Which method do you prefer to get UX copies of grammar suggestions?

It depends on the situation and the user's preferences. For example, if the user is experienced in editing copy and wants to have complete control over the grammar and style, then using a manual review process may be the preferred method. However, if the user is not as experienced and wants an automated solution, then using an AI-powered grammar checker may be the better option. Ultimately, the best method will depend on the user's individual needs.
