What is the Amazon vs Perplexity AI Comet browser case?
Amazon has sued Perplexity AI over its Comet browser, which allows an AI assistant to log into user accounts and make purchases autonomously. Filed in a California court, the case could shape 'agentic commerce' and redefine control over online shopping, user data, and Amazon’s $50 billion ad business, testing how far AI can act on behalf of humans.
