About Perplexity Comet
Perplexity Comet is a standalone browser for Mac, Windows, iOS, and Android built around AI from the ground up. Unlike adding an AI extension to Chrome, Comet bakes agentic search, live page summarization, voice mode, shopping assistance, and Deep Research directly into the browsing experience. The browser agent -- powered by Claude Opus by default -- can navigate pages, fill forms, and carry out multi-step tasks autonomously while you watch or step away. Comet went free worldwide in early 2026 after launching as a $200/month exclusive. No account is required for basic browsing; a Perplexity Pro subscription unlocks the full AI feature set.

Why People Use It
Comet is the clearest example of what an AI-native browser looks like in practice -- not Chrome with a sidebar, but a browser redesigned around the assumption that AI should handle navigation, research, and multi-step tasks automatically. It is particularly useful for anyone who spends significant time on research, comparison shopping, or repetitive web workflows.
