Online translator between Slavic languages, not Google Translate?

Question

Machine translation from one language to another

I translate with Googletranslate from Russian, for example, into Serbo-Croatian. The feeling that he first translates from Russian into English, and then from English into Serbo-Croatian. As a result of such a trip to Malakhovka through Paris, the polite you/do is replaced by you/do, and then by you/do. And by the way, for some reason, only in about half of the cases.
Are there any translators specifically around the Slavic languages, taking into account the levels of formality?
Or is it possible to somehow adjust the formality levels in Google Translate?

In the same place, ML, if it does not know how directly, then it seems to translate through the "meta-language". Test deepl.com is considered "smarter", though there are fewer languages
