Streamlined AI-powered book writing

Hey Sumo-lings! 👋

I'm Mykyta, co-founder of AIWriteBook.

Before anything else, I'm an author. I've published two books. The first I wrote the long, lonely way, before AI could hold a paragraph together. The second came during the AI era. So I know both sides of this: I know what it costs to finish a book alone, and I know exactly how it feels to ask AI for help and get back... slop. Same phrases, flat dialogue, a voice that belongs to nobody. If you've ever tried a "type an idea, get a book in one click" tool and closed the tab feeling a bit insulted, I've been there, and you're not wrong.

And the draft was never really the problem anyway. Even when AI hands you 40,000 words, you still have to make them sound like you, and after that you're alone again with the formatting, the cover, the KDP metadata, the audiobook, reaching actual readers. The AI tool is long gone by then.

I'm also an engineer, and so is Artem, my co-founder. In summer 2025 we built an AI writing pipeline for ourselves and used it to produce books for NanoReads, our own reading platform. Real books, in front of real readers (more than 103,000 ATM), where slop gets ignored in about four seconds. That forced us to solve the hard part: keeping the author's voice through outline, chapters, and edits, not just generating words. At some point we realized the pipeline was writing better books than anything we could find on the market. A few writer friends asked to use it. They stayed. So at the end of 2025 we opened it to everyone.

Today a bit more than 1,300 authors and small publishers pay for AIWriteBook, more than 50,000 books have been written with it, and we hold a 4.6 on Trustpilot. One reviewer put the common thread better than I could: "it actually learns my specific style. Once you teach it your 'voice,' it feels like a genuine writing partner." Another, who has published over 250 books, called it the best AI writing software they've used. That's who we build for: people who can tell AI slop from their own writing.

What makes AIWriteBook different:

1. Your voice, not AI slop. Upload your existing books or drafts and AIWriteBook learns your characters, plot, pacing, your dialogue style, and your chapter rhythm.
2. The whole pipeline, one tab. Outline, chapters, covers, formatting, print-ready and KDP-ready export, audiobooks, book translation, and a public author page with reader email capture you own.
3. You stay the author. You edit the outline before a single chapter is written. You regenerate, rewrite, or hand-edit any chapter. Fiction, non-fiction, book series, and illustrated visual books (children's books, cookbooks, comics) are all first-class.

Can't wait to read what you publish.

Q: How can we use AI to alter a page/chapter/book

I do not want to trigger a rewrite I want to gently bring in a new character, change a scene, a location etc. and I want to keep tabs on the changes please

Founder Team

Mykyta_Founder_AIWriteBook

Sep 24, 2026

A: Hi,

Yes. That is what the AI chat editor in the Writing step does, and it is the opposite of a rewrite.

1. Open the chapter and tell the chat what you want in plain words: "Bring in Mara, the new neighbor, during the dinner scene. She only watches and says one line." Or: "Move this scene from the kitchen to the harbor at night." It changes only the paragraphs that need it and leaves the rest of the chapter alone. 5 credits per instruction.

2. Keeping tabs: nothing lands without your OK. Each proposed edit shows up highlighted in the editor, and you accept or reject them one by one or all at once. "View Changes" puts the original and the new version side by side. Only Regenerate replaces a chapter's text, and you never have to use it.

3. A new character: add them on the Characters step first (free). The chat editor reads your character list and the chapter's outline, so it writes them in consistently. If they matter later, add them to those chapters' outlines too. The chat works one chapter at a time, so a change that runs through the whole book is one instruction per chapter.

4. One honest limit: there is no saved version history. Undo works while the tab is open, but once you accept a change and leave, the old text is gone. If you want a record, export a DOCX before a round of edits and compare it with a later export in Word (Review > Compare).

5. When you are done, the Book Editor tool (under Tools) reads the whole manuscript and returns an editorial letter plus a style sheet that catches continuity slips across chapters. Handy after you move a location or add someone. 7 credits per 1,000 words while it is in beta.

A saved change history is a good idea. If you want it, add it to our public roadmap and vote on it: https://aiwritebook.com/app/public-roadmap

I hope it helps!

