Wow! Nice work again!
I decided to try out the Lesson Translator on a Korean video that only had TL text, and the translation seems pretty darn good.
So far as I can tell (as a beginner and with the help of DeepL—free version, lol). There was one awkwardly worded sentence, but the translation is strong.
This is impressive!
P.S. I’ll have to work with it more, but I wanted to share my initial thoughts. (Just Wow! 
) Where are the free translations sourced from?
