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. Upload a .docx and the Book Editor returns an editorial letter, a chapter-by-chapter map and a style sheet for the book — then works through line editing and proofreading with you, one suggestion at a time.
Three passes, one manuscript
Upload a .docx, or pick a book from your library. 7 credits per 1,000 words during beta — charged once, for the whole manuscript.
Part of the AI Writing Assistant guideWatch a full manuscript go from raw draft to clean, consistent prose — import, editing pass, and change review in one walkthrough.
Professional editing isn't one job — it's three, and they happen in order. The Book Editor runs all three in a single session: the editorial review is the developmental pass, then line editing, then proofreading. You pay once, at the review.
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.
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.
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.
The accuracy pass — Proofread in the tool, and a separate run tuned for a different job. Grammar, spelling, punctuation, the tense that slips in act two, British versus American spelling. It works against the style sheet the review built for your book, so it knows which of your two spellings of a place name is the one you chose, rather than guessing chapter by chapter.
You get: fixes marked High confidence or Medium confidence, with a one-click "Accept all high-confidence fixes" for the ones that are not judgement calls.
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 you | AIWriteBook Book Editor | Freelance human editor |
|---|---|---|
| Cost per full book | 7 credits per 1,000 words during beta, charged once for the manuscript | $500 to $2,000+ for a developmental plus copy edit |
| Turnaround | The review of a full manuscript runs in minutes, not weeks | Two to six weeks, longer for popular editors |
| Revisions | Re-run any chapter as often as you like — included, no further credits | Usually one or two rounds, then it costs more |
| Remembers the whole book | The review reads every chapter and builds a style sheet the later passes enforce | Yes, but continuity slips creep in on long manuscripts |
| Keeps your voice | You accept or reject each suggestion; five-deep undo and revert-to-original per chapter | Depends entirely on the editor's taste and brief |
| The judgment call | Fast, consistent, tireless — but not a human reader | Irreplaceable 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.
Six 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.
Upload a .docx and headings become chapters — so the tool works on manuscripts written anywhere, not only books made on AIWriteBook. Already have the book here? Pick it from your library instead. You tell it whether the manuscript is fiction or non-fiction, and what language it's written in.
Before anything runs you see the chapter count, the word count and the exact price. 7 credits per 1,000 words during beta, half the regular 15, with a minimum of 7. It is charged once, at the start of the review — everything after it in that session is included.
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, anchored margin comments graded High, Medium or Low, and a style sheet for the whole book.
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.
A second, differently tuned pass over the same chapters, for grammar, spelling and punctuation. Fixes come marked High confidence or Medium confidence, so you can take the mechanical ones in bulk and read the rest. Triage from the keyboard: A accept, R reject, N next, P previous.
For an uploaded manuscript you get your own .docx back with the accepted edits patched into it — your real formatting, not a regenerated document. Alongside it: a record of what changed in this flow, chapter by chapter, and your untouched original, downloadable at any point.
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.
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.
A "What to fix first" list puts the structural problems in order, so you're not weighing a dropped subplot against a comma.
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.
"Fix with AI" on any comment takes you to that chapter with the rewrite panel already loaded on the passage in question.
Whole-manuscript comprehension, per-suggestion control, and your own file back at the end.
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.
The review builds one: Characters, Places and terms, Spellings and terms, Timeline, Facts and continuity, Style conventions. It is then fed into every later pass, which is how continuity gets enforced across chapters instead of chapter by chapter.
Line-edit suggestions are labelled Objective or Optional; proofread fixes are labelled High confidence or Medium confidence. "Accept all objective fixes" and "Accept all high-confidence fixes" clear the mechanical work so your attention goes to the calls that are actually yours to make.
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.
"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.
For an uploaded manuscript the download is your original .docx with the accepted edits patched in place, so the formatting you set up survives the edit. Your untouched original stays downloadable throughout, and a summary shows what was accepted and rejected in each chapter.
Different writers, one shared problem: the manuscript is too long for a line-by-line tool to actually understand.
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.
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.
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.
Your credibility is in the details. The style sheet records your terms, spellings, facts and timeline across the whole book, so the term you defined two ways and the figure you cited two ways surface as continuity problems rather than shipping.
I am currently testing AIWriteBook to finish one of my unfinished books, and it's been amazing! The writing quality is excellent and it even sounds like me. It's easy to use and I'll definitely be signing up.

… What I like most is that it is not just a text generator. You get a complete workflow - from the initial idea, characters and outline all the way to chapters, metadata and the cover. At the end you export files that are ready for Amazon KDP and KDP Print, in the correct formats and with the right dimensions. That takes a lot of fiddling out of the process. …

I bought @AIWriteBook to help with an existing historical novel, and my first impression is very positive. What I like most is that it isn't just a text generator. It combines manuscript import, characters, outlining, writing-style support, AI chat, chapter writing and editing in one environment. I can keep creative control while deciding how much I actually want the AI to help with the writing. …

I underestimated how helpful and useful AIWriteBook could be as a tool. When using the chapter by chapter editing, it not only suggested four ways to fix a passage, but why they were necessary. I plan to keep using this tool for a long time.

… Then there's the audiobook feature, the reason I signed up in the first place. You take a finished manuscript and, with essentially the push of a button, it produces a full, professionally narrated audiobook. Natural sounding narration, real voice options, and it's all built for a distribution ready result, not just a rough recording. …

AIWriteBook really takes most of the hassle out of writing a book. It’s designed to help you by letting you import your Word drafts and then training the AI to match your voice across all your chapters, which seemed easy and I did not have any issues. That way, your tone stays natural and consistent from beginning to end. …
Read the full review on AppSumoI have more AI tools than I can count...literally. As far as book writers go this is the best I've seen if you care about quality. There are some decent ones out there you can churn out mid quality faster with, but nothing I've found that can come close to the quality you can get with this one. Great buy for the right audience.

