Since we are talking about Emacs now, there's a package[1] for Anki just like everything else in Emacs. :)
This basically connects to a background server of Anki, you create a card and press C-c C-c to send it to Anki. End of the day, just sync it.
I am one of those guys who try moving everything to Emacs, but personally I found Anki to be much better than org-drill just for the simple reason that I can go through the cards quickly using the phone app when I have some time (waiting for someone, something, etc.). With org-drill I have to be in front of my machine.
But yeah, I've pretty much sold to org-mode. I, too, have been creating a knowledge base inside org-mode. This contains the deeper knowledge and explanations, while the tidbits are in Anki. Org mode notes are like fat nodes, and Anki cards are the threads which bind them. I personally have found both to be very useful together.
One of the problems with this approach (one-way sync/extract from org-mode files to Anki database) is losing out the context (imagine org file notes from a technical books). I use org-drill in combination with org-sticky-header, which show the path of headings to that particular node. Normally in Anki, this requires to add some extra descriptions or tags for this purpose. In org-mode, we get this for free.
But on the other hand, org-drill will fill your org file with scheduling and metadata drawers (I did some hacks to hide them but not able to make it work without messing the org-ellipsis).
Another drawback with org-drill is it manages schedules for one "card" per heading, hence cloze items are not scheduled individually. So, either you remember entirely "Alfred North Whitehead wrote [Principia Mathematica] in [1910]" or not at all. In Anki, not only the book title "[Principia Mathematica]" and the written year "[1910]" are tested separately (same as org-drill), but also scheduled/scored separately too (where org-drill falls short).
I use both, org-drill mostly for books, Anki for "standalone" facts. But I'm always wishing for some kind of a system that hit the sweet spot between them two.
