There are startups trying to quantify what "works" for novels [1]. Of course they're just scraping the barest surface of what "works" means as of yet with attempts to analyse pacing and use of different word types and how characters are described etc.

I've tested some while writing my own novel, and it was more "interesting" than useful at this point, but I might give it another shot with novel #2 to contrast and compare the two.

It'll be interesting to see how those tools evolve, though.

[1] authors.ai is one example.
