Claude won't write the scene your book builds to?
The romance, the fight, the dark turn the whole plot leads up to: AIWriteBook writes it. Explicit fiction is allowed on every plan, and each chapter follows your outline, your characters and a sample of your writing, until it is a book you can publish.
Sounds familiar?

its voice is quite recognizable … that style leaks through

Worried about switching?
- Will it soften the scene I actually need?
- No. Explicit and adult fiction is allowed on every plan, including free. Romance and dark scenes are written as your outline asks. Only books set up as Children's, YA or Non-fiction are kept clean.
- I already pay for Claude. Am I paying twice?
- AIWriteBook needs no Claude or other AI subscription. Your outline and first chapter are free, then plans start at $12/mo billed yearly, or buy a one-time pack of 250 credits for $20. Keep Claude for everything else if you like.
- Claude knows my voice. Will this?
- Paste a few paragraphs of your own writing on the Details step and every chapter is written in that style. You can also pick a different AI model for any chapter, so you are never stuck with one house style.
- What about watermarks and who owns the book?
- You steer every step: your outline, your characters, your style sample, and every edit is yours to accept or reject. The AI Content Detector shows which passages read as AI, and the AI Humanizer rewrites them. Export the whole book as DOCX, EPUB or PDF whenever you like.
- My drafts live in Claude. Do I start over?
- No. Paste them into one .docx file of up to 200,000 words and import it. Your characters and notes are pulled out free, and the first import is free until you buy anything.
Where Claude is better
We would rather you pick the right tool than the wrong one.
- Prose many writers love, and Projects that hold your own voice rules and long chats.
- One assistant for everything else: research, code with Claude Code, and your office apps.
- A free plan, and Pro from $17/mo billed yearly, that covers far more than books.

Questions writers ask
Does AIWriteBook allow explicit fiction?
Yes. Explicit adult fiction is allowed on every plan, including free. Romance and dark scenes are written, not refused.
Is AIWriteBook a good Claude alternative for writing a book?
Yes, if your goal is a finished book. Claude is a general assistant with usage windows. AIWriteBook keeps your outline, characters and Story Bible in one project, writes chapter by chapter, and ends with print and ebook files.
Does AIWriteBook have a 5-hour limit like Claude?
No. There is no 5-hour session window. Writing uses credits: plans start at $12/mo billed yearly, and one-time packs start at $20 for 250 credits.
Do I need a Claude account to use AIWriteBook?
No. Everything runs inside AIWriteBook. You don't connect or pay for any other AI service.
Will my book read like Claude wrote it?
Each chapter follows your style sample, and you can switch the AI model per chapter. The AI Content Detector and AI Humanizer find and rewrite passages that read as AI.
Can I publish to Amazon KDP from AIWriteBook?
Yes. The Format step on Pro gives you a print-ready PDF and a KDP wrap cover, plus an EPUB and a DOCX. You upload them to KDP yourself.
