Book Editor

An AI Book Editor That Edits the Book, Not Just the Line

Grammar checkers polish a sentence. A real edit reads the whole manuscript first: where it drags, which chapter is doing no work, whether the name you spelled two ways is the same person. Open the Edit step of your book, or import a .docx, and the Book Editor returns a genre scorecard, an editorial letter and chapter-by-chapter suggestions, then works through line edits with you, one suggestion at a time, writing each one you accept into the book.

Watch a full manuscript go from raw draft to clean, consistent prose — import, editing pass, and change review in one walkthrough.

The Edits Every Manuscript Needs

Professional editing happens in order: the big picture first, then the sentences. The Book Editor does both. The review is the developmental pass, and line edits handle style and proofreading together. You pay once per book.

First passDevelopmental Edit

The big-picture pass — the Review step in the tool. It reads the entire manuscript, then writes you an editorial letter: what the book is doing, where it stops doing it, which chapters repeat a beat, where a thread is dropped. It also builds a chapter-by-chapter map that gives every chapter a purpose and a pacing verdict, and leaves comments anchored to the exact passages that caused them. This is the edit that decides whether readers finish the book, and the one a line-level checker cannot see because it never reads past the paragraph in front of it.

You get: an editorial letter, a prioritized "What to fix first" list, before-and-after examples drawn from your own lines, and margin comments graded High, Medium or Low.

Second passLine Edit

The voice pass. Sentence-level suggestions arrive in a margin rail beside your text, each anchored to the line it changes, each carrying a category and a written reason. They are split into Objective — a genuine error or a clear improvement — and Optional, which is taste. You can accept all the objective ones in a click and argue with the rest individually, or ignore them entirely. Run it a chapter at a time, or over the whole book at once. The same pass fixes grammar, spelling, punctuation and the tense that slips in act two.

You get: line-level suggestions marked Objective or Optional, plus targeted rewrites — Tighten, Show don't tell, Punch up dialogue, or an instruction you write yourself.

AI Book Editor vs. Hiring a Human Editor

A great human editor is worth every dollar — and most self-publishers can't spend that dollar on every book, every draft. Here is the honest trade-off, not a strawman.

What matters to youAIWriteBook Book EditorFreelance human editor
Cost per full book15 credits per 1,000 words, charged once per book$500 to $2,000+ for a developmental plus copy edit
TurnaroundThe review of a full manuscript runs in minutes, not weeksTwo to six weeks, longer for popular editors
RevisionsRe-run any chapter as often as you like — included, no further creditsUsually one or two rounds, then it costs more
Remembers the whole bookThe review reads every chapter, and the later passes keep names, spellings and facts consistent with itYes, but continuity slips creep in on long manuscripts
Keeps your voiceYou accept or reject each suggestion; five-deep undo and revert-to-original per chapterDepends entirely on the editor's taste and brief
The judgment callFast, consistent, tireless — but not a human readerIrreplaceable for nuance, subtext, and market instinct

The real workflow for most indie authors: use the Book Editor to get the manuscript genuinely clean and consistent, then spend your editing budget on a human where it counts most — a final developmental read or a proofread before launch.

How the Book Editor Works

Five steps, in order, with a stepper across the top so you always know where you are. Sessions save as you go, so you can close the tab, come back on another machine, and keep several manuscripts in progress at once.

Step 01

Source

Open the Edit step of your book, between Chapters and Metadata, or import a Word .docx in the Book Editor under Tools, which turns the file into a real book on AIWriteBook with headings as chapters. That way it works on manuscripts written anywhere, not only books made here. You tell it whether the manuscript is fiction or non-fiction, and what language it's written in.

Step 02

Cost

Before anything runs you see the chapter count, the word count and the exact price. 15 credits per 1,000 words, with a minimum of 15. It is charged once per book, when you unlock editing. Everything after that for the book is included, forever. Before you unlock, it edits your first page for free.

Step 03

Review

The editor reads the manuscript end to end and comes back with an editorial letter, a "What to fix first" list, before-and-after examples from your own text, a chapter map with a pacing verdict for each chapter, and anchored margin comments graded High, Medium or Low, all written with the whole book in view.

