Turn your class notes into an editable AI mind map
Upload a PDF, Word file, slide deck, plain notes, or a photo of a page. DeckOwl builds a mind map you can rearrange, expand, and explore branch by branch.
Why build your study map from your own notes
A mylens AI mind map generator works best when it starts from the material your instructor actually gave you. Upload lecture slides, a reading, or typed notes, and the map follows your course's own terms and structure instead of a generic outline.
- Start from PDFs, DOCX, PPTX, plain text, or photos of pages
- Edit branch names, order, and grouping after the map is generated
- Collapse or expand sections to study one topic at a time
- Turn key branches into flashcards or quizzes for practice
Editable branches
Rename, move, or delete any branch so the map matches how your course organizes the material.
Works from your own files
Start from PDF, DOCX, PPTX, plain text, or images read with text recognition, not a generic template.
Explore at your pace
Collapse and expand sections to focus on one topic at a time instead of scanning a crowded diagram.
How it works
Upload your material
Add a PDF, slide deck, document, or notes. Photos of printed pages are read with text recognition.
Review the generated map
DeckOwl organizes the content into a central topic with main branches and sub-points you can edit.
Adjust and study
Reshape the map, then turn key branches into flashcards or quizzes when you are ready to practice recall.
Mind maps help most when you can change them. Because every branch is editable, you can merge overlapping ideas, add a missing example, or split a crowded section into smaller pieces before an exam.
The map also works as a study starting point. Explore one branch at a time, check that each sub-point makes sense, and then move the strongest ideas into practice questions.

Frequently asked questions
How do I turn class notes into a useful mind map?
Put the main topic in the center, then add the major themes as first-level branches. Use the second level for supporting facts, definitions, and examples, and keep each branch to one idea.
How many main branches should a study mind map have?
Five to seven main branches is usually easy to scan and remember. If a topic needs more, split it into two linked maps so each one stays readable.
Can I export my mind map?
Free plans study in the browser without exports. Plus, at $99.90/year or $9.99/month, adds PDF, DOCX, Anki, and CSV export along with unlimited generations.
Does it work with photos of pages?
Yes. Photos of pages are read with text recognition, so you can build a map from printed material you only have on paper.
