How a free mind map from your material works

Want a free mind map before you commit to anything? DeckOwl lets you start with no credit card, so you can test the tool on your own lecture notes or reading first.

  • Start with your own PDF, DOCX, PPTX, text, or photo of a page
  • Get a map of main branches and sub-points in one generation
  • Edit branches and expand sections as you review
  • Move from the map to quizzes or flashcards when you want to test recall

PhotosynthesisLight reactions in the thylakoids · Calvin cycle in the stroma · Produces glucose and oxygen
MitosisProphase · Metaphase · Anaphase · Telophase
OsmosisMovement of water across a membrane · Flows from high to low water potential · Solute concentration sets the direction

Built from your own material

Upload PDFs, DOCX, PPTX, plain text, or photos of pages. The text is read and organized into a map of main branches and sub-points.

Editable and explorable

Rename branches, move ideas around, and expand or collapse sections so the map matches how your course organizes the topic.

Study from the same map

Turn a branch into quiz questions or flashcards when you are ready to test recall, instead of rereading the whole page.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, text file, or a photo of a textbook page from the lecture or reading.

Generate the map

DeckOwl builds a central topic with main branches and sub-points drawn from your material.

Explore and edit

Click through the branches, fix anything that looks off, and study the map in your browser.

A good map puts the main idea in the center, then splits it into a few branches, each holding two to four sub-points. Working from your own material keeps the map tied to what your instructor actually covers, not a generic template.

The free plan includes 3 generations per month and browser study. Paid plans add unlimited generations and export options when you need the map or its content somewhere else.

Frequently asked questions

How many branches should a mind map for cell biology have?

Most topics work well with 4 to 7 main branches, each holding 2 to 4 sub-points. Fewer branches can hide structure, and too many make the map hard to scan.

What is the best way to study from a mind map?

Cover one branch, recall its sub-points from memory, then check the map. Working outward from the center tends to work better than rereading the whole page.

Can I export my mind map for free?

Exports are a paid feature. The free plan lets you study in the browser, and the Plus plan adds PDF and DOCX export.

Do I need a credit card to try it?

No. You can start on the free plan without a credit card, which includes 3 generations per month.
