Arrival

We moved in above the bakery the winter I turned seven. The ovens started at four, and the whole building smelled of it by five.

My brother carried the flour sacks two at a time, to show he could.

Read chapter one as a reader would. Where does it drift?

It holds at dawn in the bakery. It drifts in the middle, where the move is explained, not shown. I haven’t changed anything.

Where does Tom still appear?

The fire

The fire started in the flue on a Sunday, the one morning the ovens were cold.

That was the fire in 1995, and my brother was the one who ran for the neighbors.

That was the fire in 1994, and my brother was the one who ran for the neighbors.

Nobody talked about it again until the insurance man came.

Proofread this. Check the year against The ovens.

Read complete[Article] The ovens

Two slips: 1. Paragraph six: “its” should be “it’s” 2. 1995 here; The ovens says 1994.

1994 is right. Fix it.

02What it does

Help that works across the whole book

Take a 22-chapter memoir about growing up above the family bakery. You renamed your brother Sam for privacy, but he's still Tom in a few chapters, and the bakery fire is in 1994 in chapter 4 and 1995 in chapter 19. Here's how that edit goes in Muses.

Find a name or a date in every chapter

Ask where Tom still appears. The AI can search all your chapters and notes and show you the passages it finds, chapter by chapter. Dates, figures and recurring phrases work the same way.

It rereads the chapters that matter

Chapter 4 says 1994; chapter 19 says 1995. The AI can go back to both chapters, quote the two lines side by side and ask you which year is right.

Changes proposed in the exact paragraph

Tell it 1994 is right, and it can propose that fix in chapter 19 and a Sam for each Tom it found, paragraph by paragraph, even in chapters you haven't opened. Chapters with changes waiting are marked in the chapter list.

It remembers what you've settled

It can keep short notes about the book: Sam, not Tom; the fire was in 1994; the bakery chapters are in present tense. It brings them into later sessions, and you can read, change or delete every note.

A reader's response, then a proofread

In the chat, pick Review & Suggestions for a candid reader's take on the open chapter: where it holds attention, where it drifts. It leaves your text alone. Pick Proofread for a numbered list of spelling, grammar, punctuation and consistency slips in that chapter or a selected passage, each with a fix you can ask for.

You decide on every marked change

The AI's edits to chapter text you've written appear as marked changes. Accept or reject them one at a time or all at once; finishing a review saves a version, and each chapter's history lets you compare and restore.

03FAQ

Worth knowing before you bring your book in

Is it only for novels?

No. A novel, a memoir, a how-to guide or a business book comes in the same way: your chapters, in your folders, with nothing added. Create folders of your own for research, sources, character notes or a style sheet, and the AI can search them alongside the chapters.

Can it check the whole book, or only one chapter at a time?

In the chat, the AI can search every chapter for a name, a date or a detail, read the passages it finds and propose fixes across several chapters. Review & Suggestions and Proofread work on the chapter you have open or a passage you select. It looks up what each question needs, so on a long book, ask about one name or date at a time.

Will the AI change my writing without asking?

Changes the AI makes to chapter text you've already written show up as marked changes for you to accept or reject. The exception is an empty chapter: if you ask the AI to write there, the text goes straight in. Version history lets you go back either way.

Which files can I bring in?

DOCX, TXT and Markdown, as single files, a folder or one ZIP: up to 200 files and 50 MB per upload, 10 MB per file. Save .doc files as DOCX first; PDFs aren't accepted, and images inside a DOCX aren't imported; a short placeholder marks where each one was. For a bigger library, sign in and use Import Project on your Muses home page.

My whole book is one DOCX. Can I bring it in as it is?

Yes. It comes in as one long chapter, because Muses doesn't split a file at its headings, and the AI can still search it and propose edits paragraph by paragraph. Review & Suggestions and Proofread work on the open chapter or a passage you select, so one file per chapter makes those passes easier; numbered names like 01_Arrival.docx keep the order. Only an unusually long single file may be skipped.

What happens to my files before I sign in?

They're encrypted in your browser before they upload. Sign in or create an account in the same browser within 30 minutes and the book becomes a project in your account; the encrypted upload is deleted once the import finishes. After 30 minutes it can no longer be imported, so choose the files again. Once imported, the book stays yours: in the web version, export it as DOCX, Markdown, TXT, PDF or EPUB whenever you like.

Does it replace a professional editor?

No. Muses is for the edit you do yourself. Do it before an editor reads the book, so their time goes to the bigger questions, or as your main pass when hiring one isn't in the budget yet. The judgment calls stay with you.

How do I get the edited book to my editor or beta readers?

Export it. The whole book comes out as one DOCX or PDF, or as a ZIP with a file per chapter in the folders you set up; in the web version, Markdown, TXT and EPUB work too. Send it the way you'd send any manuscript, so their notes land on a clean draft.

What does it cost?

Creating an account and importing your book are free, and so is editing by hand. The AI uses monthly credits: the free plan includes some each month and paid plans include more; see the pricing page for current plans.

Catch what slipped through before anyone else reads it

Upload the chapters you have, sign up free and start with one question: a name that changed, a date that moved, a chapter that drags. Keep the fixes you agree with, then export when it reads right.
