used chatgpt to rewrite a client email and it caught something i completely missed

Was about to send a follow-up to a client who hadn't responded in a week. wrote it out, thought it sounded professional. pasted it into chatgpt and asked "does this sound passive aggressive" just to be safe. it said yes. specifically pointed out that "as per my last email" and "just circling back to make sure this didn't get lost" both read as passive aggressive even though i didn't mean them that way. the rewrite it gave me was way better. shorter, friendlier, didn't sound like i was annoyed (even though i was). client responded within an hour.
