We've gone through tons of vendors. We've spent tons on well known vendors, we've spent pittances on shitty vendors, in the end, they all outsource to some random polyglot who either doesn't quite have a grasp on one language or the other or maybe doesn't have the whole context. For some reason, they fail to give us a good translation some percentage of the time and the communities bitch. It's a mix really and if they would do the job right the first time, it would be awesome. We're translating into a dozen languages and on a busy month, we might send out 1200 names/paragraphs to be translated.

For someone fluent in all involved languages, sure.

But from the sounds of it, OP's company outsources the translation but doesn't fully trust the output they get back. They're back to square one for verifying it, because if they knew both languages enough to verify, they could do the translations themselves.

The problem AI is trying to solve is "how do I access a skill I don't have cheaply?" It's only because it's bad at that problem that it has shifted to "how can we use AI to get more production out of the skilled workers we still need to babysit the AI that is unreliable at everything?"
