Not particularly, but I have used chat GPT to explain grammatical concepts to me that baffled me before, or that baffled someone else and I, as a native speaker, was unable to explain. Works like a charm - provided a suitable prompt. Only tested with GPT4, can't say much about 3.5.

I'd be very careful with this - I've experimented with this extensively and GPT-4 gets some things horribly, horribly wrong (at least for Mandarin Chinese).

I think the best of both worlds is pairing GPT-4 with human curation (that's what I'm doing!)
