Comet Assistant

Comet Assistant is an AI browser agent developed by Perplexity that combines web research with browser automation.

Unlike a traditional AI search interface that primarily returns answers, Comet operates alongside the user's browser session. It can understand the content of open pages, analyze information across tabs, summarize sources, answer questions about what the user is viewing, and extract relevant information without requiring users to continually copy and paste content.

This makes Comet particularly useful for research workflows involving multiple sources. A user researching a company, market, technology or topic can open several sources and ask Comet to compare or synthesize information across those tabs. Perplexity specifically recommends grouping related research tabs so the assistant can analyze them together.

Comet goes beyond research assistance by performing actions in the browser. It can navigate websites, fill forms and execute certain workflows under user supervision. It can also work with services such as Gmail when the user grants the required access.

For researchers, analysts and knowledge workers, this combination of search + contextual analysis + cross-tab reasoning + browser actions makes Comet useful as a research agent rather than simply another AI search engine.
