How a study mind map maker helps you learn

Most students end up with pages of lecture notes that are hard to see as a whole. A study mind map maker turns those notes into a visual outline, so you can see how a topic breaks into causes, examples, and rules at a glance.

Start from the files you already have, including PDFs, DOCX, PPTX, and photos of pages.
Edit every branch so the map matches your course rather than a generic template.
Explore nested sub-points to review one idea at a time before a test.
Turn the same material into flashcards or quizzes when you want to practice recall.

Generate the map

DeckOwl organizes the main ideas into branches and sub-points.

A mind map is most useful when you can change it. DeckOwl builds the first draft from your PDF or notes, and you can rename nodes, move branches, and add your own connections until the map reflects what your instructor emphasized.

The free plan includes 3 generations per month and browser study. Plus adds unlimited generations and exports, so you can keep a copy of your work outside the app.

Frequently asked questions

How do I study Spanish present-tense verbs with a mind map?

Put the regular endings on one branch, then add the stem-changing and irregular groups as separate branches with a few example conjugations under each. Reviewing the branches out loud helps you recall which verbs follow which pattern.

What should a mind map for Spanish verbs include?

Good branches cover regular -ar, -er, and -ir endings, stem-changing verbs like pensar and querer, and irregular yo forms like hacer and tener. Each branch works best with a few model conjugations rather than full tables.

Is the mind map feature free?

The free plan includes 3 generations per month and lets you study in the browser. Exporting your work is a paid feature on the Plus plan, which is $99.90/year or $9.99/month.

Can students get a discount?
