The verdict on Perplexity Comet: Researchers who want an AI browser that can navigate and extract information across multiple sites, not just answer a query Perplexity Comet is less a search tool and more a browser agent: it completes multi-step tasks across sites, filling forms and pulling information without you doing the clicking.

Overview
Perplexity Comet is Perplexity AI's autonomous AI browser, designed to extend the research and search capabilities of Perplexity's existing assistant into a full web navigation agent that can complete multi-step browser-based tasks on your behalf. Rather than returning search results or answers, Comet opens a browser, handles websites, fills forms, extracts information across multiple pages, and synthesizes findings into structured outputs, functioning as a research agent that uses the open web as its data source. The tool builds on Perplexity's core competency in cited, grounded answers: all information surfaced during browsing is attributed to its source, maintaining the factual accountability that distinguishes Perplexity from general AI chat tools.
Use cases span competitive research (visiting competitor websites and summarizing their pricing and features), data gathering (collecting structured information from multiple sites in a single session), and form-based tasks (filling out inquiries or registrations across multiple sites). Comet launched in 2025 as part of Perplexity's expansion from search tool to agentic platform. Access is available through Perplexity's premium subscription tiers.
Comet positions Perplexity in the emerging AI browser and agent category alongside tools like Browser Use and Anthropic's computer use capabilities, bringing Perplexity's search-accuracy focus to autonomous web task execution.
Our Take
That's a meaningfully different capability from answering a single query, and it's the right frame for evaluating it. The core access is free and available to everyone since October 2025, but the most capable research features sit behind the Pro plan. It's still maturing as a product. Researchers who regularly need to gather information across multiple sites, not just get an answer to a single question, are the best early fit.
