Turn your notes into a visual mind map you can explore
Upload a PDF, slide deck, document, or photo of your notes and get a clear map of the main ideas and how they connect.
Why a map helps you remember
Seeing how ideas connect is often what makes a topic click, and a visual mind map app puts that structure on screen where you can follow it.
- Start from your own lecture slides or textbook chapter instead of a blank page.
- Keep each branch to a few short sub-points you can recall from memory.
- Use the map to quiz yourself by covering branches and rebuilding them.
- Edit the map after generation so it matches your course terminology.
Any source material
Upload PDFs, DOCX, PPTX, plain text, or photos of pages. Text in images is read with text recognition.
Editable branches
Rename, move, or add branches so the map matches how you think about the topic.
Explore at your own pace
Expand and collapse branches to focus on one section at a time without losing the big picture.
How it works
Upload your material
Add a PDF, document, slides, notes, or a photo of a textbook page.
Review the generated map
DeckOwl organizes the key ideas into a central topic with labeled branches.
Edit and explore
Adjust the map, then study the branches or export it if you are on a paid plan.
Mind maps work well for subjects with many linked parts, such as cell biology, history timelines, or case studies. A map shows which concepts belong together before you memorize the details.
Because the output is editable, you can correct anything the AI missed and keep the map as a living study guide that grows with your course.

Frequently asked questions
How many branches should a mind map for cell biology have?
Most topics work well with 4 to 7 main branches, each with a few sub-points. Keep sub-points short so you can recall them without looking at the page.
How do I study from a mind map?
Cover the sub-points and try to rebuild each branch from memory, then check your answer against the map. Revisit weak branches a day or two later.
Can I edit the mind map after it is generated?
Yes, the map is editable, so you can rename, move, or add branches. Exporting your work as a PDF or DOCX is available on the Plus plan.
Is there a free plan?
Yes, the Free plan includes 3 generations per month and studying in the browser, but exports require a paid plan. Plus is $39/year or $7.99/month.