Thank you it does help! And yes just making it easy to keep submitting the book as a collection of chapters in .md format would make diffing very easy

Founder

Mykyta_Founder_AIWriteBook

Glad it helped. To be straight with you: import takes one Word .docx per book, and exports are DOCX, EPUB and PDF, so no .md chapters in either direction today. Chapter version history is already on the roadmap to vote on, and per-chapter .md import and export would make a good idea of its own: https://aiwritebook.com/app/public-roadmap

Q: Are you planning to integrate the new Gemini 3.8 TTS for audiobooks? Huge cost advantage compared to ElevenLabs

Hello Mykyta and team!

Google has just released Gemini 3.8 Flash TTS and Flash-Lite TTS. These next-gen models are incredibly powerful, support line-by-line direction (emotions, whispering, laughter), and are dramatically cheaper than ElevenLabs (currently from $0.54 to $0.81 per audio hour). Would it be possible to integrate Gemini 3.8 TTS directly into AIWriteBook? Ideally, so it can be easily deducted from our regular monthly plan credits, instead of forcing us to connect an external API key. This would add immense value to the lifetime deals and make audiobook creation far more accessible. What do you think?

Founder Team

Mykyta_Founder_AIWriteBook

Sep 24, 2026

A: Hi,

Not today. The Audiobook Studio runs on ElevenLabs v3 only, and it already takes your regular plan credits: 1 credit per 12.5 characters, plus 20% when you cast several voices. A 75% launch discount runs until 6 October, so a 2,000-word chapter costs about 220 credits single-voice right now instead of about 880. Your own ElevenLabs key is an option from Tier 3, never a requirement.

The line-by-line direction you describe is there already: emotion tags steer delivery per line, and you can re-record one paragraph without paying for the rest of the chapter again.

On Gemini 3.8 Flash TTS: before we swap engines, it has to hold up over a whole book. The same voice has to sound the same in chapter 1 and chapter 30, and a dialogue exchange has to keep its rhythm. If it does, the price difference is a strong argument.

The closest open roadmap item is "Support third-party TTS providers with bring-your-own-key alongside ElevenLabs". Yours is different (plan credits, no key), so add it as its own idea or comment on that one, and vote: https://aiwritebook.com/app/public-roadmap

I hope it helps!

Q: Difference between Tier 3 and Tier 4

I know this question has been asked generally before, but is the specific, detailed difference between Tier 3 and 4 only the credit amounts and the Nanoreads support? Is there any other discrete difference?

How about between Tier 4 and the standard Pro plan? Is there anything available through the subscription Pro plan that isn't in Tier 4?

And I know you cannot predict the future, but is your vision to catch the eye of a bigger fish and sell, or is your vision to indefinitely develop this and your associate apps (i.e. Nanoreads) organically. This affects whether it makes more sense to subscribe vs LTD.

Founder Team

Mykyta_Founder_AIWriteBook

Sep 23, 2026

A: Hi gbmoscoe,

Subscription versus lifetime is a real decision, so here are the exact lines between the three.

Tier 3 vs Tier 4: two differences and nothing else. Tier 4 gives 5,000 credits a month instead of 2,500, and it includes publishing on NanoReads, our reading platform with iOS and Android apps (example: https://nanoreads.com/books/cancer\_wont\_break\_her). Everything else is identical on both: book translation, Audiobook Studio, visual books, series continuation, the public author page, the KDP research tools, DOCX export, the Format step for print-ready PDF and EPUB, and bring-your-own-key through OpenRouter, where any action that runs on your own key costs 1 credit.

Tier 4 vs the Pro subscription: Pro also gives 5,000 credits a month, and there is no Pro feature missing from Tier 4. It goes the other way, in fact: bring-your-own-key is not in Pro at all, only in Ultra and in Tiers 3 and 4. The deal terms link Tiers 2 to 4 to the Pro plan, so new Pro features reach Tier 4 as well. One caveat is written into those terms: access to future AI models may come at a discounted rate or as an add-on. Credits work the same way on both, they reset every month and do not roll over. The practical difference is flexibility: Pro is $50 a month or $360 a year and you can stop at any time, while the deal is a one-time purchase.

