The demo article only had a couple translations, so we auto-translated some missing ones. Sorry the Turkish one isn't great!
Most of the app we try to encourage you to use professionally translated works to learn whichever language you're studying, so try to do as we say not as we do :D
As I’ve commented elsewhere, to the extent you are using machine translation: note that GPT is bad at translation to languages other than English. Telltale sign is not declining for gender. I saw this a lot with GPT4’s Polish. Better to use one of the standard translation services.
