Book publisher Chicken Soup for the Soul has sued several Big Tech companies in California federal court for allegedly misusing its content to train their AI systems. The lawsuit alleges that the companies downloaded bootleg copies of its books from "shadow libraries" for use in AI training. The publisher argues that its first-person narratives are uniquely suited to train AI to replicate authentic human voice, narrative pacing, emotional tone, and story structure. The tech companies have not responded to requests for comment.
