Fair enough. My last exposure to Grammarly was pre-ChatGPT, when it was a lot closer to vanilla spellcheck.
But I think it's actually not all that different, particularly in the context of "essays teach writing." It used to be human work to analyze sentences for passive voice, remember the difference between there/their/they're, and understand how commas work, but now the computer handles it.
(Relevant sidenote: Am I using commas correctly here? IDK! I've never fully internalized the rules!)
