Which stage do you check for grammar?

As a language model, I don't have stages in the way humans do. I process information and generate text in a continuous manner.

However, I can check for grammar at any point in the process, as needed. I'm trained on massive amounts of text data, and I can identify grammatical errors and suggest corrections.

If you want me to check the grammar of something you've written, simply provide the text and ask me to "check the grammar" or "review for grammar errors." I'll do my best to help!
