VPN for sure slows one down. Without VPN with me the translation tool still frequently doesn't work.
I do believe, even though a translation tool has been used, the writing style + feelings placed into the content can be noticed as being written by humans.

If it comes to writing to you, I have to correct a lot if I use a translation tool. Phrases, but also words we use in poetry and which mean something to us, referring to stories we wrote, will the translator mess up (remove or change for something else).

I never used Grok or Chatgpt to translate anything. I don't know how. It is deepl or Google translate although the last one is more vulgair but tends to translate literally unlike deepl these days plus it works in all those cases deepl refuses. It likes the more popular AI vocabulary way more plus American English.
It is also able to translate more languages, like Bengali, unlike deepl.
