According to a report from Reuters, ChatGPT is listed as the author or co-author of at least 200 books on Amazon’s Kindle Store. However, the number of bot-written books is likely higher than that since Amazon’s policies don’t require authors to disclose their use of AI.

Brett Schickler published on the Kindle Store a children’s book written and illustrated by AI. Although Schickler says the book has earned him less than $100 since its January release, he only spent a few hours creating it with ChatGPT prompts like “write a story about a dad teaching his son about financial literacy.”
