Youbooks
Youbooks is a long-form non-fiction book generator that turns prompts and optional source documents into publish-ready drafts. You describe the topic, attach PDFs, DOCX files, or notes when you want chapters grounded in your research, and export finished manuscripts in DOCX, EPUB, Markdown, or RTF.
The platform runs a multi-stage workflow across thousands of steps, using agentic brainstorming with models including ChatGPT, Claude, Gemini, and Llama before writing and editing chapters. You can set structure and word count targets up to 300K words, approve the table of contents before drafting starts, and optionally train a Human Model on 20K to 200K words of your writing so the voice matches your own.
Youbooks is built for practical non-fiction such as how-to guides, business books, and educational explainers. Fiction projects are rejected and refunded. Premium books typically take days to complete rather than minutes, with coherence checks and editing levels to tighten longer manuscripts.

Is the content generated by Youbooks plagiarism-free?
Yes. Youbooks generates original non-fiction drafts from your prompt and optional sources. You retain full rights to the content and any trained Human Model voice you create.
Can Youbooks create fiction books?
No. Youbooks supports non-fiction only. Fiction and erotica projects are rejected and refunded.
Can I use Youbooks for commercial purposes?
Yes. Youbooks is designed for commercial publishing workflows. You keep ownership of generated drafts and can export them for KDP, Ingram, or other publishing channels after your own final polish.
Can I edit the content generated by Youbooks?
Yes. Delivered books are meant as drafts for final editing. You can export to Markdown or DOCX and revise before publishing.
How long does it take to create my book?
Premium books typically take days, not minutes. Youbooks runs thousands of research, brainstorming, writing, and editing steps per project. The homepage estimator commonly shows around two days for a typical book configuration.
What formats will I receive my book in?
Delivered books can be downloaded as DOCX, EPUB, Markdown, and RTF. Outputs are unbranded so you can apply your own layout before publishing.
How much does it cost to use Youbooks?
Youbooks uses a credit system. Monthly subscriptions start at ?9.97 for the Fan plan (200K credits), ?24.97 for Pro (500K credits), and ?199.97 for Enterprise (700K credits). Credit top-ups start at ?5 for 50K credits, and each book project includes a 9,000-credit base fee.
How does Youbooks differ from other AI book writing services?
Youbooks focuses on long, cohesive non-fiction rather than quick article-style drafts. It runs agentic brainstorming across multiple frontier models, optional Human Model voice training, TOC approval, source grounding, and multi-day refinement before delivery.
Is there a free trial?
Youbooks does not list a free subscription tier on its pricing page. You can explore the book builder on the homepage, but paid credits or a subscription are required to generate and download full manuscripts.
