Ask the AI to check a name, date or detail across every chapter, get a reader's take and a proofread, and keep the edits you agree with.
The Glasshouse is a 26-chapter mystery. Its greenhouse clock stops at ten past four in chapter 3, but chapter 24, where the solution turns on it, says twenty to five.
The stopped clock
The clock above the fern beds had stopped at ten past four. Frost had crept across the inside of the glass.
Nell wrote the time down before anyone could wind it again. Her father had kept the magistrates’ records for thirty years, and he always said the first thing to write down was the time.
The greenhouse clock stopped at ten past four. Does every chapter agree?
Chapter 3 and your timeline say ten past four; chapter 24 says twenty to five. I’ve proposed a fix there for you to review.

Read this chapter as a first-time reader. Where does it lose you?
The stopped clock pulls me in. I drift where her father’s advice breaks in, just as the scene moves. Your text is intact.
Cut her father’s advice. Keep the rest as I wrote it.
The glass door
“The clock stopped at twenty to five,” Nell said. “Whoever stopped it wanted us to think that was when Julian died.”
“The clock stopped at ten past four,” Nell said. “Whoever stopped it wanted us to think that was when Julian died.”
Edwin didn’t answer. Behind him the glass door stood open to the frost.
“You’re gonna tell them,” she said. “Or I am.”
Proofread this chapter.
Two things to check: 1. Wording, paragraph 3: “gonna” in Nell’s line; “going to” unless it’s her voice. 2. Spelling, paragraph 6: “lead the way” should be “led the way”, the past tense. Nothing in the chapter has changed yet.
Sample novel; interface drawn from current Muses components.
The examples come from The Glasshouse. With a memoir, a business book or a practical guide, the same work runs on your own names, dates, figures and chapters.
Ask whether a name, a date, a figure or a spelling holds everywhere. The AI can look through every chapter and your notes, reread what it turns up and quote the lines that disagree next to each other.
Ask it to tighten a scene, cut a digression or fix a date that drifted, and it can draft the change one paragraph at a time, in the chapter you're reading or one you haven't opened. A dot in the chapter list shows where a change is waiting.
Pick Review & Suggestions and the AI answers the way a candid reader would, about the open chapter or just the lines you've selected: where it holds, where it drifts, and a few changes worth making. Your text stays as it is.
Choose Proofread and get a numbered list of slips in the open chapter or your selection: typos, grammar, punctuation, word choice, consistency. Each one quotes the words, suggests a fix and says why. Name the ones to fix and it can draft just those.
Tell it the clock stopped at ten past four, Nell's backstory waits for chapter 12 and "gonna" stays in her lines. It can save notes like these for you, for the book or for one chapter, and bring them into later sessions. Open the list any time to edit or delete one.
The AI's changes to your existing chapter text are marked in place. Keep or reject each edit, or all of them together; a rejected edit leaves your sentence as it was. Each finished review is saved as a version of the chapter to compare or go back to.
You decide, change by change. When it edits text you've already written, the change appears marked in the paragraph; reject it and your sentence stays exactly as it was. Review & Suggestions and Proofread are set up to answer with notes, not edits. Tell it what to protect, like the way a character talks, and it can keep that as a note for later sessions. Text it writes into an empty or new chapter goes straight in, and a chapter title it changes can too.
One upload can hold 200 files and 50 MB, room for a long book split into chapters; a larger folder can come in after you sign in, with Import Project on the Muses home page. The AI doesn't read the book cover to cover in one go: it looks up what your question needs and rereads those chapters. On a long book, ask about one thread at a time and give it a last read yourself, because it can overlook a mention.
Your browser encrypts the contents of your files before they're uploaded. To finish the import, create an account or sign in within 30 minutes, in that same browser; the book then shows up in your account as a project and the encrypted upload is removed. Once the 30 minutes are up, the upload can't be opened any more, so you'd pick the files again. After import, you can download the book as DOCX, Markdown or TXT at any time. How Muses handles what's in your account is set out in the privacy policy.
Yes. Signing up, bringing in your book and editing it by hand cost nothing, and the free plan comes with AI credits every month. Paid plans come with more. Following a detail through many chapters uses more credits than a quick question; the pricing page lists current plans.
Yes. The chapters of a memoir, a practical guide, a business book or narrative nonfiction arrive as you organized them, with no folders added. The checks just change shape: a figure quoted in two places, a date, the spelling of a source's name, a term you defined early on. Ask about each one across the book, get a reader's take on a chapter, then proofread it. Keep research or a style sheet in a folder of its own; the AI can look through it together with the chapters.
DOCX, TXT and Markdown (.md) files, a whole folder or one ZIP. Resave a .doc file as DOCX first; PDF isn't supported, and images in a DOCX are left out. Each file becomes one chapter and folders keep their shape; Muses doesn't break a file up at its headings. So separate chapter files work better: the AI can search a single long file and propose paragraph edits in it, but Review & Suggestions and Proofread aim at one chapter at a time. Numbers in front, like 01_The palm house.docx, set the order and are dropped from the title. An unusually long single file may be skipped.
It checks continuity, drafts line edits and proofreads, but it doesn't do a developmental edit: it won't score the book or its readability, set it against bestsellers or write an editorial letter on the whole manuscript, and its feedback comes a chapter or a passage at a time. It can't open EPUB files or lay out a print edition. Exported DOCX files carry no tracked changes or comments, you can't install it as a plugin in another editor, and it isn't a grammar checker that underlines errors while you type. Export a DOCX when it's time for beta readers or a human editor.
Start with a detail you changed halfway through, like a person's name, a date or the time on a clock, and ask the AI to check it in every chapter. Then ask for a reader's take and a proofread.
