Turn your notes into a free online mind map you can edit
Upload a PDF, a set of typed notes, or a photo of a textbook page. DeckOwl drafts a branching map of the main ideas that you can explore, reorganize, and edit.
Why students use a free online mind map maker
Most mind maps start as a blank page, which is hard when a lecture has forty slides and a dense chapter. This free online mind map maker reads your source material first, then proposes the central idea and the main branches so you start from structure instead of a blank canvas.
- Works with PDF, DOCX, PPTX, plain text, and photos of pages
- Editable, interactive maps you can reshape as you learn
- Free plan with 3 generations per month, studied in the browser
- Students get 40% off with a school email, and no credit card is needed to start

Frequently asked questions
How do mind maps help with memorizing biology topics?
A mind map shows how a topic breaks into parts, such as a cell into its organelles and each organelle into its functions. Seeing those links makes it easier to recall the whole topic, not just isolated facts.
How many branches should a study mind map have?
Most useful maps have 4 to 7 main branches, each with 2 to 4 sub-points. If a branch grows much larger, split it into its own map so each one stays readable.
Is the free plan really free?
Yes, the Free plan includes 3 generations per month and studying in the browser. No credit card is needed to start.
Can I export my mind map?
Exports are a paid feature. Plus includes PDF, DOCX, Anki, and CSV export, and Plus is $39 per year or $7.99 per month.
