After using Grammarly across hundreds of emails, blog posts, and documents, this Grammarly review goes well beyond grammar checking.

Grammarly vs ChatGPT for writing: which is better?

Grammarly processes your text on its servers to provide suggestions, which means your writing is transmitted to their infrastructure. For personal use, their privacy policy states they do not sell user data. Enterprise and Business plans offer additional security controls including SAML SSO and admin policies for organizations with stricter requirements.
