Editable branches
Rename, move, or add nodes so the map matches how your course organizes the material.
Explore one branch at a time
Move through the map section by section while you review, instead of scanning a crowded page.
Works from your own files
Upload PDFs, DOCX, PPTX, plain text, or photos of pages, which are read with text recognition.
How it works
Upload your notes
Add a PDF, DOCX, PPTX, text file, or a photo of a page from your textbook or handout.
Generate the map
DeckOwl builds a mind map of the main topics and the supporting points under each one.
Edit and explore
Adjust the branches so they fit your course, then move through the map to review each topic.
The free plan gives you 3 generations a month and lets you study in the browser, which is enough to test the workflow on a real chapter. Exports to PDF and DOCX are part of Plus, so plan around that if you need a file to print or share.
