Turn your notes into a mind map you can explore
DeckOwl builds an editable AI mind map from your PDFs, slides, or notes. The free plan runs in your browser, so there is nothing to download first.
Why a browser-based map can replace a download
Many students searching for a free mind map app want a visual summary of a lecture or chapter they can use today, not another program to install and update. DeckOwl creates that map from your own material, so the branches reflect your course rather than a generic template.
- Works in your browser with nothing to install on the free plan
- Builds maps from PDFs, slides, notes, and photos of pages
- Lets you edit branches so the map matches your course
- Pairs with flashcards and quizzes for active recall
Editable branches
Rename, move, or delete any node so the map matches how your course is organized.
Explorable structure
Follow each main idea outward to its supporting details instead of scrolling a long summary.
Starts from your material
Upload a PDF, DOCX, PPTX, plain text, or a photo of a page and build the map from that.
How it works
Add your material
Upload a file or paste your notes. Photos of pages are read with text recognition.
Generate the map
DeckOwl pulls out the main topics and arranges them into a mind map.
Explore and edit
Open branches, adjust the layout, and keep the parts you need for review.
The free plan includes 3 generations per month and studying in the browser. Paid plans add unlimited generations and PDF, DOCX, Anki, and CSV export, so you can take your work out of the app when you need it.
A map is most useful when you test yourself on it. Hide a branch, explain its sub-points from memory, then open it to check. Pair the map with flashcards or a quiz for the topics that still feel shaky.

No. The free plan runs in your browser, so you can upload material and study the map without installing software.

Cover the sub-points of one main branch and explain them from memory, then check the map. Repeat with the branches you missed.
How many main branches should a mind map have?
Keep it to the core ideas of one lesson, often five to eight, so each branch stays readable and easy to recall.
