A mind map shows how a concept relates to its causes, examples, and exceptions, which is harder to see in a linear list. Editing the map as you go also makes you process the material again.

Start with your own lecture notes or course readings. The map is built from your material, so it reflects what your instructor actually covered.

Frequently asked questions

How should I organize Spanish present-tense verbs in a mind map?

Group them by pattern: regular -ar, -er, and -ir verbs, stem-changing verbs, and irregular yo forms. Putting one pattern on each main branch makes the rules easier to recall.

How many verbs should one mind map cover?

Keep each map to one pattern or one unit so it stays readable. Split a long list into several maps, each with 8 to 12 verbs and their key forms.

Can I export my mind map?

Mind maps can be studied in the browser on the free plan. Exports such as PDF and DOCX are part of the Plus plan at $39/year or $7.99/month.

Is there a way to try it before paying?

Yes. The free plan includes 3 generations per month and no credit card is needed to start. Students with a school email get 40% off paid plans.
