FAQ
No. Perplexity is a standalone AI search and answer engine. Perplexity Comet is a separate AI browser product from Perplexity that works as an assistant inside your browsing session rather than as a query-answer interface.
Perplexity handles research questions well from its own interface, but it does not operate at the browser layer. Comet is built specifically for tab-aware tasks and browser-side assistance that Perplexity's core product is not designed for.
