Make a concept map from your notes without a credit card
Upload a PDF, DOCX, PPTX, pasted notes, or a photo of a page. DeckOwl builds an editable mind map you can expand, rearrange, and review branch by branch.
How a concept map maker fits into studying
A concept map maker is most useful when you already have lecture slides or a textbook chapter and want the big ideas laid out before a test. DeckOwl builds the map from your own files, so the structure reflects what your instructor actually covered.
- Start with no credit card and try a map on your own notes.
- Edit node labels and branch order before you study from the map.
- Review the map one branch at a time instead of memorizing it all at once.
- Export maps to PDF on the Plus plan when you need a printed copy.

Frequently asked questions
How many branches should a concept map for biology have?
Most chapter-level maps work well with 5 to 8 main branches, each with 3 to 5 sub-points. Fewer branches usually means the topics are too broad to review quickly.
How do I study a concept map instead of just looking at it?
Cover the labels and try to name each branch from memory, then check yourself against the map. Redraw one branch from scratch each session to see where your recall breaks down.
Can I try DeckOwl without a credit card?
Yes, you can start without a credit card. The free plan includes 3 generations per month and studying in the browser, while exports require the Plus plan.
Is the free plan enough to map a class?
The free plan covers a few chapters at 3 generations per month. Plus removes the cap with unlimited generations and adds PDF and DOCX export.
