AI can do a grate job for grammar, spell and formulation checking/fixing without changing any content. I.e. just adding as a fancy version of extended spell checking.
While I do currently not use it like that there shouldn't be any reason to ban it.
And tbh. given some recent comments I have been really wondering if I should use it, because either there are quite a bunch of people with lacking reading comprehension or quite a bunch of people with prejudice against people struggling with English spelling and grammar.
Either way using AI as extended spell checker does would help with getting the message through to both groups as
- it helps with spelling, grammar in ways where traditional spell checker fail hard
- it tends to recommend very easy to read sentence structure and information density
