Turn your notes into an editable concept map with AI
Upload a PDF, DOCX, slide deck, text file, or photo of a page. DeckOwl builds a mind map of the main ideas and how they connect, which you can edit and explore.
Why start with a concept map maker instead of a blank page
A concept map maker earns its keep when it starts from your own material rather than an empty canvas. Upload a PDF, DOCX, slide deck, or notes and DeckOwl pulls out the key terms and how they connect, so you have a map to edit and explore right away.
- Pulls the central topic and main branches out of long readings
- Shows how sub-points relate to each parent idea
- Lets you rearrange and expand the map as your understanding grows
- Works from PDFs, DOCX, PPTX, plain notes, and photographed pages
Starts from your material
Your PDFs, DOCX files, PPTX slides, plain notes, and page photos become the source, so the map reflects your course rather than generic content.
Editable and explorable
Expand branches, reorganize ideas, and follow links between concepts to see how one idea depends on another.
Study from the map
Turn the same material into flashcards with spaced repetition or quizzes with explanations when you want to test recall.
How it works
Upload your source
Add a PDF, DOCX, PPTX, text file, or a clear photo of printed pages. Photos are read with text recognition.
Generate the map
DeckOwl identifies the central topic, the main branches, and the supporting points under each one.
Edit and review
Adjust the layout and wording, then work through the map branch by branch until the connections make sense.
Once the map exists, you can reshape it. Move branches, rename nodes, and add links you think are missing, since the map is a starting point for your own understanding rather than a final answer.

Frequently asked questions
How do I build a concept map that shows how ideas relate?
Start with one central question or topic, then list the main ideas that answer it. For each idea, add the supporting facts and label each link with the relationship, such as causes, requires, or is an example of.
How many branches should one concept map have?
Most useful maps have about three to seven main branches, each with a few sub-points. If a branch grows much larger, split it into its own map so the connections stay readable.
Can I export my concept map?
Exporting is a paid feature. The free plan lets you study in the browser, and Plus adds PDF and DOCX export along with unlimited generations.
Can DeckOwl read photos of my notes?
Yes, photos of pages are read with text recognition. Clear, well-lit photos of printed pages give the best results.
