FYI, Amazon is now requiring KDP to disclose the use of generative-AI.

ARTIFICIAL INTELLIGENCE (AI) CONTENT (TEXT, IMAGES, OR TRANSLATIONS)
We require you to inform us of AI-generated content (text, images, or translations) when you publish a new book or make edits to and republish an existing book through KDP. AI-generated images include cover and interior images and artwork. You are not required to disclose AI-assisted content. We distinguish between AI-generated and AI-assisted content as follows:
AI-generated: We define AI-generated content as text, images, or translations created by an AI-based tool. If you used an AI-based tool to create the actual content (whether text, images, or translations), it is considered "AI-generated," even if you applied substantial edits afterwards.

AI-assisted: If you created the content yourself, and used AI-based tools to edit, refine, error-check, or otherwise improve that content (whether text or images), then it is considered "AI-assisted" and not “AI-generated.” Similarly, if you used an AI-based tool to brainstorm and generate ideas, but ultimately created the text or images yourself, this is also considered "AI-assisted" and not “AI-generated.” It is not necessary to inform us of the use of such tools or processes.

You are responsible for verifying that all AI-generated and/or AI-assisted content adheres to all content guidelines. For example, to confirm an AI-based tool did not create content based on copyrighted works, you're required to review and edit any AI tool outputs.
