Language Transfer[0] will continue to be a better resource than any AI course. It’s very hard to beat a human that has put in time crafting a logical way to teach a language with the appropriate ramp ups. The Greek course on there is fantastic. And it’s free with zero ads. Best language learning tool I’ve ever used period.
Agree, it was a game changer for me with Spanish. Learning a second language is just plain hard and LT is the closest to “a breakthrough” I think we will get, but it’s still hard and people don’t like that.
