Skip the blank Visio template and map your own notes
Upload a PDF, DOCX, PPTX, text file, or photo of a page, and get a mind map built from your material that you can edit and explore in the browser.
Why a custom map beats a generic template
A blank diagram is slow to fill when the material already exists, and a free Visio mind map template gives you a layout but not your content. You still have to read, sort, and label every idea yourself.

Built from your material
The mind map comes from your own lecture slides, textbook chapters, or notes, so the branches match what you need to learn.
Editable and explorable
Rearrange branches, expand or collapse sections, and drill into sub-points instead of filling in a fixed layout by hand.
Turn maps into study tools
Use the same material to generate flashcards with spaced repetition or practice quizzes with explanations.
How it works
Upload your notes
Add a PDF, DOCX, PPTX, plain text file, or a photo of printed pages. Photos are read with text recognition.
Generate the mind map
DeckOwl organizes the material into a main topic with branches and sub-points you can adjust.
Edit and study
Reshape the map as you learn, then switch to flashcards or a quiz on the same content.
DeckOwl starts from your files instead. You upload a chapter or set of notes, and the tool proposes a main topic with branches and sub-points that you can edit, reorder, or collapse as you review. The map stays explorable in the browser, so you can test yourself on each branch rather than just looking at a picture.
The free plan includes 3 generations per month and browser study with no exports. If you need files for other tools, the paid plans list PDF, DOCX, Anki, and CSV exports, and Pro adds QTI 2.1 and Moodle XML.

Frequently asked questions
Does DeckOwl provide a free Visio mind map template?
No, DeckOwl does not supply ready-made Visio files. It generates a mind map from your own PDFs, notes, or images, and the free plan includes 3 generations per month.
How many main branches should a study mind map have?
Most useful maps have 4 to 7 main branches, each covering one concept from the material. Split a branch if it holds more than about five sub-points, so each one is easy to review.
Can I export a mind map to Visio?
Visio is not among the listed export formats. Plus includes PDF, DOCX, Anki, and CSV exports, and Pro adds QTI 2.1 and Moodle XML, while the free plan allows studying in the browser only.
How do I build a mind map from lecture notes?
Start with the main topic of the lecture, then add one branch per major idea. Under each branch, list the terms, steps, or examples that support it, and check that each branch can stand on its own.
