It makes writing very easy to write a book.
It makes writing very easy. I use it mainly for scaffolding and it helps me to develop my manuscript fast yet still with quality. I can highly recommend AIWriteBook.com! I already have 5 books in the making and the first month is not even over!

Good product - one of the best for fiction
I had this before the APP sumo deal, and so lifetime is wonderful! The BYOK is a real help and should certainly positively impact edits. It's AI so don't expect miracles; it still creates errors in edits. Can it create good fiction content - yes, does it need a human to direct it? Absolutely. It gets better all the time, and the team is super helpful.

Oct 20, 2026Hi,
Thank you, and welcome to lifetime. Good to see you made the move after your BYOK question.
You're right that it still needs a human directing it, and that's how we build it: you decide, the AI drafts and suggests. On the edit errors, a few things that cut down on repeat corrections in the chat editor:
1. Give it one passage at a time instead of the whole chapter.
2. Quote the exact...

Good, not perfect at following instructions
Overall, I like this tool and it's already saving me a lot of time. I already had a good start on my nonfiction book and gave it a lot of material to work with. The outline it generated wasn't quite what I had in mind, but it's not bad. Also, despite my instructions to use my exact words as much as possible and not make things up (my book is nonfiction/memoir), it is still inventing characters and events that I then have to remove. I imagine this tool might work best for someone starting from scratch rather than one as far along in its development as mine was, and I imagine it would be a fantastic tool for fiction writers. For my next book, I will start from scratch and see what happens! Still, this tool is useful enough that even though I need to do a lot of editing, it did a great job of organizing and writing. I'm happy with the purchase.

Oct 20, 2026Hi,
Thank you for the honest review, and for sticking with it through the editing.
You're right that it still invented people and events even with a clear "don't make things up" rule. On a non-fiction book, part of that comes from the setup: Details picks like "Case studies" and "Real-world examples", and chapter fields like real-life cases, ask the AI to bring that material into every chapter....

Finally Took It for a Real Test Drive... And I'm Impressed!
I’ll admit it... I’ve bought nearly 400 deals over the years here on Appsumo and I don’t leave reviews often. And yes, true to form, I let this one sit for a bit before I finally cracked it open. But when I logged in and realized my monthly credits were about to refresh and I hadn't even used any of them, I decided I may as well use some of those credits to take it for a spin.
So I gave it two real tests.
Test #1: I gave it an idea I wasn’t committed to, just to see what it would do. It built a full 12-chapter book. Good structure, very readable... but when you don’t give it much to work with, it fills the gaps with its own made-up examples. Lesson learned.
Test #2: I gave it one of my own proprietary frameworks, my own definitions and examples. WHOA... What a difference! In one afternoon I had a clean nine-chapter book, an Editorial Review of the whole manuscript, a cover, and a 2.5-hour audiobook that I uploaded to a Past Appsumo Deal - Soundwise - so I can listen to it via an App on my Phone through my Bluetooth as I'm driving around in my Car.
What impressed me most:
* There are places EVERYWHERE to give it instructions. Book description, chapter notes (up to 40,000 characters), reference files, and per-chapter AI instructions. The more of YOUR material you feed it, the more it sounds like your book instead of everybody’s book.
* You pick the AI model chapter by chapter (I've tested Gemini & Claude and as you likely already know Claude it better overall for writing as represented by the 30 credits per chapter instead of 15 credits per chapter for Gemini) so I've been using Claude for each of my Chapters.
* The Editorial Review is legit. It caught repetition across chapters that would’ve taken me hours to find myself.
* The founder actually answers questions. I posted one and had a detailed, honest reply the next morning.
A few tips from my testing:
I've only tested the Non-Fiction Book type so these tips will be based on that...
* Feed it your own content and examples if you have them. Garbage in, garbage out still applies.
* Read the Line Edits before accepting them. Some suggestions made my plain-talk style a bit too academic for my taste... In fact, while the Editorial Review provides to usable data, I found myself pretty much skipping the Line Editor (at least for my second book) even though once I get even better at using it, maybe I will find the Line Editor more useful for me.
* The audiobook feature is impressive, but it uses a big chunk of credits, so good thing I have Tier 4 - because if you plan on using the Audiobook feature much, you'll require reasonable credits for that. My 9 Chapter approx 22K word book cost about 2,500 credits (or around that amount). The quality of the AudioBook Voice I selected turned out really good though.
Bottom line... If you have content, frameworks, courses, or ideas sitting around that deserve to become books, this tool will get you from “someday” to “done” faster than anything I’ve tried.
In fact, I'm in the Middle of Developing a Portable Playbook for my Book Creation Workflow which will now involve AiWriteBook.
May the Force Stay with this One!

Oct 19, 2026Thank you for finally cracking it open, and for writing up both tests so honestly. Test #1 vs Test #2 is the lesson I'd want every new user to read: give it your own frameworks and examples and you get your book. Give it little and it fills the gaps itself.
Your numbers check out. Claude is 30 credits a chapter and Gemini is 15. Narration is 1 credit per 50 characters, so a 22K-word book comes to...

Finally started the book I’d been putting off for years
I’ve wanted to write a book for as long as I can remember, but it always felt too daunting to even start. AIWriteBook changed that. I’m now two chapters into the first book of a sci-fi trilogy, and I’m genuinely enjoying it.
The planning side is brilliant for a first-timer. Setting up the book description, character sheets and a chapter-by-chapter outline (locations, plot events, hooks and twists, character interactions) gave me a clear map, so I’m never staring at a blank page wondering what happens next. I went for Tier 3 for the series support, and having everything for a trilogy in one place has been worth it.
What’s surprised me most is the advice. I’m writing the chapters myself, and the style checker picks out things I’d never have noticed as a brand new writer: over-explaining, clichés, repeating myself. It doesn’t just flag them, it explains why it’s a problem, and that’s taught me more about writing than I’d have picked up on my own. You can also re-check a chapter after making changes, which is handy.
If you’ve always had a book in you but didn’t know where to start, this is a great way in. Highly recommended.

Oct 19, 2026Congratulations on starting the trilogy. Two chapters into book one after years of putting it off is a real start.
Thank you for describing how you use it. Writing the chapters yourself and letting the style checker explain the why is how we hoped people would learn with it. Re-checking after your edits is the right habit.
One tip for later, since you're on Tier 3: when you start book two, mark...
