Comet is an AI browser introduced by Perplexity, featuring a built-in assistant that not only answers questions but also helps you complete tasks across websites, such as comparing data, filling out forms, and organizing research results.
Difference from traditional browsers
Comet combines Perplexity's instant search and reference capabilities with proxy functionality. You can ask it to 'summarize the key points from these tabs' and it will read the tabs and provide a sourced summary, reducing the need for manual switching.
Usage notes
Proxy operations involve granting AI permission to act on your behalf, so be cautious with authorization scope and account security. Sensitive operations should still be confirmed by humans. This represents a shift in the browser's role from 'viewing information' to 'doing tasks for you'.

Editor's Note
As browsers start 'doing things for you', convenience and risk are two sides of the same coin. Set your own boundaries for authorization.
