About this app

Codex AI Book Writer turns an idea into a finished book.

HOW IT WORKS

1. Describe what the book should be about. A paragraph or two is enough - say who it is for and what they should get out of it.
2. Codex AI plans the chapters and sections. You read the outline before anything is written, and you can reword or remove any line you disagree with.
3. When the outline is right, Codex AI writes it. You can close the app; the writing continues, and the book is waiting in your library.
4. Read what came out, correct any section, and export the result.

EXPORT

Finished books can be exported as PDF, Word (.docx), EPUB, or a web page. The file opens on your device, and you can save or share it wherever you keep your work.

TOKENS

Writing costs tokens, based on the length of the text produced. Token packs are available in the app, and you can also redeem a code bought on codexleo.com. Your balance and every book are tied to your account, so the same library is there whether you use the app or the website.

WHAT IT IS NOT

Codex AI Book Writer writes drafts, not final manuscripts. It is a way to get from an idea to something substantial you can edit, quickly. What it produces is yours to publish, sell, or rewrite.

What’s new

First release. Describe an idea and Codex plans the chapters and writes the book section by section. Token packs can be bought in the app.
