No time/resources or interest in extensively editing your book? Here are simple ways to refine your book in 10 minutes tops (Using ChatGPT). It is meant for surface level enhancement that will nevertheless go a long way. It does not cover how to come up with a good story, only how to improve your existing one on a sentence-level basis (though I might do a similar book for how to write/come up with a good story). Feel free to add your own tips and thoughts in the comments (I might make a chapter addressing those in detail)
