Amazon has sent a cease-and-desist notice to Perplexity AI, demanding that its Comet assistant cease operations on Amazon's platform. The tech giant alleges that Perplexity's AI agents simulate human behavior, breaching Amazon's terms of service and negatively impacting user experience. Perplexity has rejected these claims, labeling them as bullying and emphasizing that the issue revolves around user autonomy. The company maintains that Comet operates using user credentials stored locally, not as a bot or data-mining tool. This dispute underscores ongoing tensions regarding the regulation of AI agents in the e-commerce sector.
