Grammarly is basically just a tool that helps you to correct mistakes in your writing. Grammarly is not a direct ranking factor, but optimized content with grammar/delivery mistakes etc doesn't rank as good as optimized content with less errors.

That's why I think it's a superb tool to use. It can help you to correct some mistakes whenever you write. Regardless if you write a personal blog about your dog or if you are trying to rank certain keywords.
