AI book writer

One sentence in. A whole book out.

Describe your book. BookArc pitches a title, plans the chapters for you to change, then writes every chapter in order, each one building on the last.

  • You approve the plan first
  • 18 languages

1 · Describe it

One sentence is enough.

Write the idea in your own words. Stuck on a blank page? Three example ideas are there to start from.

  • Add who it’s for, a tone (6 to pick from, or describe your own) and anything it must include. All optional.
  • Choose an ebook or a coloring book.
  • Describing the book is free.

2 · Shape the plan

Pick a title, then edit the plan.

BookArc works out what kind of book it is and pitches three titles. Then it plans the chapters, and you change anything before a word is written.

  • Three titles, each a different pitch. Try three more for 1 credit.
  • The book type, language, genre and reader are filled in, and all yours to change.
  • Rename, reorder, add or cut chapters, and set any chapter from 300 to 2,000 words.

3 · Write it

Written in order, each chapter knowing the last.

Press Write the book and the chapters land one after another, on the page you’ll read them on.

  • After each chapter, a summary of what it covered goes to the next, so it builds on earlier advice instead of repeating it.
  • Stop any time. Chapters already written are kept, and the book carries on from where it stopped.
  • Each chapter is priced by its length: about 3 credits for 1,000 words.

4 · Make it yours

Read it, edit it, download it.

The finished book opens as a book, with its cover. From there it’s yours to change and to sell.

Questions about the AI book writer

How long does it take?

The title and the chapter plan arrive in about twenty seconds. After you approve the plan, chapters are written one after another and appear on the page as they land, so you can read chapter one while chapter four is still being written.

Is the book ready to publish as it comes?

It is a solid, structured first draft. For a guide on a subject you know, it is close after your edit: check the facts, add your own examples and make the voice yours. A novel is more of a starting point, because voice matters more there. The AI book writer guide goes through this honestly.

Does it remember what earlier chapters said?

Yes. After each chapter, a short summary of what it covered is handed to the next one, so later chapters build on earlier advice by name instead of repeating it. In a novel it carries the characters, the setting and where the story stands.

Can I leave while it writes?

Yes. Chapters already written are saved as they land. Come back to the book and it carries on from where it stopped, or offers to.

Who owns the book?

You do. BookArc takes no rights over what it writes for you and no cut of what it earns. Sell it, give it away, put your name on it, or rewrite every line.

Which languages can it write in?

18, including right-to-left languages like Arabic. Pick the language on the plan screen, before the chapters are written.
