When I use Anki, all I'm doing is pressing buttons (I don't have it make me type in answers; I have no urge whatsoever to lie to it about whether I got the right answer) so I don't miss not having Vim.
When I make any more than four or six new cards at a time, I do it in Vim or write a program to do it. Anki can import CSV files.
Yeah, on further thought making and reviewing the cards are disparate enough activities that the import workflow should work fine.
