How to write a book
with AI
A complete workflow for authors, from a one-line idea to a finished book on Amazon and beyond.
Writing a book with AI means describing your story idea and letting an AI model draft, structure, and format the manuscript while you guide and edit it. With Infinite Library you go from a one-line premise to a publishable book in four steps: build your universe, write the draft, format and polish, then publish and sell. A first draft can be ready in roughly 10 minutes, and finished books distribute to Amazon, Barnes & Noble, Ingram, and Shopify through the Lulu Direct integration. You can start writing for free — no credit card — and pay only when you want more AI credits or clean, print-ready exports.

One workspace vs. a stack of tools
A typical book project spreads across several apps. Infinite Library handles each stage in one place.
| Stage | Typical separate tool | Infinite Library |
|---|---|---|
| Outline & world-building | Notes app or spreadsheet | Persistent series world |
| Drafting | Word processor | AI drafting plus editor |
| Formatting | Layout software | Auto print & EPUB output |
| Cover | Designer or design app | AI cover generator |
| Distribution | Separate KDP / retailer setup | Lulu Direct to Amazon & more |
Every book starts with one idea.
From a single premise to a finished manuscript — here is how the four steps fit together.
