Turn any PDF into a free concept map you can edit
Skip the generic printable. DeckOwl builds a mind map from your own lecture slides, textbook chapter, or notes, so the branches match what your course actually teaches.
Why a custom concept map beats a generic printable
A printable template shows someone else's structure, not the links in your own lecture. A free concept map PDF built from your notes puts your course's terms and relationships on the page.
- Maps come from your own source material, not a generic template.
- Every node and link can be edited after the map is generated.
- Free plan: study in the browser with 3 generations per month.
- PDF export is included with Plus at $39/year or $7.99/month.
Built from your material
Upload a PDF, DOCX, PPTX, text file, or photo of a page, and the map uses the terms and links in your own source.
Editable and explorable
Rename branches, move nodes, and expand or collapse sections so the map fits how you think about the topic.
Study from the same map
Turn map topics into quizzes or flashcards with spaced repetition when you want to test what you remember.
How it works
Upload your notes or PDF
Add a file or paste text. Photos of pages are read with text recognition.
Review the generated map
Explore the central idea and its branches, then edit any label or link that needs correcting.
Study or export
Explore and study in the browser on the free plan. PDF export is part of Plus.
The free plan lets you create and explore maps in the browser with 3 generations per month. Downloading a PDF is part of Plus, which also offers unlimited generations and Anki and CSV export.
Good maps are short and specific. Start with one central idea, then branch into the subtopics your instructor emphasized, and keep each link labeled with a short phrase.

Frequently asked questions
How do I make a concept map for chemical bonding?

How many branches should a chemistry concept map have?
