How a free concept map helps you study

Most people who look for a free concept map generator are trying to see how a long chapter fits together before an exam. You upload a PDF, slides, or photos of pages, and DeckOwl builds a mind map with a central idea and branches you can rearrange and click through. The free plan includes 3 generations a month, and you study the results in the browser.

Free plan: 3 generations per month, studied in the browser
Plus: unlimited generations with PDF, DOCX, and Anki export
Works with PDFs, slides, notes, and photos of pages
Editable maps you can reshape as your understanding grows

Example heart anatomy mind map branches

Chambers of the heartRight atrium · Right ventricle · Left atrium · Left ventricle

Heart valvesTricuspid · Pulmonary · Mitral · Aortic

Pulmonary circulationRight ventricle pumps deoxygenated blood · Through pulmonary arteries to the lungs · Oxygenated blood returns by pulmonary veins to the left atrium

Systemic circulationLeft ventricle pumps oxygenated blood · Through the aorta to the body · Deoxygenated blood returns by the vena cava to the right atrium

Electrical conductionSinoatrial node sets the rhythm · Signal passes through the atrioventricular node · Bundle of His and Purkinje fibers spread it to the ventricles

Frequently asked questions

How many concept maps can I make for free?

The free plan includes 3 generations per month, and you can study each map in the browser. Upgrading to Plus removes the monthly limit.

How do I map the flow of blood through the heart?

Split it into two loops: pulmonary circulation, where the right ventricle sends blood to the lungs and it returns to the left atrium, and systemic circulation, where the left ventricle sends it to the body and it returns to the right atrium. Give each chamber and vessel its own branch so the order is easy to trace.

Can I export my mind map?

Export to PDF, DOCX, and Anki is included with Plus, which costs $39/year or $7.99/month. The free plan keeps your maps in the browser.

Do I need a credit card to start?

No. You can start on the free plan without a credit card and upgrade later if you need unlimited generations.
