Be honest: is there a half-finished book sitting in a Word file somewhere on your laptop? Chapter 4, last edited two years ago?
You’re in good company. Writing a book isn’t one job, it’s ten: outlining, drafting, editing, the cover, formatting, Amazon categories, marketing… AIWriteBook tries to put all ten in one place. It learns your voice, helps write the missing chapters, then gets you to a KDP-ready file, cover and launch kit.
The AIWriteBook lifetime deal is on AppSumo from $79. We read all 221 reviews and compared every tier with AIWriteBook’s own pricing. One thing first: AppSumo marks 87 of those reviews as incentivized (the reviewer got something, like bonus credits, for writing them), so we paid extra attention to the critical ones.

What AIWriteBook actually does for you
1. Writes chapters in your voice, and you approve every change
Import your draft or start from an idea. You build characters, an outline and a writing-style profile, then AIWriteBook writes chapters. The AI editor suggests changes you can accept or reject one by one. Longer chapters don’t cost more credits than short ones, which reviewers say makes long books more economical.
2. Expert Book and real research for nonfiction
Made-up facts were the biggest complaint, so the team just shipped two fixes. Internet research reads about 20 real web pages before writing and cites them, so you can check every claim. Expert Book is for coaches and consultants: you upload your PDFs, slides, talks or call recordings, it interviews you about the gaps, and it writes only from your material. An editor feature also reads the whole manuscript and catches continuity slips like a character’s name changing in chapter 9.
3. Cover, KDP files and launch kit
It designs covers sized to your spine, exports EPUB and print-ready PDFs, suggests Amazon categories and keywords from live data, and builds a launch kit with graphics, social posts and emails. A Chrome extension even fills in your KDP listing.
4. Audiobooks, translations, series and picture books
Higher tiers add an audiobook studio, translation into 37 languages, series support that remembers book 1, and visual books (children’s picture books, coloring books, comics) where the main character looks the same on every page.
The good stuff (what buyers love)
- One complete workflow. The most common praise is that it goes from idea to KDP-ready files without juggling five tools.
- It can sound like you. Several buyers said chapters came out close to their own style when they gave it their own writing samples.
- Great for personal projects. One buyer is using it to turn an 83-year-old relative’s notes into a biography. Another finally finished a children’s story they’d had in their head for years.
- Choose your AI model. On Tier 3+, you can bring your own OpenRouter key and use Claude, GPT, Gemini and 100+ models. One reviewer found Claude better for stories and Gemini for structured nonfiction.
- A founder who listens. The founder replies to every question himself, and the latest update was built straight from reviews.
The not-so-good stuff (read this before you buy)
- Nonfiction facts need checking. A buyer who wrote three golf and travel books found too many factual errors to continue. The new research feature should help, but always fact-check.
- Repetitive, “AI-sounding” text. More than one reviewer mentioned repeated phrases. One said the visual book tool rewrote their own manuscript into generic prose and dropped characters.
- Credits go fast. Almost every action costs credits. One buyer used 500+ credits for a book of about 90 pages and said 1,000 credits a month is the real minimum for serious work.
- Glitches and a busy interface. Some reviewers found it slow or cluttered, and one lost front and back matter and images when importing a Word file.
- NSFW support was unreliable for one buyer, who said the AI often refused even when the option was enabled.
- A very young company. AIWriteBook was founded at the end of 2025, and every one of its AppSumo reviews is from 2026.
Is the AIWriteBook lifetime deal worth it? Let’s do the math
Here’s AIWriteBook’s official pricing (yearly billing) next to the AppSumo tiers. By AIWriteBook’s own estimate, 1,000 credits is about 200 pages.
| Plan | Credits / month | Key extras | Price |
|---|---|---|---|
| Plus (direct) | 1,000 | Writing, covers, KDP tools | $12/month ($144/yr) |
| Pro (direct) | 5,000 | + audiobook, translation, series, visual books | $30/month ($360/yr) |
| AppSumo Tier 1 | 500 | Writing, covers, KDP tools | $79 once |
| AppSumo Tier 2 | 1,000 | + audiobook, author page | $159 once |
| AppSumo Tier 3 | 2,500 | + series, visual books, translation, BYOK | $319 once |
| AppSumo Tier 4 | 5,000 | + NanoReads distribution | $519 once |
Tier 1 has half the credits of the Plus plan, so it’s best for slowly finishing one book. Tier 2 is the best value: it matches Plus credits, adds the audiobook studio and author page, and pays for itself in just over a year. Pick Tier 3 only if you need series, picture books, translation or your own AI models. Note that unlocking an Expert Book costs 2,500 credits in one go, so on Tier 1 or 2 you’d need to save up or buy extra credits.
Small print in the AIWriteBook lifetime deal terms: activate within 60 days, and future AI models may need an add-on or come at a discount. You can also buy extra credits that stack on top of your AppSumo plan.
Should you grab the AIWriteBook lifetime deal this Black Friday?
Yes, if you…
- have expertise or notes and want to turn them into a book
- self-publish on Amazon KDP and want covers, formatting and keywords in one place
- want to make children’s or picture books with consistent characters (Tier 3+)
- are happy to edit and fact-check what the AI writes
Skip it if you…
- want a “push one button, sell a book” machine
- write fact-heavy nonfiction and won’t check every claim
- prefer a minimal, distraction-free writing app
- plan to write a lot on Tier 1’s 500 monthly credits
Quick tip: Amazon KDP asks you to disclose AI-generated content when you publish, so keep that in mind if AI writes large parts of your book. Looking for shorter-form AI writing? See our Okaaaay AI writer review and our BlogAssistant review for blog content.
My honest take
AIWriteBook is one of the most complete book tools on AppSumo right now: writing, editing, covers, KDP files, audiobooks and a launch kit under one roof. It works best as a co-writer for people who already have something to say, not as a book factory.
Start with the free plan to test it on your own pages. If the voice matching works for you, Tier 2 is the sweet spot of the AIWriteBook lifetime deal. Then use your first two weeks to write one real chapter, fact-check it, and see how many credits it actually takes.

AIWriteBook estimates about 200 pages per 1,000 credits, so roughly 100 pages a month on Tier 1. Editing, covers and research use credits too.

It used to, and reviewers complained. The new internet research and Expert Book features write from real sources or your own material, but you should still fact-check.

Yes. AppSumo gives you 60 days to request a refund on the AIWriteBook deal.
