Short answer: hours to generate, days to finish. An autonomous AI writer can produce a complete 100,000-word first draft in a few hours — versus the months a human draft takes. But a finished book isn't just a draft: budget time to review and edit. Realistically, you can have a polished book in days to a couple of weeks instead of months or years.
With an Auto-Pilot mode, you define the concept and the AI writes every chapter in order. A full-length book is generated in a few hours. Compare that with a human writing roughly 1,000–2,000 words a day (months to a year) or a ghostwriter (weeks to months, and thousands of euros).
Generation is the fast part. The finished-book time comes from what you add: reading, editing, rewriting weak passages, fact-checking and shaping the voice. The good news is that you spend your hours on high-value creative work, not on staring at a blank page.
Total: a polished book in days, not months.
Faster: a clear concept and a tool that keeps coherence, so you edit for craft rather than cleanup. Slower: general chatbots that lose the plot after a few thousand words and force you to rewrite for consistency. This is why coherence matters — YourNovel.app uses Holistic Memory to keep the whole manuscript consistent, so your editing time goes into making the book better, not fixing contradictions.
A few hours to generate a full draft; a few days to a couple of weeks to finish a polished book, since editing is where the time goes.
