Pretty good, I wish it replaced the original text instead of writing the translation beside it.

works like a charm

It doesn't translate super chats, but it's great if you're a fan of vtubers.

It will translate future chat messages after you've entered a livestream, but will not translate messages that were sent before you entered. Still damn good though.

쓸만은 한데 원문 유/무 기능이 있으면 좋겠습니다.

Actually do what it says, translate live chat messages. You just install and go to livestream and it will start doing it's thing, that's it.