On the vision: nobody can promise what happens in ten years, but everything we do today goes into building AIWriteBook and NanoReads as one long-term product. NanoReads exists because we want books written here to have readers, and that is a long project. What we ship next is decided on the public roadmap, where anyone with a free account can vote and submit ideas: https://aiwritebook.com/app/public-roadmap

Current prices and credit costs: https://aiwritebook.com/en/pricing

I hope it helps!

Q: Can you add this feature (book signal)

Hi, I’m curious if you can add a feature to your app. I have tier 5, and I’m thinking of a feature called "Book Signal"—just a phrase I came up with, but you can name it anything. It would allow users to fully research book data and ideas that sell on Amazon, instead of writing blindly.

Founder Team

Artem_Founder_AIWriteBook

Sep 20, 2026

A: Hi Sunflow,

Book Signal is a good name for it, and the idea is close to something we already have half of, so let me be precise about which half.

What is in the app today, all of it under Tools:

1. Niche Finder (15 credits). Give it a seed topic and pick a marketplace: Amazon US, UK, DE, FR, IT, ES, JP, CA or AU. It pulls live Amazon autocomplete for your term and its related terms, then scores each niche for demand, competition and profitability, with sub-niches, content angles and a list of areas where demand exists but competition does not.

https://aiwritebook.com/en/tool/niche-finder

2. Competition Analyzer (15 credits). Same marketplace choice. Point it at a keyword you are considering and it profiles the books you would be publishing against, so you find out a niche is crowded before you write it instead of after.

https://aiwritebook.com/en/tool/competition-analyzer

3. KDP Keyword Research (15 credits). Search volume and competition scores per keyword, a check against KDP's restricted words, plus category and related-term suggestions. This one is fixed to Amazon.com; the marketplace selector exists in the two tools above but not yet in this one.

https://aiwritebook.com/en/tool/kdp-keyword-research

4. Trend Spotter (10 credits) for timing, Category Finder (10 credits) for the BISAC and browse categories, and a Royalty Calculator that is free.

A word on the numbers before you lean on them. Amazon autocomplete is real data and it is what the first three read. Everything built on top of it is the model's estimate: estimated monthly searches, average price, average monthly earnings, competitor counts. We do not read Best Seller Rank, we do not scrape sales, and we do not follow a title over time. So rank your candidates against each other with those reports, then check the two or three you like on Amazon itself, which costs nothing: autocomplete, the Best Sellers list for the category, and how recent the dates are on the top titles.

Which puts your request exactly on the layer underneath what we have: real sales signal instead of estimated signal. I am not going to promise that here. It is a proper decision rather than a quick addition, because it means paid data or scraping that we do not do today.

The place to put it is our public roadmap, which is where we count demand and pick what gets built next: https://aiwritebook.com/app/public-roadmap

Post it as Book Signal and describe what you would want on the screen. Two things already open there are worth a look if you would rather add weight to one of them: an end-to-end guided workflow from market research through to publication, and a catalog dashboard with rank, reviews and sales per book.

One practical note: none of these tools are tied to a tier. They cost credits and nothing else, so whatever you hold, they are all open to you.

I hope it helps!

Artem

Thanks! I guess I need to explore your app more 😀. Great job on today's update features. I remember wanting to chat with the system about getting my cover design to meet Amazon's recommendations. Now, with the update, that's no longer a problem. Good job!

Founder

Mykyta_Founder_AIWriteBook

Thanks Sunflow. Close - the Format step checks the cover rather than chats about it: it flags low DPI, builds the wrap spine and barcode zone from your page count, and warns when the trim is outside KDP limits, all before you upload. Reworking the art itself still happens in the cover editor.

I hope it helps!

Q: Can I import my audio mp3 manuscript?

I do a lot of dictation for my books.

Can I import my audio manuscripts to use within AIWriteBook?

Mark

Founder Team

Artem_Founder_AIWriteBook

Sep 13, 2026

A: Hi Mark,

No, not today. Import takes .docx, .doc, .pdf, .epub, .rtf, .odt, .txt and .md, and there is no transcription step anywhere in the app, so an audio file has nothing to attach to. Audio only runs the other direction: Audiobook Studio narrates chapters you already have.

