How the AI mind map maker helps you study

Starting from a 40-page lecture PDF, a mind map maker can pull out the main ideas and show how they connect in a few seconds. Instead of rewriting everything by hand, you get a starting structure you can check against your notes.

  • Central topic with main branches pulled from your material
  • Sub-points grouped under each branch so related ideas stay together
  • Editable nodes for adding your own examples and corrections
  • Browser-based study on the free plan, with exports on paid plans

Starts from your own material

Upload PDF, DOCX, PPTX, plain text, or a photo of a page. The map is built from the content you provide.

Fully editable

Rename branches, move nodes, add sub-points, or delete what you do not need before you study.

Explore at your pace

Expand and collapse branches to focus on one section at a time, then turn the same material into flashcards or a quiz.

How it works

Upload your notes

Add a PDF, Word file, slide deck, text notes, or a photo of a page.

Generate the map

The AI picks a central topic and organizes the material into main branches and sub-points.

Edit and explore

Reshape the map, then click through branches to review each idea in order.

Mind maps work best when you can change them. DeckOwl produces an editable map, so you can move a branch under a different heading, add a missing example, or remove a detail your course does not cover. Many students who already use Mindomo will recognize the workflow of branching from one central idea.

Once the map is in good shape, you can study it directly in the browser. The free plan includes 3 generations per month, and paid plans add unlimited generations and export options for when you need to take your work elsewhere.

Frequently asked questions

How do I make a good study mind map from a textbook chapter?

Start with the chapter title as the central topic, then add one branch for each major heading. Under each branch, list the key terms, causes, steps, or examples, and keep each sub-point short enough to recall from memory.

How many branches should a study mind map have?

Most chapters work well with 4 to 7 main branches, each holding 2 to 4 sub-points. If a branch needs many more, split it into two branches so the map stays easy to scan.

Can I edit the mind map after it is generated?

Yes. Every node can be renamed, moved, expanded, or removed, so you can correct anything the AI got wrong or add details from your lecture.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser. Plus costs $39 per year or $7.99 per month and adds unlimited generations and PDF, DOCX, Anki, and CSV exports.
