material into quizzes or flashcards if you need them.
The free plan includes 3 generations per month, and you can study the finished map in your browser. Exports to PDF, DOCX, Anki, and CSV are part of the paid Plus plan at $39/year or $7.99/month. Students with a school email get 40% off, and no credit card is needed to start.

Frequently asked questions
How do I organize the nervous system into a mind map?
Start with the central nervous system and peripheral nervous system as the first branches, then add structures and functions under each. Keep sub-branches to a few words so the map stays readable.
What belongs on the main branches of a nervous system mind map?
Main branches usually cover the central and peripheral nervous systems, with autonomic and somatic divisions under the peripheral side. Neurons and the action potential often sit on separate branches for cellular detail.
Is the free plan of DeckOwl enough to make a mind map?
The free plan includes 3 generations per month and browser study, which works for a few maps. Exporting is a paid feature on the Plus plan.

Exports are not included on the free plan. Plus, at $39/year or $7.99/month, adds unlimited generations and PDF, DOCX, Anki, and CSV export.
