Well, I wrote a novel last year and now I'm fighting a prequel/sequel manuscript. So I asked GPT to help me with the plot. I explained the whole plot to him first and then what I have now... He gave me a lot of "common places", clichés, uninteresting plots. A week ago I asked him how to finish a melody I was writing ---yes, I'm master of none--- but that time it was just nonsense answers. Weird because then I asked him about a math problem. He explained it very well, and when I asked for a formula...I got the right one.
