Mind maps built from your own material

Lecture slides and textbook chapters pile up faster than most people can sort them. An AI mind map maker app can read a PDF or your notes and lay out the main ideas as a branching map you can follow.

Start with a central topic and let the AI pull out the main branches.
Reorganize branches by hand when the structure does not match your course.
Check each sub-point against your source before an exam.
Turn the same material into flashcards or quiz questions when the map is done.

Example periodic table group mind map branches

Alkali metals (Group 1)Very reactive · One valence electron · Soft, low density · React vigorously with water

Alkaline earth metals (Group 2)Two valence electrons · Less reactive than Group 1 · Form 2+ ions · Examples: magnesium, calcium

Halogens (Group 17)Seven valence electrons · Form 1- ions · Highly reactive nonmetals · Examples: fluorine, chlorine

Noble gases (Group 18)Full outer electron shell · Very unreactive · Monatomic gases at room temperature · Examples: neon, argon

Transition metals (Groups 3-12)d-block elements · Often form colored compounds · Variable oxidation states · Examples: iron, copper

Generate the full set

Branches from your own material

Drop in a lecture PDF, a Word document, a PowerPoint deck, or typed notes. The main ideas become branches and the supporting details become sub-branches.

Editable and explorable

Rename nodes, move branches, or add your own points. Click into any branch to see how the ideas connect.

Study from the map

Turn the same material into flashcards with spaced repetition or quizzes with explanations, all from one upload.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file, or a photo of a page. Photos are read with text recognition.

Generate the mind map

DeckOwl organizes the content into a central topic with labeled branches and sub-points.

Edit and explore

Adjust the layout, fix anything the AI missed, and study the map in your browser.

A map works best when it reflects your course rather than a generic template. Because DeckOwl builds the map from the files you upload, the branches match the headings, terms, and examples your instructor actually used.

The free plan includes 3 generations per month and browser study. Plus, at $39/year or $7.99/month, removes the generation limit and adds PDF, DOCX, Anki, and CSV exports, so you can take your map out of the browser.

Frequently asked questions

How do I organize a mind map for the periodic table groups?

Put the periodic table at the center and give each group its own main branch. Under each group, list the shared traits, such as valence electrons, reactivity, and common examples.

How many main branches should a periodic table mind map have?

Five to eight main branches usually works well. For the periodic table, the alkali metals, alkaline earth metals, halogens, noble gases, and transition metals make a clear set.

Can I edit the mind map after it is generated?

Yes. You can rename nodes, move branches, and add your own points so the map fits how you study.

Is there a free plan, and what does it include?

The free plan includes 3 generations per month and studying in the browser, but no exports. Plus costs $39/year or $7.99/month and adds exports, and students get 40% off with a school email.
