- Mind maps stay editable and explorable after they are generated.

Works in your browser
Open DeckOwl in Chrome, Edge, or Firefox on Windows. There is nothing to install and nothing to update.
Builds from your own material
Upload lecture slides, textbook PDFs, or notes. The mind map is built from what you gave it, not from a generic template.
Explore and edit
Expand or collapse branches, reorganize topics, and tighten the map until it matches how you think about the material.
How it works
Upload your material
Drop in a PDF, Word file, PowerPoint, plain text, or a photo of a page.
Generate the map
DeckOwl turns the content into a mind map with a central topic and labeled branches.
Study and adjust
Explore the branches, edit anything that is off, and quiz yourself on the same material.
A good study map starts with one central idea and splits it into a small number of branches, each holding one concept you can test yourself on. Generating the first draft from your own lecture notes saves time, and you can then move, rename, or delete branches to fit your course.

Frequently asked questions
Is there a free mind map software download for Windows?
DeckOwl does not require a download because it runs in your browser on Windows. The free plan includes 3 generations per month, and you can start without a credit card.
How many branches should a study mind map have?
Four to seven main branches is usually readable enough to scan in one pass. Each branch should hold one idea you could explain or test on its own.
How do I structure a mind map for a biology unit?
Put the topic, such as cell structure, in the center, then add one branch per organelle or process. Under each branch, add two to four facts you need to recall, like function or location.
Can I export my mind maps?
Exporting to PDF, DOCX, Anki, and CSV is part of paid plans. Plus costs $99.90/year or $9.99/month, and the free plan is for studying in the browser.
