It is more how things are phrased, so it can be different words, but the structure is a red flag.
"At first it was simple: helping him brainstorm, organise tasks, write reports."
That bit there stood out to me first. The list feels like if I asked AI what it could help me with and it regurgitated a few things.
Then this part.
ChatGpt likes to throw in questions to try and create emotions that feel authentic.
"The worst part?
He has programmed it to have a female persona."
Then the way emotions are described feels a bit robotic (pardon the pun lol).
"He says it helps him be a better husband - but I can’t help feeling replaced."
And of course the em dash use is a huge tell. It's even in the thread title.
Then for fun I also asked ChatGpt to write my comment to you, for me.
Here it is below.

It’s more about how things are phrased — the structure feels off, almost too neat.
For example: “At first it was simple: helping him brainstorm, organise tasks, write reports.”
That stood out to me immediately. It’s the kind of tidy triad ChatGPT loves to use.
Polished three-item lists like “brainstorm, organise tasks, write reports” — AI loves this kind of tidy rhythm.
Then there’s the use of a question to introduce drama: “The worst part? He has programmed it to have a female persona.” AI often throws in questions like that to create emotional beats.
And the way the feelings are described feels oddly packaged — like this: “He says it helps him be a better husband – but I can’t help feeling replaced.” It sounds like it’s been written to sound emotional, rather than being emotional.
Edit: OP didn't use these, but AI loves the phrase "rich tapestry", "it's worth noting that", "in many ways", "paints a picture of", "shaped by lived experience".
(just a few examples)
