About the price
Questions.
What is the difference between the two books?
Length only. The short book runs 8,000–10,000 words (about a 45-minute read); the full novella runs 25,000 words across 20 chapters. Both are delivered the same way: a PDF and EPUB to download, plus a private share link.
Is it a subscription?
No. The book prices are one payment for one finished book. There is no recurring charge for ordering a book.
How does the PH20 code work?
Enter PH20 at checkout for 20% off either book until 31 December: $23.20 for the novella, $15.20 for the short book.
What if I read the book and don't like it?
You read the finished book before it is shared and can ask for changes. Nothing reaches your recipient until you approve it. Refunds and revisions are covered in the refund policy.
Can I read a real book before I pay?
Yes. The library has 39 complete books from the same pipeline, the first two chapters of each free with no signup. Sign in to read the rest, free.
What are the developer plans for?
They are for people embedding the engine themselves through the MCP server, from $9.99/mo. The plans buy access, not books: you bring your own model key and no hosted book is included. If you want a book written for you, you do not need them. See developers.
