For the past year or so I've been trying to learn German, and the most difficult part in language learning is certainly vocabulary learning. The existing apps do a pretty good job at helping with vocabulary learning, with the only issue that creating the flashcards is a big time sink. Initially the idea was to have a pool of words one wants to learn, and then the app would just quiz the user and try to maximize the learning of the user. Context: When learning new vocabulary, it is very useful to learn words in context, for example pictures and related words. If we could group related words and pictures together, the learning would (ideally) be more efficient.