Since you dictate, the working route is to transcribe first and import the text. Whatever you already dictate into does this for you, phone dictation, macOS or Windows voice typing, or any transcription tool, and it hands you a .docx or .txt. That file is what you upload.

Two things to know before you do. Only DOCX carries formatting and embedded images through, so a .txt transcript imports fine but lands as unstyled text. And the main importer asks how many chapters are in the file, then goes looking for the breaks, which works best when each chapter starts with a heading like "Chapter 1: The Beginning". A raw dictation transcript will not have those, so add them before uploading. If your number and our count disagree, the import stops and shows you both instead of guessing, and it handles up to 50 chapters at a time.

If you would rather not hand-label anything, the Book Editor has a second DOCX importer that works differently: https://aiwritebook.com/app/tool/book-editor. It reads Word's own heading styles and relative font sizes rather than the wording, and where it does fall back to text it matches Chapter, Part, Prologue, Epilogue, Introduction, Conclusion and Appendix, plus numbered and roman numeral headings. So a section titled Introduction is picked up there without the word Chapter appearing anywhere.

Costs so you can plan. Chapter text is 10 credits per chapter, or 13 if you keep DOCX formatting and images. Outline is 3 per chapter. Details and characters cost nothing. An account that has not bought anything yet gets its first book import free.

Audio import is a reasonable ask, and I would rather it be voted on than sit in my inbox. Our roadmap board is open to everyone and it is what we pick the next build from: https://aiwritebook.com/app/public-roadmap

I hope it helps!

Artem

Correction to the answer above: import now takes one Word .docx only. The other formats listed there get a convert prompt instead of importing, so a .txt transcript no longer works - save it as .docx first (File -> Download -> Microsoft Word). The rest stands: transcribe, add Heading 1 chapter titles, then upload. Sorry for the stale list.

I hope it helps!

Very promising tool for creating consistent, readable books

I tested AIWriteBook with a short book project using 8 chapters. The result was around 20 pages of text in total. For me, this is currently its main weak point: each “chapter” ends up being roughly 1,200–2,000 words, or about two pages long.

That is not quite what I am used to when thinking about a traditional book. If you wanted to create a proper 80,000-word novel at this pace, you would need around 53 chapters. Personally, I am used to books where a single chapter can be 20 pages or more—not just two pages.

I think this may be a general limitation of AI-generated long-form writing rather than something unique to AIWriteBook. A possible solution could be adding sub-chapters, scenes, or expandable chapter sections, so users can build longer and more substantial chapters while maintaining story continuity.

Another weak point, in my opinion, is the export workflow. The process seems focused on making the book author-page or Kindle-ready, which is useful for users who want to publish immediately. However, what if I simply want to export the manuscript as a DOCX file so I can edit it properly offline first? For many writers, the next step after generating a draft is detailed manual editing in Word, Google Docs, Scrivener, or another writing program. Having a clear and easy DOCX export option available earlier in the process, rather than only at the very end, would make the workflow much more flexible.

That said, there are several things AIWriteBook does very well.

What impressed me

- Story consistency: For an 8-chapter test, the story stayed surprisingly coherent. The plot, characters, and overall direction remained consistent. I am curious to see whether this consistency holds up across 60+ chapters, but the early test was genuinely promising.

- Readable writing and good flow: The text is easy to read and flows naturally. Other AI writing tools often lose track of the story and end up damaging the pacing or writing sections that feel disconnected. AIWriteBook handled this much better in my test.

- “Voice of Author” feature: This is probably one of the strongest features. It really does a convincing job of writing in the author’s voice. Other tools have made similar promises, but I have not seen them deliver at this level. This feature is very well made and genuinely impressive.

- Credit system: The credit model is fair for book writing. Writing itself does not consume a huge number of credits; most of the cost comes from images and audio, which is understandable.

Things to consider

Audiobook generation can become expensive. For my approximately 20-page test book, it would take around 1,500 credits for audio. For a 200-page book, that could reach approximately 15,000 credits.

