I've made custom flashcards for anki to study stuff and I tested this for some similar things and it was a lot faster and easier. Anki feels like it takes forever so the investment to make a custom set is only worth it for things you need to study for a long time.
If all you want is to generate a bunch of flashcards fast and you have a pdf with the info presented clearly it's an easy method.
Well, yes, in a way at least. I’m not pretending to invent something never done before.
Although it already has multiple features that Anki doesn’t have.
