Personally I'm interested in Japanese and Chinese culture and I frequently find Japanese speakers engage with my photos on Bluesky so I frequently use it to read responses and write replies where: (1) I can specify tone and context, and then (2) I use a different chatbot to translate my reply back to English to check that it translates properly.
I'll usually translate it with chatgpt and then run the result backward through Google Translate in order to double check. It's been excellent every time.
I found a few services while looking for a proper translator to turn a small phrase into Old Latin. I can't remember the services now (it was long ago) but there are professional translators, historians and college professors who moonlight on these sites doing small translations for a small fee. Some offer bulk translations of small phrases. One of the translators I got was a professor in classical text/literature/language (can't remember exactly) and another was some professor of ancient/classical history. The translations came back similar but worded a bit different because there was no way to do a 1 to 1 translation and they provided options for sightly different variants.
You're not bothering them if you're paying for the job. On your part, all you need to do is to set up a web-based interface that makes it easy and fast for them to log in and add the translations.
