Branches from your own material

DeckOwl reads your document and sorts its ideas into a main topic with supporting branches, so the structure follows what you actually wrote.

Editable and explorable

Rename branches, reorder them, and expand or collapse sections to focus on one part of the topic at a time.

Works from photos too

Snap a page of handwritten or printed notes and text recognition pulls the content in, so you do not need to retype anything.

How it works

Add your source

Upload a PDF, DOCX, PPTX, plain text, or an image of your notes. No account setup is needed to try it.

Generate the map

DeckOwl builds a mind map with a central topic and linked branches drawn from your material.

Explore and adjust

Edit labels, move branches, and click through sub-points to test your understanding before you move on to flashcards or a quiz.

A mind map shows how causes, events, and people connect, which is hard to see in a linear summary. Seeing those links on one page makes it easier to spot gaps in your notes and to remember how ideas relate.

The free plan covers three generations a month and lets you study in the browser. Exports to other formats are part of the paid Plus plan.

Frequently asked questions

How do I make a useful mind map of the French Revolution?

Start with one central node such as the Revolution itself, then add main branches for causes, key events, and outcomes. Put one event or idea per sub-branch and check that each link reflects a real cause or consequence.

How many branches should a mind map have?

Most study maps work well with four to seven main branches, each holding two to five sub-points. If a branch grows much larger than that, split it into its own map so it stays readable.

Is the free plan enough to try this?

Yes, the free plan includes three generations per month and lets you study in the browser. You do not need a credit card to start.

Can I export my mind map?

Exports are part of the paid Plus plan, which is $39/year or $7.99/month and includes PDF, DOCX, Anki, and CSV export. Students get 40% off with a school email.
