Has anyone tried a PDF to quiz ai tool for studying?

I’m prepping for finals and have a ton of PDFs I need to turn into practice questions. Has anyone actually used an AI quiz generator from a PDF? Wondering if they’re worth the time.

To be fair, they work prety well for basic recall. Honestly, the simplest thing to try first is just dropping the PDF into NotebookLM or ChatGPT and asking it to quiz you before paying for any dedicated tool.
