I went to Thailand a few years ago to do a research project for school. One of the requirements before leaving was taking a two month intro to Thai course. I used Anki to make flashcards, and they worked pretty well. Apparently I was the only person to realize that digital flashcards existed and when I sent them out to the rest of the class everyone loved me after that, haha. Didn't end out learning that much Thai but the cards served their purpose in helping me pass the class. I especially liked the feature that let you play a sound clip for both the question and answer. Given the tonal nature of Thai it was great to have sounds accompanying each card.
