Hi Product Hunt 👋

I built PDF Occlusion because I study veterinary medicine from dense lecture notes and wanted to start memorizing quickly without spending hours rewriting every fact into separate question-and-answer flashcards.

The workflow is deliberately simple:

1. Upload the PDF or exported notes you already use.

2. Draw boxes over the facts you need to recall.

3. Review one occlusion at a time while keeping the whole page visible.

4. Choose Again, Hard, Good or Easy, and FSRS schedules the next review.

It works in the browser and can be installed as a PWA on desktop, iPhone and Android. Your library, folders and review progress stay synced across devices.

This is the first public release. I would especially value feedback from people who study from lecture slides, exported Notion notes, manuals or other information-dense PDFs:

**Where does the upload → cover → review workflow still feel slower or less clear than it should?**

Thank you for trying it. I will be here throughout launch day to answer questions and fix any launch-blocking problems.
