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. …
Read the full review on AppSumoMy overall experience is that it's a high‑quality product and I'm happy with my purchase. I would highly recommend it to anyone getting into writing or looking to refine a manuscript before it goes to print. …

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.

… My use case is strictly limited to travel non-fiction and I tested a few short stories with the Book Editor analysis. It’s brilliantly insightful and accurate; not dozy, vague suggestions like fix transition or blah-blah but deep actionable examples like an experienced human editor! …

… I am not using it for the whole write-a-book-from-scratch thing, but considering how much organization a technical non-fiction book can contain, it is helping me a lot, without losing my voice and tone. …

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. …
