Perplexity AI, backed by Nvidia, unveils 'Comet,' an AI-powered web browser designed to surpass traditional search models by providing users with agent-like functionality. By allowing users to ask questions, compare products, and summarize webpages, Comet targets productivity. Priced at $200/month for Perplexity Max subscribers, the browser emphasizes data privacy, storing information locally. Despite entering a market dominated by Google Chrome's 68% share, Perplexity aims to leverage growing demand for AI-native tools and address copyright issues through a new publisher partnership program.
