Editable, explorable maps

Expand, collapse, and rearrange branches so the map matches how your course organizes the topic.

Starts free

The Free plan includes 3 generations per month and needs no credit card to start.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain text notes, or photos of pages.

Generate the map

DeckOwl builds a mind map with main branches and sub-points drawn from your content.

Edit and explore

Rename, move, and expand nodes until the map fits what your instructor covered.

Mind maps work best when they come from the source you are studying. Start with the central topic from your lecture or chapter, let the generator pull out the main branches, then reorganize the nodes until the structure reflects how the material is actually connected.

The Free plan gives you 3 generations per month with study in the browser. Plus adds unlimited generations and exports for when you need the map outside the site.

Frequently asked questions

Do I need to install Java to run FreeMind?

FreeMind is a Java application, so it needs a compatible Java runtime installed on your computer. Check the release notes for the version you download before you install it.

How do I study from a mind map instead of just rereading it?

Cover the sub-points of one branch and try to recall them from the branch label alone. Then check your answers against the source notes and redraw the map from memory.

Can I use DeckOwl without downloading anything?

Yes. DeckOwl runs in the browser, and the Free plan includes 3 generations per month with no credit card needed to start.

What does the paid plan add?

Plus costs $39/year or $7.99/month and adds unlimited generations plus PDF, DOCX, Anki, and CSV exports with spaced repetition. Pro, at $14.99/month, adds a stronger AI model, bulk upload, and QTI 2.1 and Moodle XML export.