At the current pricing, that could mean roughly 8 one-time 2,000-credit packs—around $400. That gets expensive very quickly, although it may still be worthwhile if the finished book and narration are high quality.

It could be useful if audiobook creation could be split over time—for example, creating different parts across three months while using the highest tier. I also noticed there is a BYOK option for ElevenLabs. I did not test it, but it may offer more flexible or affordable audio options.

Overall

If you are willing to properly work with the tool—edit the outline, improve the structure, define characters carefully, and guide their development—it is a very enjoyable and capable platform.

There is plenty of room for improvement, especially around chapter length and options for building longer books. But the core idea and execution are strong. The tool already handles its main purpose very well, and expanding its long-form capabilities would make it even better.

My rating: 4.5/5, rounded up to 5 stars. This rating sums up the fact that, for me, this is probably the best tool I've tried so far on the AI book-writing niche. I've tried 5 of them.

This is the most useful review we have had, so let me pay it back with numbers,

including one place where the app misled you.

Chapter length. 1,200 to 2,000 words is not the ceiling, it is what the outline AI

filled in for you. Every chapter card on the Outline step has a Target Words field,

and the same field sits in the Story Bible rail of the writing screen. The range is

100 to 5,000 words on fiction, 200 to 5,000 on non-fiction, and the writer is held

to within about 10 percent of whatever you type. Our published print sample runs

284 words to a 6x9 page, so a 5,000-word chapter is 17 to 18 pages, not two. Your

80,000-word novel is 16 chapters at 5,000, not 53. The sample is downloadable if

you want to measure it yourself:

https://aiwritebook.com/samples/echoes-of-the-silicon-soul-6x9-print.pdf

The economics run your way too - a chapter costs the same credits at 5,000 words as

at 500, so long chapters are the cheaper way to reach a page count.

Expanding what you already have. Open the chapter and use the AI Editor panel on

the right, 5 credits a request: "expand the arrival scene, add 400 words of

description before the dialogue". It inserts new paragraphs as highlighted

suggestions you accept or reject one by one. If you would rather have the whole

thing rewritten longer, raise Target Words in the Story Bible rail and hit

Regenerate Chapter, at the normal 15/20/30 credits. That one replaces the chapter,

so do it before hand edits you care about.

Scenes and sub-chapters we do not have. Someone has already put it on our roadmap

in almost your words, and it is open for votes right now at

https://aiwritebook.com/app/public-roadmap - your vote on that one is worth more to

me than my opinion of it.

DOCX. Half right. DOCX export does not wait for the book to be finished and it is not tied to publishing - it sits on the Export step and works with a partial draft. The one condition is that the Export step opens once the book has a cover, so generate or upload one first, then DOCX is available right away, however much of the manuscript exists.

Audiobook. The price is 1 credit per 12.5 characters of narration, plus 20 percent

when the book is cast with multiple voices, and a 75 percent launch discount is

running until 6 October. Your 1,500 credits works out to roughly 62,500 characters,

about 11,000 words - so it was your page estimate that was low, not the quote. A

real 200-page book is around 57,000 words, which comes to roughly 7,800 credits

multi-voice at today's rate, closer to 6,500 single-voice. Worth knowing the

discount is temporary: after 6 October those numbers are four times higher.

Your idea about splitting it over months is already how it behaves. Credits come

out per chapter as each one renders, never upfront for the whole book, so you can

narrate three chapters this month and the rest after your Tier 3 credits refresh.

And yes on ElevenLabs. Tier 3 includes bring-your-own-key, and audiobook is one of

the actions it covers - connect your own ElevenLabs key in settings and narration

costs 1 credit on our side while ElevenLabs bills you directly for the audio. For a

200-page book that is the difference between thousands of credits and almost none.

Thank you for the Voice of Author line especially. Tell me how the consistency

holds if you take one past 60 chapters - that is the test I want to see.

I hope it helps!

A Great Way to Keep a Nonfiction Book Under Control

I am currently using the Tier 3 plan to create a nonfiction book, and after planning the project and completing the first two chapters, my experience with AIWriteBook has been positive.

