European AI that keeps data local – but can it handle my obscure two-letter words?

A new AI service that promises data stays under European law. I'm curious how it handles the Scrabble dictionary – are the word lists stored on EU servers? Would it be proud of 'qi' and 'za' or would it flag them as errors? I'd like to test it, but I suspect the training data is too generic to know the strange edges of English.
