I tried to use Anki a long time ago, but maintaining cards ended up being too toilsome. Now that we have ChatGPT and other AI tech to take some of the pain out of that, I might give it another try for language study.
I do however maintain that for many skills it’s better to memorize processes over facts, and develop a more nuanced embedding with natural repetition intervals, rather than overfitting via excessive Anki-fication.
