Comet
Perplexity's AI-native browser with an agent built into the address bar.
Last updated by Faisal Saleem · Filed under Search & Research
Perplexity's AI-native browser — an agent in the address bar that browses, summarizes, and does tasks across your tabs.
Comet is the most convincing case yet that the browser itself is the next AI battleground: the agent isn't a sidebar bolt-on, it's woven into how you browse, and it genuinely completes multi-step tasks across tabs. It's now free and runs your Chrome extensions, so trying it costs nothing. Whether you switch full-time depends on how much you trust an agent with your logged-in sessions — but as a research and task browser, it's a real step beyond Chrome-plus-a-chatbot.
About this tool
Comet is Perplexity's AI-native browser — the first mainstream browser built around an agent rather than bolting AI on as an add-on. Its assistant lives in the address bar and side panel, and can navigate, summarize pages, pull data across tabs, and complete multi-step tasks on your behalf. It renders normal web pages, runs Chrome extensions, and imports your bookmarks and passwords, so it can replace your default browser. Originally a $200/month product, Comet went free in March 2026, with paid Pro and Max tiers adding higher limits and deeper automation.
