Why a free mind map helps on a MacBook

A free mind map for MacBook is most useful when your notes have grown past a single page and you need to see how the ideas connect. DeckOwl builds one from a PDF, DOCX, PPTX, text file, or a photo of a page, so you can start from material you already have instead of drawing branches by hand.

Upload from your MacBook: PDF, DOCX, PPTX, text, or page photos
Keep the central topic in the middle and one branch per major concept
Limit each branch to two to four sub-points so the map stays readable
Revisit and edit the map after each lecture to keep it current

MitochondriaSite of cellular respiration · produces ATP · double membrane with cristae · has its own circular DNA

MitosisProphase · metaphase · anaphase · telophase with cytokinesis

PhotosynthesisLight-dependent reactions · Calvin cycle · chloroplast location · produces glucose and oxygen

Endoplasmic reticulumRough ER with ribosomes · smooth ER and lipid synthesis · protein transport · detoxification in liver cells

Map from your own material

Upload PDF, DOCX, PPTX, plain text, or images of pages, and the main ideas become branches.

Editable and explorable

Rename, move, and expand branches so the map matches how your course organizes the topic.

Works in your browser

Study on your MacBook without installing anything. The free plan covers 3 generations per month.

How it works

Upload your notes

Add a chapter, lecture slides, or a photo of handwritten pages from your MacBook.

Review the branches

Check the main topics and sub-points, then reshape any part that does not fit.

Explore and study

Click through the branches to see how ideas connect, and revisit the map before a test.

The map stays editable and explorable. You can reorganize branches, expand a topic into sub-points, and check how one concept leads to the next before you test yourself. Working from the same source file keeps the map tied to what your course actually covers.

The free plan includes 3 generations per month and studying in the browser on your MacBook. Exports such as PDF, DOCX, Anki, and CSV are part of the Plus plan at $39/year or $7.99/month, and students get 40% off with a school email.

Frequently asked questions

How do I organize a biology chapter into a mind map?

Start with the chapter's main topic in the center, then add one branch for each major concept. Break each branch into two to four sub-points, such as structures, functions, and examples.

How many main branches should a study mind map have?

Five to seven main branches usually fit on one screen and stay easy to scan. If a branch needs more than four sub-points, consider giving it a separate map.

Can I make a mind map on my MacBook for free?

Yes. The free plan includes 3 generations per month and studying in the browser, so you can work from a MacBook without paying. Exports are part of the Plus plan.

Which files can I upload to build a mind map?
