YouBooks Writes the Manuscript. AIWriteBook Publishes the Book.
YouBooks is a non-fiction manuscript generator that takes 2+ days and meters every word as a credit. AIWriteBook drafts a complete 20-chapter book in roughly 30 minutes โ fiction or non-fiction โ and bundles the cover, audiobook, proofread, and KDP-ready export.
No credit card required
Why YouBooks Stops Short of a Finished Book
A long manuscript is not a published book. Here's where the gap shows up.
Two Days to See a First Draft
YouBooks describes itself as the slowest book generator on purpose โ typical projects take 2+ days, longer ones up to 4 days. AIWriteBook drafts a 20-chapter book in roughly 30 minutes, so you can read, edit, and decide what to keep the same afternoon.
Credit Anxiety on Every Decision
YouBooks charges roughly 1.1 words per credit plus a 9,000-credit flat fee per project, with extra spend for source digestion and human-model training. Credits reset monthly and unused credits don't roll over. AIWriteBook is a flat plan โ write, regenerate, polish without watching a meter.
Non-Fiction Only, Manuscript Only
YouBooks currently supports non-fiction only and exports DOCX, EPUB, Markdown, or RTF โ no cover, no audiobook, no proofreading pass, no KDP-ready bundle. AIWriteBook covers every genre and ships the full publishing workflow in one place.
What's Bundled with AIWriteBook (and Not with YouBooks)
A finished book needs more than a Word document.
KDP-Spec Cover Designer
1600ร2560 covers built for Amazon KDP, generated from your premise. Included on every paid plan.
20-Voice Audiobook
Twenty verified AI voices turn your manuscript into a listen-ready audiobook. No separate ACX subscription.
Discrete Proofreading Pass
A dedicated AI proofreading stage runs across the finished book โ not stitched into drafting, so you can see exactly what changed.

What Real Authors Say About AIWriteBook
Authors who wanted a finished book, not a long manuscript
"I have had the best experience with AIWriteBook after trying several other book writing apps. This one is by far my favorite. I love how I can upload my rough draft and it can be edited, expanded, outlined, detailed and publish ready."
"I have been using Gemini and Claude separately to write my books, this does it all in one place and the chapters actually connect to each other. Much better workflow."
