Cheating? What test or game are you playing that it might be considered cheating? Honestly, I feel it's a legitimate tool to build applications and it can help teach you along the way. If you can stomach using a Microsoft tool then Bing Chat might be an even better option. It's the same technology with a better, IMO, data set.
I've used mine to prop up monitors but lately they just sit on my shelf. Books that serve no purpose end up in the garbage simply because I don't have room for them.
