Allow me to mention my project Ankivalenz[1], which turns structured HTML files into Anki decks. I use it with Quarto[2][3] to generate my Anki decks. Instead of having an unorganized "pool" of Anki cards, I can create hierarchical, well-organized notes and turn them into an Anki deck. This makes it easier to create Anki decks, but more importantly, it makes it easier to keep Anki decks up to date.
