In short, for me anything that is using AI in a way that adds value to what you are going to contribute would be an acceptable use.
If there is consensus on suggestions you make I will post them in the OP.
You can copy/paste what AI says, as long this is not the only content in your post and you explicitly quote it, so everyone knows you didn't create that content.
I use AI a lot, specially for coding. BUt you need to let everyone knows it was AI generated.
