Earlier quoted context omitted.
"Amazon DID NOT answer PubLunch’s questions about “what rights the company was relying upon to execute the new feature was not answered, nor did they elaborate on the technical details of the service and any protections involved (whether to prevent against hallucinations, or to protect the text from AI training).”
You don’t need any rights to execute the feature. The user owns the book. The app lets the user feed the book into an LLM, as is absolutely their right, and asks questions.
2. I doubt the Kindle version of the LLM will run locally. Is Amazon repurposing the author-provided files, or will the users' device upload the text of the book?
