Amazon has issued a cease-and-desist letter to Perplexity AI, demanding that the startup halt its AI tool, Comet, from making online purchases on behalf of users. The AI tool Comet is designed to facilitate online transactions autonomously, which has prompted Amazon's legal action. This move reflects Amazon's concerns about the implications of AI technologies operating within the e-commerce space without explicit authorization. The cease-and-desist order underscores the challenges companies face as AI tools increasingly interact with commercial platforms. Perplexity AI's Comet tool's ability to make purchases autonomously raises questions about control, security, and compliance in digital marketplaces. Amazon's demand aims to prevent potential unauthorized transactions and protect its platform's integrity. This development highlights the evolving intersection of AI capabilities and regulatory responses in the online retail sector.
