99% translation dictionaries and grammars from what I have seen. AI does not really translate, it does not understand the context but can sort of fake understanding the languages in a very technical sense which works well enough when you don't know the language at all but loses all the nuance.
Edit: 99% is a bit hyperbolic, AI has a good amount of human translations to work off of as well which helps it with idiomatic/figurative language but it is still not translating, just playing the odds.
