Manuscript AI

Youbooks is an AI non-fiction book generator that drafts manuscripts of up to roughly 300,000 words grounded in your own research sources and a custom-trained "Human model" of your writing voice. It emphasizes a slower, multi-step agentic workflow — over a thousand steps per book — instead of quick one-shot generation.
