Turn any PDF into a spaced-repetition memory test

PDF Occlusion turns the notes and slides you already use into active-recall practice. Upload a PDF, draw boxes over the facts you need to remember, and review each answer while keeping the full page visible for context. Rate each recall Again, Hard, Good or Easy and FSRS schedules the next review. Your PDFs, folders and progress sync across web, desktop PWA and mobile.
