Text correction with changes highlighting

[wooden aurora]

I'm working on a small web app that corrects mistakes in user messages using the GPT-3.5/GPT-4 API and then highlights the changes it has made. There are two correction types: "just correct the grammar" and "make the text sound more natural." It works with multiple languages, and there's even a language detection option. You can try it out at https://language-challenge-react.herokuapp.com/correct (you'll need to provide an API key).
