Something I wasn’t expecting with ChatGPT is its non-trivial use in gamifying ‘the blank page’.
As a non-writer sounding board you can feed it some half-thought-through notion for a story, ask it to produce an outline or where to start, then essentially find ways to do the opposite.
If it produces a standard, formulaic approach to an idea, you can then tear that apart, or invert it. You can much more easily see your story, the one that it wouldn’t tell.
