Don’t think that’s a great idea
Chat GPT tends to make stuff up
When I asked it to spoil the ending of one of my favorite novels, it created new nonexistent characters (the book had alternate personas of the main villain which were scheming against him, but Chat GPT created multiple new alternate personas for the main villain which in reality never existed) with secret and brilliant plans that changed everything
When I asked it to spoil the ending of my favorite video game, it 1) created new in reality nonexistent machinations for one of the protagonists explaining how she was able to manipulate one of the antagonists in an extremely convoluted way when in reality this sequence of plans / events never happened and the two characters have no relationship, and 2) stated that the main villian was secretly haunted by the memory of his father the entire time and this is why he enacted his sequence of plans. There is another really convoluted reason as to why the villain did everything he did, but his father has absolutely nothing to do with it.
