The problem I've seen with trying to sell people on Anki in the outside world is that many places will give you printable flash cards. An easy way to get these into Anki would go a long way.

Coverting them depends entirely on how the cards are formatted. If you get them in some digital file you could convert them into a table and import them into Anki.

However the more I use Anki the less I think of Anki as flashcards and the more I think of it as a new medium.

With a stack of printable cards you go through the cards till you think you know them all. You usually try to review similar cards together. With Anki you don"t review similar cards together but spread them out over time.

People often want to brute force information into their brain with flashcards while Anki is primarily about making sure that you can remember what you learned.
