What's the line. If they use Microsoft word or grammarly to ease the process is that OK? Both of which use AI. Is there anyone in the world who isn't using this tech even before an editor looks at it?

For me, an important distinction is whether or not a human is reviewing the edits suggested by an AI.

I toss all of my work into Apple Pages and Google Docs, and use them both for spelling and grammar check. I don't just blindly accept whatever they tell me, though; sometimes they're wrong, and sometimes my "mistakes" are intentional.

I also make a distinction between generating content and editing content. Spelling and grammar checkers are fine. Having an AI generate your outline is questionable. Having AI generate your content is unacceptable.
