What is Comet?

Comet is Perplexity's AI-first web browser, built around the idea that the assistant should browse with you rather than wait in a separate tab. A sidebar assistant reads the page you are on, summarises it, compares products across tabs, drafts replies and can carry out multi-step tasks like booking research or filling routine forms under your supervision.

Under the hood it runs on Chromium, so Chrome extensions and familiar browsing carry over, and Perplexity's answer engine powers its search. Comet is free to download, with heavier agent usage and premium models reserved for paid Perplexity plans. Letting an agent act on logged-in pages raises real security questions, and researchers have demonstrated prompt-injection tricks against browsing agents generally.
