I'm working on character.ai for learning Chinese, you chat with characters at your level, and get instant feedback on your writing. It's a way to get a wide amount of comprehensible input in an engaging way that also practices output.

This is really cool, I'm interested in this as I'm also a chinese learner and I thought about doing sometihng kinda similar (just locally)

I like the UI, really cool project.

I think the prompting might need more work to make it natural though. I just tried a "hungover chat with 996" worker, and the responses seemed to be lacking a little too much context
