Comet is Perplexity's AI-powered agentic web browser that can search, summarize, and take actions across the sites you're browsing, aimed at everyday users who want an assistant built directly into their browser rather than a separate chat window.
Who it's for
Comet is built for individuals — researchers, professionals, students, and generally curious users — who want an AI layer woven into normal browsing: summarizing a long article, comparing products across tabs, or handling small multi-step tasks like booking a reservation. It's a consumer product rather than a developer platform, so teams looking to build agent features into their own software should look at API-first tools instead.
How it works
Comet functions as a full web browser with an AI assistant built in that can see and interact with the pages you have open, answer questions using the content on the page, and carry out actions such as filling forms, navigating between sites, or pulling together information from multiple tabs into one answer. Because it operates through a real browser session rather than an API layer, it can act on essentially any website the way a person would, including sites without a public API. It's positioned as part of Perplexity's broader answer-engine product line, so search and citation-backed answers remain central to the experience.
Pricing
Comet has a free tier for general use, with full access tied to Perplexity's paid plans starting at roughly $20 per month. Because Comet's more advanced agentic features are generally reserved for paid Perplexity subscribers, casual users can try the free tier, but anyone wanting to lean on it for regular task automation should check Perplexity's current pricing page, since feature availability by tier has shifted since launch.
Strengths and trade-offs
Comet's strength is that it puts agentic browsing directly where people already spend their time — inside the browser — rather than requiring a separate app, and it's backed by Perplexity's search and citation strengths for answers grounded in real sources. The trade-off is that it's a consumer product without a published developer API or enterprise governance features such as audit logs in our data, so it's not the right choice for businesses wanting to build or govern agent behavior at scale. For individuals wanting an AI-assisted browser that can act on pages, not just answer questions about them, Comet is one of the more prominent options alongside OpenAI's ChatGPT Agent and the open-source Browser Use.
