# Comet AI

**Comet AI** is an AI shopping assistant owned by [[entity-perplexity]]. It became the subject of a major legal battle when [[entity-amazon-d4]] sought a preliminary injunction to block it from accessing Amazon's website — the [[entity-amazon-comet-lawsuit]]. Comet is a concrete instance of the third-party agent that platforms attempt to *Resist* in [[framework-platform-response]].
