Major US publishers are quietly using LLMs in editorial and marketing workflows

Why it matters for readers: It explains that big publishers are quietly using popular AI models for routine work, and that this has caused internal conflict.
- HarperCollins, Simon & Schuster, and Hachette have been incorporating LLMs into publishing processes without public disclosure or author consent.1
- Publishers are using models including Claude and ChatGPT to write emails to agents, produce publicity and back-cover copy, design cover art, and generate marketing materials.1
- HarperCollins senior leaders bought Claude licenses from Anthropic and then assigned staff to implement the tools, with some employees saying they were 'voluntold' into the work.1
- Editors say well-publicized cases of alleged AI-written books are only part of a wider pattern of undisclosed AI use and cancellations tied to AI use.1
