You bring the stories and the ideas. Your GhostWriter brings the structure.
GhostWriter & the Muse is a plug-in for Claude that guides you through the entire book-writing process: planning, drafting, and revising. No writing experience needed.
Your ghostwriter is your thought partner and coach, taking your idea from start to finish. They learn how you sound, pull your stories out with the right questions, and write as much, or as little, as you want, in your voice.

Watch the 90 second tour. Sound on.
You do not need to be a writer. You know the stories, and I will help with the rest.
One thing I need from you. Tell me about a day you still think about. Where you were, who was there, what happened. Say it right here, the way you would tell a friend.
That one story shows me how you sound, and it becomes the first story in your book.
For fiction and nonfiction alike: novels, memoir, family history, business books, and practical how-to. How much you write is up to you. Write every word yourself and let your ghostwriter edit, let it draft and keep what you like, or anything in between.
Talk, write, or do both
Tell a story out loud, paste in pages you already wrote, and rewrite anything yourself. Your ghostwriter asks one question at a time and works with whatever you bring.
Your book files stay on your computer
Your book files are saved in your own folder on your computer. Claude processes your conversations. We do not receive your manuscript.
Built to flag what it is not sure of
When a chapter needs a fact or story only you know, it marks the gap and asks you. Nothing goes into the book until you approve it.
You can see your whole book while you work
You talk with your ghostwriter in Claude. Your book's pages, your outline, your stories and your voice all open beside the conversation and show where the book stands and what comes next. You can change any line yourself.
Your first paragraph earns its place. I kept every word.
The second explains what the first already showed. Cut it, or tell me why it stays.
Either way it is in chapter one now, exactly as you wrote it, and on your Manuscript page.
Choose who you write with
Some ghostwriters are gentle and some are blunt. Pick the one you want when you start, and change whenever you like. Choose the coaching style you prefer. Your book will still sound like you.

What you need to start

GhostWriter runs inside Claude, the AI assistant made by Anthropic. Their paid plan is recommended. See Claude's plans
An idea for a book
A sentence is enough to begin. If you have old drafts, talks, or notes, bring them. If all you have is what is in your head, that works too.

The guided setup shows you every click, and you only do it once. You do not need any technical skill.
Common questions
Does it write the book for me, or can I write it myself?
Either, and most people do both. Talk and let your ghostwriter draft, write a section or a whole chapter yourself and have it edit, or rewrite any paragraph on your book's pages. Your own words are always kept exactly as you leave them.
Will it sound like me?
That is the hardest part of any ghostwritten book, so it gets the most care. Your ghostwriter studies how you write or talk, drafts one section as a voice test, and learns from every change you make to it. It is built on purpose to keep to your voice. It checks its own drafts for the stock phrases that make writing sound like AI, and takes them out.
Will it make things up?
GhostWriter is built to flag anything it is not sure of. When a chapter needs a fact or story only you know, it marks the gap and asks you. Nothing goes into the book until you approve it. Like any writing assistant it can still be wrong with confidence, which is why you read every chapter before it stands (see our Terms, section 5).
What kinds of books is it for?
Books drawn from real life (memoir and life stories, family history, business and leadership books, how-to books) and novels. Tell your ghostwriter which kind you are writing in your first message, and the plan, the outline and the writing take that shape: an argument and its stories for a true book, scenes, characters and turning points for a novel.
Do I need to be technical?
No. If you can download a file and make a folder, you can set this up. After that, everything happens by talking with your ghostwriter in plain language.
Where does my book live?
In the folder you made, on your own computer. The files are plain text you can open, copy, and back up like any other document. Claude processes your conversations inside your own Claude account. We do not receive your manuscript.
What does it cost?
$29.99 at launch, paid once. That covers GhostWriter & the Muse for as many books as you want to write, and every update. There is no subscription to us. Claude is a separate paid subscription from Anthropic, and you pay them directly. That is our launch price, and it will go up as GhostWriter grows. Whatever you paid, your copy is yours.
Can I try it before I am sure?
Yes. Buy it, and for three days there is a button on your setup page that cancels your copy and sends your $29.99 straight back to the card you paid with. No email to write, no questions asked. After three days the copy is yours, and there are no refunds. Your book stays on your own computer either way.
The book you keep meaning to write can start today.
