I will soon be release a number of books on a vast variety of things, thanks to the ChatGPT. While I have written and published books long before this was an option. I've also done ghostwriting, and that is a of cleaning up language while trying emulate the voice and adding fluff when necessary. I actually find ghostwriting a lot easier, even if it's unfinished when I get ahold of it, than to write something completely off the top of my head (and i'm a pantser too).
Utilizing a series of prompts, I have the AI write a book for me. Now I know that bring up so much controversy, cause the AI isn't that great of a writer. Which is why I call this version of the book, "Draft 0". I then go through and rewrite the whole thing, and make sure it follows along with the message I want.
For instance, the first (and only book so far) I did this with, "Creative Guidance to Productivity Tactics: Prompt Engineering", I had it write the book, which was over 600 pages, so I narrowed it down to about 100. As I rewrote it, I added content (a section on Emojis), and it's now about 150 pages. (not trying to advertise, just using it as an example of Collaborate and Transparency). In fact, while you can see my name in the Jenga blocks on the cover, it's officially authored by Christopher GP Templeton (in my Custom Instruction the AI refers to itself as Chandler GP Templeton, yes I named my AI) to showcase that we together wrote the book, but I final words mine not the AI.
Being able to take something it wrote under my guidance and then rewrite it, I can produce books a lot faster. Since that time of my last book's release, I actually have a number of books at the Draft Zero stage.
