And the problem with Reddit--especially with certain language communities--is you'll get a hallucination rate higher than current LLMs because learners can either overestimate their knowledge or sound off just because they want to show off.

I don't recommend LLM use for beginners at languages but once they get a semester or two (or the equivalent) under their belt, the instant access to an answer that's right most of the time is invaluable. Just first get to the point where you can start to recognize "maybe that's not quite right..." first, and check sources. And definitely check in with natives as much as possible.
