# Perplexity

**Perplexity** is an AI search-and-answer company and the owner of the AI shopping assistant [[entity-comet-ai]].

It was sued by [[entity-amazon-d4]] for allegedly concealing its agents to scrape Amazon's website data without approval — the [[entity-amazon-comet-lawsuit]], which the article uses as the prototype of the *Resist* posture in [[framework-platform-response]].
