> Use Anki

Anki is great for studying, but the card creation experience sucks. To be specific: I found creating any custom card type immediately dropped me into the bowels of CSS. It felt like writing HTML by hand.

Is there any facility for re-using shared pieces?

I felt like it needed a static site generator type tool to move up a layer of abstraction and reduce the copying of chunks into my card. Is there one? Please mention if so.

It's rather nerdy, but QuickTurtle9 released mdfc on GitHub, https://github.com/bttger/markdown-flashcards a couple of years ago

Using that as the input file format standard, AI can generate what you're looking for, Android app, Webapp, iOS app, pdf.
