Turn your notes into a free mind map you can edit
Upload a PDF, slides, or typed notes and get a branching mind map of the main ideas and their sub-points, ready to rearrange and explore in your browser.
Why a custom mind map beats a generic template
When a chapter has forty pages of dense notes, a free mind map maker website can show how the ideas connect before you memorize any of them. DeckOwl builds the map from your own material, so the branches reflect your course rather than a generic template.
- Upload PDFs, DOCX, PPTX, or plain text notes
- Photos of pages are read with text recognition
- Maps stay editable and explorable in the browser
- Free plan includes 3 generations per month with no credit card
Upload your own material
Drop in a PDF, DOCX, PPTX, plain text notes, or a photo of a page. Text recognition reads scanned pages.
Editable and explorable
Rearrange branches, expand sub-points, and follow how ideas connect instead of reading a flat list.
Study in the browser
The free plan lets you build and study maps online with 3 generations per month and no credit card.
How it works
Upload or paste
Add a PDF, a slide deck, or your typed notes.
Generate the map
DeckOwl turns the material into a branching map of main topics and sub-points.
Explore and edit
Open branches, adjust the layout, and keep the parts you need.
Ready-made maps can work as a starting point, but they rarely match your lecture order or your textbook. Generating one from your own PDF or notes keeps the structure aligned with what you will be tested on.
Start with a main question, such as why the Civil War began, then check whether each branch answers it. Gaps in the map usually show you which section to reread.

Frequently asked questions
Is this mind map maker really free?
Yes, the free plan includes 3 generations per month and lets you study in the browser. No credit card is needed to start.
How detailed should a Civil War mind map be?
Keep each main branch to a single cause, battle, or outcome, with two to four sub-points underneath. Put dates and names on the lower branches so the top level stays readable.
Can I export my mind map?
Exports are paid features, so file exports such as PDF and DOCX require the Plus plan at $39/year or $7.99/month. The free plan keeps your maps in the browser.
How should I review the causes of the Civil War using a map?
Cover the sub-points and recall them from each main branch, then check your answers. Revisit the weak branches a day or two later to strengthen recall.
Keep exploring the topic
