Show HN: Nativish, an app to help language learners

It's basically grammarly for any™ language. It's geared towards helping middle and advanced speakers get past that point where you can express yourself but you still come off awkward and clearly non-native.

Backend is Rust (Loco/Axum) with some NLP libraries and a bunch of LLM calls. Frontend is Vue and there's a chrome extension that we're just cleaning up before releasing.

Me and my wife made the app in part because I get nervous about communicating in French in her family's group chat then realized it might actually be a good tool in general.
