They're both tools that use spaced repetition [1].

The OP made it sound like Hickory is automatically generating cards based on what a user reads. It also sounds like Hickory is doing more analytics. Of course, Anki is open-source, so it could be augmented to do these.

The analytics are definitely useful. I re-read it and it does seem like Hickory automatically divides any text into flash-cards. Not sure how effective that is in reality though.
