I've produced around 6 books on various topics from investing and health, like all AI prompting systems and engines, it gives you high quality output if you give it high quality input. If you are lazy and write "write me a book about dogs" and then don't get what you want, that is really your fault. You need to be exact in specifications and even use other AI tools to generate a mile long prompt. Further, adding your own content can help it sound just like you vs too generic or vanilla. It does what it says, if it gets upgraded to write non-fiction as well, I would love that. Also would love to have the ability to write 1000-4000 word articles using the same "book building" logic the platform is already doing, especially with BYOK turned on where I am using my own AI credits anyway.
