I mean, all the translation is made by volunteers, as far as i know. Nobody can tell for sure if they were using AI or not at this point.
I was playing with the translations and found out the game tells us how many % of it uses AI translation
I don't think machine translation means AI, but I don't know for sure
I'm pretty sure it does in this context. I know 3 languages currently, learning my 4th, and Google Translator is currently the best non-AI machine translator available and it doesn't translate nearly this well.
