Comet browser by Perplexity AI is an AI-enhanced web browser based on Chromium that integrates AI agents to assist with complex tasks such as booking, email drafting, shopping, organizing tabs, and summarizing web content. Initially launched in July 2025 for Perplexity Max subscribers at $200 per month, it has since become free and available to all users, aiming to compete seriously with browsers like Google Chrome.
