Is there a flashcard maker from PDF for my lecture notes?

I’m a student with lecture notes saved as PDFs and need to turn key points into flashcards without retyping everything by hand. Is there a flashcard maker that can work from PDFs?

had the same thing last month. i just copy the important parts from the pdf into a word doc and then make the cards from there. tbh nothing fully automatic that i know of without extra steps. still beats retyping the whole thing though.
