Upload a PDF, DOCX, PPTX, text file, or photo of a page and get a mind map you can edit and explore branch by branch.
Making a mind map step by step
Students who are new to mind mapping often ask about how to make a mind map in NotebookLM because it is one of the tools they already use. The core method is the same in any app: put the main topic in the center, add the major themes as first-level branches, and then add supporting facts as smaller branches off each theme.
- Start with one central topic and no more than six to eight main branches.
- Use headings from your slides or chapters as first-level branches.
- Keep sub-points factual and short so the map stays readable.
- Redraw or edit the map after each study session to test what you remember.
Works from your own files
Upload PDFs, Word documents, slides, plain text notes, or photos of pages, which are read with text recognition.
Editable branches
Rename, move, or remove branches so the map matches how your course organizes the material.
Explore at your own pace
Open each main branch to see its sub-points, then turn the same material into flashcards or a quiz.
How it works
Add your material
Upload your lecture slides, reading, or notes. Plain text works too.
Generate the mind map
DeckOwl builds a branching map of main topics and sub-points from the content.
Edit and review
Adjust the branches, then explore the map to check you understand each connection.
The slowest part is usually sorting the material into themes. Start by skimming your notes or reading for headings and repeated terms, since those often become your main branches. Keep each branch short, with one or two words or a brief phrase, so you can scan the map quickly when you review.
If you want a map built from your own files without copying text by hand, DeckOwl can generate one from a PDF, DOCX, PPTX, or notes file. You can then edit the branches and use the same material to build flashcards or quizzes.
