About Comet
Comet is Perplexity's agentic browser that can browse, book, shop, and research on your behalf.
Its edge is the built-in agent: it can autonomously perform web tasks like booking, shopping, and researching, and it integrates Perplexity's AI search directly into browsing through an assistant sidebar. It's built on Chromium, so it works with existing Chrome extensions and web standards, and runs natively on macOS and Windows.
It suits people who want an agent-driven browser and already pay for Perplexity, since access requires a paid subscription with no free tier. It's not for Linux or mobile users, and as a relatively new product it may have stability issues or a narrower extension ecosystem than established browsers.
Against mainstream browsers, Comet trades broad platform reach for a native Perplexity agent baked into browsing.