What I like most is the feeling of having the entire book under control. The synopsis, target audience, tone, outline, chapter order, and word-count goals are all kept together in one project. I can easily see what has been completed, what remains to be written, and how each chapter fits into the overall structure. For me, this is much easier than managing a complete nonfiction book through separate conversations with ChatGPT or Claude.

The ability to choose between different AI models is also useful. Claude produces more natural narrative prose, while Gemini works well for explanatory and structured content. Tier 3 provides a generous credit allowance, giving me enough room to revise or regenerate chapters when necessary.

The process is not fully automatic. Nonfiction content still requires careful fact-checking and human editing. I have encountered some inaccurate details, repeated passages after AI revisions, confusing tracked changes, and one chapter generation that stopped before completion.

Overall, AIWriteBook is a very useful workspace for planning, organizing, and drafting a nonfiction book. Its greatest advantage is helping me keep the whole manuscript under control while AI assists with the writing. Based on my experience so far, I would give it 5 stars**.

Hi gestodedios,

Two chapters into a nonfiction book is where you actually find out whether something is a workspace or a slot machine, so thank you for reviewing it from there rather than after one prompt. Your read on the models matches ours: Claude is better in narrative passages, Gemini is steadier on explanatory and structured material.

On the four problems you hit.

Inaccurate details. Nothing in the writing pipeline searches or browses the web, so a chapter is the model writing from your brief plus what it already knows, and for nonfiction that is where wrong dates and invented specifics come from. The way to bind it down is the Details step: upload reference files (first one free, 10 credits after that, up to 10 files) and switch the citations toggle on. That routes chapter writing to Claude at 30 credits per chapter, and the AI places numbered markers inline with an APA 7 reference list per chapter, carried into the EPUB, PDF and DOCX. Every source in it is one you handed over, which is the point: it cannot cite something you did not give it.

Repeated passages after revisions. The AI editor reads the whole chapter rather than only the part you asked about, so a narrow request comes back with broader proposals more often than it should. That one is on us and the precision is not where we want it. What helps today is pasting the exact sentence into the request in quotes and asking for the single change. It narrows what the model touches.

Tracked changes. Every proposed change has a green check and a red X on it, and the bar at the top has Accept all, Reject all, and a Next change button that walks you through them one at a time. Reject all puts the chapter back exactly as it was, so trying an edit costs you nothing. One thing that is not signposted anywhere: clearing the chat also throws away any changes still pending, so resolve the diff before you clear.

The chapter that stopped early. Credits only come off after a chapter is saved, so a run that dies before that costs nothing. If it saved short and still charged you, that is the case I want to see. Send me the book title and chapter number, or write from the support chat in the app, and I will pull the server log for that generation.

Editor precision is the item I would most like ranked by people actually writing books, so if you want to push it up the list: https://aiwritebook.com/app/public-roadmap

I hope it helps!

I Spent Years Talking About My Personal Finance Book. Aiwritebook Got It on Amazon

For years I gave the same advice at kitchen tables and after work — how to get out of debt, how to build a first emergency fund, how to stop feeling ashamed of money. Everyone told me to write the book. I agreed with them every time and then did nothing, because I had no idea how to turn a hundred scattered conversations into chapters that actually built on each other.

Aiwritebook is what finally broke that loop. It didn't hand me a book; it helped me interrogate my own material. What does the reader already know by chapter four? Which story earns its place and which one am I keeping out of sentiment? Within days I had a structure that made sense, and the writing stopped feeling like guessing. The vague ambition I'd carried for years turned into a table of contents I could work through one section at a time.

As I write this, my book is live on Amazon. Not in a drawer, not in a folder called *ideas* — published, with my name on it, being read by people I've never met.

**Aiwritebook gave me the clarity to see the book I already had inside me, and the structure to finally finish it.**

Also ran into some issues not from Arwritebook but from Amazon when I was publishing my book but their support chat helped solved my issue and walked me through it and got it fixed.

Congratulations, Sunflow. Years of kitchen-table advice becoming a book that strangers are now reading is the outcome that matters, and you did the hard part of it.

