Make a Windows mind map from your own notes

Sorting a week of Windows lecture notes into branches is slow on a blank page, so a free mind map tool for Windows should start from your material instead. DeckOwl reads PDF, DOCX, PPTX, text, and photos of pages, then builds an editable map you can reshape and explore.

Generate the full set

Starts from your material

Upload PDF, DOCX, PPTX, plain text, or a photo of a page, and the map is built from what you actually wrote or were given.

Editable branches

Rename, move, or delete branches so the map matches your course outline instead of a generic template.

Explore at your pace

Expand and collapse branches to focus on one section of a Windows topic at a time, then review it in the browser.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, text file, or photos of pages on your Windows computer.

Generate the map

DeckOwl reads the material and proposes a main topic with branches and sub-points.

Edit and explore

Reshape the branches, then open each one to check it against your source notes.

The free plan includes 3 generations per month and studying in the browser, with no exports. Mind maps sit alongside flashcards with spaced repetition and quizzes with explanations, so you can move from the map to practice without retyping anything.

Plus costs $39 per year or $7.99 per month and gives unlimited generations, plus PDF, DOCX, Anki, and CSV export. Students get 40% off with a school email.

Frequently asked questions

What should the main branches of a Windows mind map cover?

Start with the parts you will be tested on, such as the file system, boot process, Registry, and user accounts, then add sub-points under each. Keeping each branch to two to four sub-points makes the map easier to review.

How do I check a mind map against my source notes?

Open the section of your notes behind each branch and confirm it matches a heading or definition there. Then quiz yourself on any branch you cannot explain from memory.

Is this mind map tool free on Windows?

The free plan gives you 3 generations per month and lets you study in the browser, and no credit card is needed to start. Unlimited generations are part of the Plus plan.

Can I export my mind map?

Export options such as PDF, DOCX, Anki, and CSV are Plus features, and the free plan does not include exports.
