From an author who hated AI 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:

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.

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.

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.