"It helped me interrogate my own material" is the best description of the outline step I have read. Which story earns its place is exactly the question it is built to make you answer before you write a word.

One small thing, if you have not done it: paste the Amazon link into Buy links on the book's Publish step. Then readers who find you through your author page can find the book too.

I hope it helps!

Turned my biggest hangup (the cover!) into my favorite surprise, and gave my audience a real audiobook option

I came to AIWriteBook with one goal: turn a full draft I'd already written into an audiobook. I uploaded the manuscript as is, figuring that was the whole test. What I didn't expect was to end up poking around the writing tools too, and being genuinely pleased with what I found. It doesn't try to rewrite everything or bury you in suggestions. It stayed pretty quiet on my already finished draft, but what it did flag was actually useful, not just noise for the sake of having something to say.

The real shock for me was the cover design studio. I'm a designer by trade, so I was fully prepared to be unimpressed. I only tried it because I'd been stuck on my own cover for longer than I want to admit. The imagery it came up with was spot on, exactly the mood and composition I'd been trying to land on myself. I'll tweak the fonts to match my own style before I use it, but as a starting point it saved me hours of trial and error.

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.

The one hiccup I ran into was downloading the finished audiobook as a single file. It wouldn't let me pull the whole thing at once, and that one is still being worked out. What made it a non issue for me in the meantime is that I could still download it chapter by chapter, which actually worked out well since one of my reviewers needed to listen to the book rather than read it, and chapter files were easy for her to work through. I also want to give credit where it's due: the owner personally jumped in to help me troubleshoot, and is still actively working the problem rather than brushing it off. That kind of hands on attention is rare, especially from the person actually running the company.

Between a genuinely one click path to a full audiobook, a cover design tool that held its own against an actual designer, and writing help that knew when to stay out of the way, AIWriteBook delivered a lot more than I expected. Highly recommend.

Skye, thank you for this. The line I keep rereading is that you came in as a designer fully prepared to be unimpressed by the cover studio. That is the hardest audience it has.

One pointer, since you said you will tweak the fonts: once you have your version, upload it back on the Metadata step. Then the cover that goes into your exports is yours, not ours.

And you are right about the merged audiobook file. It is not the size of your book, it is a bug on our side, and it is still open. Chapter by chapter keeps working while I sort it out, and I will follow up when it is fixed.

I hope it helps!

The outline builder is what sold me

I came in skeptical. I've tested a lot of AI writing tools and most of them fall apart at the structure stage. You get a table of contents that reads like a Wikipedia stub, and then you're doing the actual thinking yourself anyway.

That's not what happened here. I ran a couple of book concepts through the outline builder and the structures came back specific enough that I could see the finished book. It knew the difference between a chapter that carries an argument forward and a chapter that just fills space. The output quality genuinely surprised me, and structure is the part I usually dread most.

Being upfront about scope: I've spent a handful of sessions with it so far, mostly on planning and outlines. I haven't taken a manuscript all the way through to KDP export yet, so I can't speak to formatting, covers, or the audiobook side. If those are your primary reason for buying, read the reviews here that cover them in detail..

What I can say is that the foundation is right. Outlining is where these tools usually break, and this one doesn't. At the deal price that's enough for me. I'll come back and update this once I've published something with it.

Hi Hermannn,

The line I keep re-reading is the one about it knowing the difference between a chapter that carries an argument forward and a chapter that just fills space. That is the exact failure mode the outline step was built around, and almost nobody names it out loud. People feel that an outline is thin and move on without being able to say why. So thank you for saying why.

That part is not the model being lucky, for what it is worth. The outline step never asks for a table of contents. It first proposes three whole-book structures where every part has to state what job it does and over which chapters, then a chapter template where every section has to state its own purpose, and the chapter outlines are written against that template. A chapter that exists only to fill space has nothing to put in those fields, so it usually does not survive the step.

On your scope note: you spent your sessions on planning and outlines, so that is what you speak to. That is the right way to do it, and I am glad the foundation held up. When you do take a manuscript all the way through, I would like to hear where it holds and where it does not, the export side especially.

Cheers,

Artem
