Amazon has demanded that Perplexity AI stop its AI browser agent, Comet, from making purchases on Amazon's site, sending the startup a cease-and-desist letter. The e-commerce giant accused Perplexity of computer fraud and violating its terms of service, stating that the AI agent diminishes the shopping experience and poses privacy risks for customers. In response, Perplexity AI's CEO Aravind Srinivas publicly accused Amazon of anti-competitive behavior and attempting to stifle innovation to protect its advertising-driven business model. This confrontation highlights the growing tension between established tech giants and emerging AI companies seeking to change how users interact with the web and online retail.
