Turn any PDF into a mind map for free
Upload a textbook chapter, lecture slides, or your own notes. DeckOwl builds a mind map you can edit, reorganize, and explore branch by branch.
Why a mind map helps with dense PDFs
A forty-page chapter is hard to scan, and a mind map shows how its ideas connect at a glance. If you want to convert a PDF into a mind map free, DeckOwl reads the file and builds branches from its headings and key terms.
- Upload a PDF, DOCX, PPTX, or photo of a page and get a mind map from its content.
- Edit branches so the map reflects your course, not just the file's layout.
- Use the free plan to build and explore maps, with 3 generations per month.
- Upgrade to Plus for exports and unlimited generations when you need a copy to share or import.
Reads your file
Works with PDF, DOCX, PPTX, plain text, and photos of pages read with text recognition.
Editable branches
Rename, reorganize, or delete branches so the map matches how your course frames the material.
Explore before you study
Open each branch to see its sub-points, then use the same material for flashcards or quizzes.
How it works
Upload your PDF or notes
Add the file or paste your text. No credit card is needed to start.
Review the mind map
Check the main branches and sub-points, and edit anything that is missing or off.
Study in the browser
Explore the map on the free plan. PDF and other exports are part of Plus.
Each map is editable, so you can rename branches, reorganize them, or remove anything you do not need before you study. The free plan includes 3 generations per month and studying in the browser, but not exports.
If you need a PDF or Anki-ready copy of the map, export is part of the Plus plan at $39/year or $7.99/month. Students get 40% off with a school email.
