⚖️ Amazon has sued Perplexity alleging that Perplexity’s Comet browser runs an AI shopping agent that logs into Amazon with a user’s credentials, places orders, and browses while pretending to be a human, which Amazon says is a prohibited, covert automated access.
Amazon’s core claim is that Comet disguises bot traffic as normal clicks, so Amazon’s systems cannot apply its bot rules, audit trails, or safeguards that normally kick in for automation.
Amazon also says this automation enters private account areas, touches carts and checkout, and therefore creates security and fraud risk, because any script mistake or prompt misuse could buy the wrong item, ship to the wrong address, or expose sensitive data.
Amazon argues the agent breaks site terms and bypasses controls that govern third-party tools, instead of using approved interfaces or clearly identifying itself as an automated agent.
Amazon further claims the bot degrades the personalized shopping experience, because recommendations, pricing tests, and ranking are tuned for human behavior, not for rapid scripted requests.
Amazon also says it told Perplexity to stop but the agent kept operating, which strengthens Amazon’s position that this is knowing unauthorized access.
Perplexity’s defense is that the agent helps users comparison-shop and checkout on their behalf, with credentials stored locally, and that users should be free to pick their assistant even if Amazon dislikes the competitive impact.
So the fight is about who controls the logged-in session, whether a browser-based AI can act as the user inside Amazon, and whether it must self-identify as a bot instead of masquerading as a person.
