Why start from your own material

A free mind map builder is most useful when it starts from your own readings and notes rather than a generic template. Your lecture slides and textbook chapters already contain the structure your exam will test, so the map reflects what your class actually covers.

Works with your own files

Upload PDFs, Word documents, slide decks, plain text, or photos of pages. Photos are read with text recognition.

Editable and explorable

Your map is a starting point you can change. Expand branches, reorder ideas, and click through the structure as you study.

Free to start in the browser

The free plan includes 3 generations per month and studying in the browser. Exports to other formats are part of the paid plans.

How it works

Upload your material

Add a PDF, DOCX, PPTX, or pasted notes. You can also photograph a page and let text recognition read it.

Generate the map

DeckOwl organizes the content into a mind map with a central topic, main branches, and sub-points.

Explore and edit

Open branches, adjust anything that looks off, and study the map directly in your browser.

Mind maps work well for seeing how ideas connect, such as how a main concept splits into causes, examples, and exceptions. Because the map is editable, you can remove weak branches, add your own examples, and keep the version that matches your course.

If you want to save or share the map outside the browser, export options are included with the Plus plan at $99.90 per year or $9.99 per month. Students can get 40% off with a school email.

Frequently asked questions

How do I organize a mind map for US government branches?

Start with the three branches as main nodes: legislative, executive, and judicial. Then add each branch's key bodies and powers as sub-points, and link related ideas such as checks and balances across branches.

How many main branches should a mind map have?

Five to seven main branches is a practical range for most study topics, since more than that becomes hard to scan. Group smaller details under the branch they support rather than giving each its own top-level node.

What does the free plan include?

The free plan includes 3 generations per month and studying in the browser with no credit card needed to start. Exporting files is available on the Plus plan.
