Turn lecture notes into a mind map you can edit
Upload slides, PDFs, or typed notes and DeckOwl creates a mind map with the main ideas as branches. Edit it, explore it, and see how each lecture topic connects.
How a lecture mind map helps you study
Lectures move fast, and linear notes can hide how one idea supports another. A set of mind maps from lecture notes shows the structure at a glance, with the main topic in the center and each subtopic branching outward.
- Start with the lecture's main topic in the center of the map.
- Add major sections as first-level branches and supporting facts beneath them.
- Keep each branch to a short phrase so the map stays readable.
- Revisit and edit the map after each lecture to add new connections.
Starts from your own notes
Upload a PDF, DOCX, plain text file, or a photo of handwritten or printed pages. Text recognition reads the photos.
Editable map
Rename, move, or delete nodes so the map matches how your instructor framed the lecture.
Explorable branches
Expand and collapse branches to focus on one section at a time, then review the whole structure.
How it works
Upload your lecture notes
Add a file or a photo of your notes. No credit card is needed to start.
Review the generated map
The central topic and main branches appear, with supporting details beneath each one.
Edit and study from it
Adjust the structure, then use the map to quiz yourself on how the ideas connect.
Seeing the connections before an exam makes it easier to recall details under each heading. Editing the map as you review the material also keeps it aligned with what your instructor emphasized.

Frequently asked questions
How do I organize lecture notes into a mind map?
Put the lecture's main topic in the center, then add the major sections as first-level branches. Place supporting facts, definitions, and examples beneath the branch they belong to.
How many branches should a lecture mind map have?
Most lectures work well with four to seven main branches. If one branch grows past about six subpoints, split it into two smaller branches.
Can I edit the mind map after it is generated?
Yes. The map is editable and explorable, so you can rename, move, or delete nodes and expand or collapse branches.
Can I export a lecture mind map?
The free plan lets you study in the browser without exports. Plus includes PDF and DOCX export, along with unlimited generations.
