About Perplexity Comet
Perplexity Comet is a web browser built by Perplexity around its AI answer engine. An assistant lives in a sidebar next to the page being viewed, so users can ask questions about the content, and an agentic mode can work through multi-step tasks in the browser on the user's behalf.
Comet is a proprietary product that depends on Perplexity's hosted AI services rather than anything you run yourself. Platform support, plan options and data handling details should be confirmed on Perplexity's website.
