Turn your PDF or notes into a free mind map, no download needed
No install. Upload a PDF, DOCX, PPTX, plain notes, or a photo of a page and get an editable mind map you can explore in your browser.
Free mind maps without installing anything
Most students who want a free mind map are trying to turn a dense chapter into something they can see all at once. A desktop download takes time to install and learn, and it still leaves you to type out every branch yourself.
- No software to install or update before you start studying
- Starts from your PDFs, slides, or notes rather than a blank canvas
- Editable branches so the map matches your course outline
- Free plan with no credit card required to try it
Built from your material
Upload your own lecture slides, textbook chapter, or handwritten notes photographed on your phone, and the map is drawn from that content.
Editable and explorable
Rename branches, move nodes, and expand or collapse sections so the map fits how you think about the topic.
Turn branches into study tools
Use the same material to generate flashcards with spaced repetition or quiz questions with explanations.
How it works
Upload your source
Add a PDF, DOCX, PPTX, text file, or image of a page. Images are read with text recognition.
Generate the mind map
DeckOwl organizes the main ideas into a central topic with branches and sub-points you can review.
Edit and study in the browser
Adjust the map, then explore it branch by branch. Exports to PDF or DOCX are part of the paid Plus plan.
DeckOwl builds the first draft from your own material, so the structure reflects what your instructor actually covered. You can then reshape the map in the browser, which is useful when you want to group related concepts before an exam.
The free plan includes 3 generations per month and lets you study in the browser. If you need to export your map or want unlimited generations, the Plus plan covers that.

Frequently asked questions
Is there a free download for DeckOwl?
DeckOwl runs in your browser, so there is nothing to install. The free plan includes 3 generations per month and lets you study in the browser.
How do I make a mind map from lecture notes?
Start with a single central topic, such as the chapter title, and add the major themes as first-level branches. Then add the supporting facts, definitions, and examples under each theme.
How many branches should a study mind map have?
Most useful maps have 4 to 7 main branches, each with 2 to 4 sub-points. If a branch grows much bigger, split it into its own map so each one stays readable.
Can I export my mind map?
Exporting is a paid feature. The Plus plan includes PDF and DOCX export, and the Pro plan adds stronger AI models and bulk upload.
