DeckOwl runs in the browser, so you can open a map on a school laptop without installing software. The free plan gives you three generations a month and study in the browser, while exports such as PDF and DOCX come with Plus at $39 a year or $7.99 a month.

A useful study map usually starts with one central topic, then gives each major concept its own branch with two or three supporting details. Cover the sub-points and try to rebuild each branch from memory, then check the map to find the gaps.

Frequently asked questions

Do I need to download an app to make a mind map?

No. DeckOwl runs in your browser, so you upload your material and work on the same page without installing software. Exporting files such as PDF or DOCX is a paid feature on the Plus plan.

How many branches should a study mind map have?

Most topics work well with 4 to 8 main branches, each holding 2 to 4 supporting points. If a branch grows beyond that, split it into sub-topics so each one is easier to recall.

What is the best way to study from a mind map?

Cover the sub-points, rebuild each branch from memory, and compare it with the original. Revisit the branches you missed in later sessions, spacing the reviews over several days.

Is there a free plan?

Yes. The free plan includes three generations per month and studying in the browser, and no credit card is needed to start. Unlimited generations and exports come with Plus.
