Veering into off topic territory here, but to clarify, yes, Hungarian and Finnish are not among the languages that are supported here on meta for automatic translation. You can see the supported languages in the language picker in the top right corner. If you want to talk more about the automatic translation here on meta, start a topic in Site feedback.
@Enit I am super impressed with the initiative you are showing to try to get Discourse set up and configured to do all this. It’s a tremendous experiment! Please keep us informed as you move along. It would be amazing if you could write up how you did it in more detail once you have it all set up.
I know some other members here are using AI on their own sites, but I am not sure who they all are. We use AI very actively here on meta, but that initiative is led by others and I am not intimately familiar with how it is configured. I’d like to, but I also haven’t taken the time yet to set it up and start experimenting with it on other sites I maintain.
Perhaps we need a new topic in Community to congregate and just talk about the various ways people are trying to use AI in Discourse and how it’s working out for them, beyond just the technical details.
Looks like you’ve figured out how to translate yourself for participating here which is great, and you are not writing posts anymore that look like AI hallucinations! 
Just remember to stay on topic and to start new topics for new questions, and that short, clear posts are going to be easier for others to read so they can help you.
