Stuff like that doesn’t always work though, at least on free versions in my experience. I use Ai to write flowery emails to people to sound nice when I normally wouldn’t bother and I used it to negotiate buying my car. I would continually tell it not to use - dashes while writing emails. And inevitably after 1 answer it would go back to using them.

Maybe paid versions are different but on free ones you have to continually correct it.
