My biggest problem with anki is that the isn't a nice way to make cards. There's a vscode plug-in that lets you do markdown but it's too limited and clunky last time I used it.
org-mode has some spaced repetitions tools (e.g., org-drill). I personally don't recommend SR by flashcards too much. It's better to do it more naturally. For example, read books regularly to learn a language; common words will repeat themselves enough times that they'll effectively be a form of SR.
