Turn your notes into a simple online mind map
Upload a PDF, a document, or a photo of your notes and get a mind map you can edit and click through to see how each idea connects.
Why a simple map helps when a chapter is long
When a chapter has forty headings and you need the big picture, a simple online mind map shows how the ideas connect without reading every page again. Seeing the central topic with its branches makes it easier to spot what belongs together.
- Start from your own PDF, document, or photo of notes instead of a blank page.
- Edit branches so the map matches the way your instructor framed the topic.
- Explore sub-points to check your understanding before an exam.
- Use the free plan to try it, and upgrade only if you need exports.
Built from your material
Upload PDF, DOCX, PPTX, plain text, or images of pages. Photos are read with text recognition, so your own notes become the map.
Editable and explorable
Rearrange branches, expand the sub-points, and follow the links between ideas instead of scanning a long wall of text.
Free to start
The free plan includes 3 generations per month and studying in the browser. No credit card is needed to begin.
How it works
Add your notes
Upload a file or paste plain text from your lecture notes or textbook chapter.
Generate the map
DeckOwl pulls out the main topics and organizes them into branches with sub-points.
Edit and study
Adjust the branches to match your course, then explore the map or turn it into flashcards and quizzes.
Students often start with a blank page and struggle to decide where to begin. Generating the map from your own material gives you a starting structure that you can change, so you spend your time checking the content rather than building the layout.