Step 04

Line edit

Work a chapter at a time, or hit "Edit all chapters" and let it run the book — three chapters at once, cancellable, with a retry on any chapter that fails. Suggestions land in the margin next to the line they change. Accept, reject, or select a passage and ask for a rewrite.

Step 05

Finish

Every edit you accept is already in your book. Go on to your cover, metadata and formatting, or, if you started from a .docx, download the edited file.

How the Review Step Finds Structural Problems

The errors that sink a book are almost never typos. They're the middle third that loses momentum, the plot thread that gets dropped, the stakes that never actually rise. These are structural, and a tool that only sees one paragraph is structurally blind to them. The review reads every chapter before it says anything, which is why it can tell you that chapters nine and eleven are doing the same job — and then show you the lines that prove it.

Pacing, chapter by chapter

The chapter map gives each chapter a stated purpose and one of three verdicts: Drags, Steady or Rushed. The shape of a sagging middle is visible at a glance.

Priorities, not a wall of notes

A "What to fix first" list puts the structural problems in order, so you're not weighing a dropped subplot against a comma.

Comments anchored to your lines

Every margin comment quotes the passage it refers to and carries a High, Medium or Low severity — no vague advice you can't act on.

A fix button, not just a verdict

"Fix with AI" on any comment takes you to that chapter with the rewrite panel already loaded on the passage in question.

What Makes It a Book Editor, Not a Grammar Add-On

Whole-manuscript comprehension, per-suggestion control, and your own file back at the end.

Nothing Changes Without You

Every suggestion sits in the margin until you accept or reject it, and each one comes with a category and a written rationale. Triage from the keyboard — A accept, R reject, N next, P previous. Five levels of undo per chapter, and "Revert chapter to original" if a pass went somewhere you didn't want.

Consistency Across the Whole Book

The review reads every chapter first and keeps track of your characters, places, spellings, timeline, facts and style conventions. Every later pass works from that, which is how continuity gets enforced across chapters instead of chapter by chapter.

Objective and Optional, Marked Apart

Line-edit suggestions are labelled Objective or Optional. "Accept all objective fixes" clears the mechanical work so your attention goes to the calls that are actually yours to make.

Targeted Rewrites

Select any passage and rewrite it with a preset — Tighten, Show don't tell, or Punch up dialogue on fiction — or type the instruction yourself. You see the suggested rewrite before it goes anywhere near the chapter.

Run the Whole Book at Once

"Edit all chapters" runs the current pass over the entire manuscript, three chapters concurrently, with live per-chapter status. Cancel it mid-run, retry a chapter that failed, and review the suggestions whenever you're ready — they're waiting where you left them.

Your Real Book, or Your Own File

Accepted edits are written straight into your book, so Metadata, Format and Publish work on the edited text. If you imported a .docx, the last step offers Prepare for publishing or Download .docx, and the download is your original file with the accepted edits patched in place, so the formatting you set up survives the edit.

Who Edits a Whole Book This Way

Different writers, one shared problem: the manuscript is too long for a line-by-line tool to actually understand.

KDP Publishers on a Cadence

Shipping titles on a schedule means editing can't take a week per book. Upload the .docx, take the review, run the two chapter passes, download the same file with the edits in it — and keep your release rhythm without a freelance invoice on every launch.

Reviving an Old Draft

That manuscript that's been in a drawer for two years is full of problems you've gone blind to. The editorial letter and the chapter map give you an outside read of it in an afternoon, with the specific passages attached.

Genre Fiction Writers

Romance, fantasy, thriller — each has conventions and a register. You declare the book fiction up front, and suggestions arrive split into Objective and Optional, so a deliberate fragment or a dialect spelling is something you keep, not something that gets corrected out from under you.

Nonfiction and Self-Help Authors

Your credibility is in the details. The editor reads the whole book and keeps your terms, spellings, facts and timeline consistent across chapters, so the term you defined two ways and the figure you cited two ways surface as continuity problems rather than shipping.
