What happened
Amazon issued a cease-and-desist to Perplexity AI, demanding the cessation of its Comet AI browser agent's purchasing activities on Amazon's platform. Amazon alleges Comet violates terms of service by failing to disclose its AI agent status, potentially constituting computer fraud, degrading user experience, and introducing privacy vulnerabilities. Perplexity contends Comet operates as a user-authorised agent, not a prohibited bot. This follows a November 2024 request from Amazon, which Perplexity initially honoured, but Comet subsequently resumed purchases, reportedly masking itself as a Chrome browser.
Why it matters
The alleged masking of AI agents as standard browser traffic introduces a significant visibility gap for platform operators and IT security teams. This weakens existing bot detection and user agent identification controls, increasing exposure to non-compliant automated activities that bypass established terms of service. Compliance teams face higher due diligence requirements to differentiate between legitimate user actions and AI-driven transactions, potentially impacting fraud detection and platform integrity. This places an increased oversight burden on platform operators to maintain service quality and security.
