Expand a branch to drill from a theme down to a specific fact, cause or government scheme.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of a page. Text recognition reads scanned pages too.

Generate the map

DeckOwl organizes the material into a central topic with main branches and sub-branches you can explore.

Edit and study

Adjust the branches to match your syllabus, then keep studying the same material with flashcards or quizzes.

DeckOwl does not hand you a ready-made printable chart. It builds the map from your own PDFs, DOCX files, PPTX slides or photographed pages, so the branches follow the notes and sources you already use.

Every branch is editable, so you can prune topics outside your syllabus and attach your own examples. The same upload can also produce flashcards and quizzes when you want to test recall.
