Co-Author a Book with Grok: From a One Liner to a Book in 100 Hours

In this groundbreaking session from the Artificial Unintelligence Conference 2025, Lars Rönnbäck demonstrates how generative AI tools like Grok can transform the creative process — helping writers go from a single idea to a fully developed book in under 100 hours.

Lars shares his personal workflow for using AI as a true co-author, starting with a concise “one-liner” concept that serves as the creative compass for the entire project. Through iterative prompting, structured feedback, and human refinement, he shows how authors can maintain voice, coherence, and depth while leveraging AI’s speed and scale.

This talk explores not just the technical process, but the philosophy of collaboration — how human intent and machine output can blend into something neither could produce alone.

Key themes include:

How to frame a one-liner that drives narrative consistency

Using AI to accelerate structure, research, and drafting

Maintaining authorial voice in AI-assisted writing

Editorial curation as the heart of co-authorship

The future of creative collaboration and AI publishing
