Frequently asked questions

How do I organize the causes of the American Civil War in a mind map?

Start with a central node for the war, then add branches for long-term causes such as slavery and sectional tensions. Add short-term triggers like the 1860 election as separate sub-branches so the sequence stays clear.

How many branches should a mind map for a history unit have?

Most units work well with 4 to 7 main branches, each holding 2 to 4 sub-points. Fewer branches keep the map readable when you come back to review it.

Is there a free plan?

Yes, the free plan includes 3 generations per month and lets you study in the browser. Exports to PDF, DOCX, or Anki require a paid plan.

Can I upload notes or photos of pages?
