How a mind map template becomes your own branches

A mind map branches template gives you the right shape, but the empty boxes still have to be filled with what your course actually covers. Starting from your own lecture slides or chapter notes means each branch reflects the terms and emphasis your instructor used.

  • Start from your PDF, DOCX, PPTX, notes, or photos instead of a generic layout
  • Keep three to seven main branches so the map stays readable at a glance
  • Use sub-branches only where your source breaks an idea down further
  • Edit every label so the map uses your course's own vocabulary

Branches from your material

The AI reads your source and proposes main branches for its major ideas, then sub-branches for the details under each one.

Editable and explorable

Rename, move, or delete any branch so the map matches how your course organizes the topic, then expand or collapse sections as you review.

Study from the same map

Turn the same material into flashcards with spaced repetition or quizzes with explanations when you are ready to test yourself.

How it works

Upload your notes

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

Generate the mind map

DeckOwl creates a central topic, main branches, and sub-branches from the content you provided.

Edit and explore

Adjust the branches, then move through the map to see how each idea connects to the rest.

Good branches follow a simple rule: the central topic sits in the middle, main branches hold the major categories, and sub-branches hold the facts that explain each category. When the source is a long reading, the AI does the first pass of sorting so you can spend your time checking whether the structure makes sense.

The free plan lets you make three generations per month and study in the browser. Plus adds unlimited generations and exports, so you can take a finished map into other tools.

Frequently asked questions

How many main branches should a mind map have?

Most maps work well with three to seven main branches, one for each major idea in the source. If you find more, group related ideas under a shared parent branch.

What belongs on a branch versus a sub-branch?

Put major categories on main branches and the details that explain each category on sub-branches. Keep each label to a few words so the map is easy to scan.

Can I export my mind map?

Exports such as PDF and DOCX are paid features on the Plus plan at $39/year or $7.99/month. The free plan lets you study in the browser with 3 generations per month.

Do I need a credit card to start?

No credit card is needed to start. Students get 40% off with a school email.