Great tool to help write and edit your books. I especially like the cover creator. Has really helped me make some awesome-looking covers!

I got this to make a personalised storybook for my kids. It worked well enough that I've made a few more since. The part I like is that you're not stuck with the first draft. You edit the outline, change the characters, rewrite a paragraph that reads wrong, and regenerate just that bit. Illustrations come out of the same flow, so there's no stitching images in from another tool. Export is a print-ready PDF, so the thing you end up with is an actual book you can get bound and wrapped. …

A writer's bestie, in all the ways that count. The best part is how easy it is to edit it your story, making it a complete, perfect blend that is something that's uniquely yours- integrating your own ideas, own special voice, and even unique quirks, while still enjoying the benefits of AI in all the aspects where you need it most- editing, readability, and idea prompts.

I bought AIWriteBook because I wanted a straightforward way to create and publish children's books, and there is a lot I like about the idea behind the software. I created a complete children's picture book using the platform. The book itself came together well and I was happy enough with the finished content and illustrations to actually publish it. …
Read the full review on AppSumo… It's way more app than anything else on the market. The developers clearly know what they're doing, and it fills a gap that virtually no one else does well. The inline editing is where books actually get good, and this is the first tool I've seen that takes that stage seriously instead of dumping a first draft on your desk and calling it done. …

I have tried several different tools that do specific tasks in fiction writing: editing, planning your book, formatting, writing, etc. This one tool provides these. Each function I have tried seems to provide good results and output. I am now revaluating the need of a couple of subscription-based tools I used thanks to this platform. …
Read the full review on AppSumoBeen toying with an idea for a book for about a decade, but never had the time to truly sit with it and dig in. After playing around with the settings and uploading my own style of writing as a voice, deeply impressed with how well it does keeping to my own style of writing. Already buzzing with more books in my head as i work on the first. Definitely happy i purchased.
Read the full review on AppSumo… One thing that really surprised me was when I imported an existing script that's at about 100,000 words. AIWriteBook not only did a good job at deciphering all the different characters, plots, and subplots, but to then put all of that in the correct places where they belong inside of the AIWriteBook application is just a phenomenal time saver and did a better job than the more established Sudowrite on the market. …

… Other users have already provided a detailed review, so I prefer to focus on an aspect neglected in their reviews: the audio recording options for the electronic book. Thus, I must say that the audio creation exceeds my expectations when I see the quality of the voices interpreting my fictional works (short stories) and ongoing developments (multi-voice readings). Bravo!

… The hard part comes when you read the chapter and think... this section needs to change, this part doesn't sound like me, or I want to take this in a different direction. This is where the book writing happens. AIWriteBook gets this part right. You can keep working on the chapter, make changes through the editor, regenerate weaker sections and continue refining the book instead of starting over every time. …

One charge per manuscript, at the start of the editorial review. Credits come from your plan or a one-time pack — there is no per-book editing fee on top.
Half the regular 15 while the Book Editor is in beta. Charged once, when the review starts, with a minimum of 7 credits — a 60,000-word manuscript comes to 420.
Once the review is paid for, the rest of that editing session costs nothing further — however many chapters you run, re-run, or rewrite.
What writers ask before running a full manuscript through it.
Both, as separate passes. The review is the developmental edit: it reads the whole manuscript and returns an editorial letter, a prioritized list of what to fix first, a chapter-by-chapter map with a pacing verdict, and comments anchored to specific passages. Line editing is the second pass, at sentence level. Proofreading is the third, for grammar, spelling and punctuation. All three happen in one session, in that order.
7 credits per 1,000 words while the Book Editor is in beta — half the regular 15 — with a minimum of 7 credits. It is charged once, at the start of the editorial review, and covers the whole manuscript. Every line edit, proofread, batch run, re-run and rewrite in that session afterwards is included at no further cost. A free account starts with 100 credits, which is enough to review a manuscript of roughly 14,000 words.
Close to it. Each suggestion appears in a margin rail aligned to the passage it changes, with a category and a written reason for it. You accept or reject them one by one, or from the keyboard: A accept, R reject, N next, P previous. Nothing is applied silently, there is five-deep undo per chapter, and you can revert a chapter to its original text at any point.
Only if you let it. You approve every single change, and the suggestions are pre-sorted so you can see which ones are actually arguable: line-edit suggestions are marked Objective or Optional, proofread fixes High confidence or Medium confidence. Take the objective ones in bulk, read the optional ones as opinions, and reject as many as you like.
A .docx upload, where your headings become the chapters, or a book you already have in your AIWriteBook library. The .docx route means the tool works on manuscripts written anywhere — Word, Google Docs, Scrivener exports — not only books created here.
For an uploaded manuscript, your original .docx with the accepted edits patched into it, so your formatting survives rather than being regenerated. You also get a breakdown of what changed in the flow, with accepted and rejected counts per chapter, and your untouched original stays downloadable the whole time.
No. Editing sessions are saved as you work and can be picked up on another device, and you can have several manuscripts in progress at once. Long passes can be run across the whole book with "Edit all chapters" and reviewed later — the suggestions are waiting where you left them.
Editing is one stage. Here's the rest of the path from draft to published book.
Run a final grammar and consistency sweep before you publish.
Turn an idea into a full structured draft, then edit it here.
See the whole platform — outline, write, edit, cover, and export.
Build the chapter structure before you write the draft you'll edit.
Bring in a .docx, or a book you already have here, and get an editor that reads the whole thing before it says a word about your sentences. One charge for the manuscript, and you approve everything that follows.
