# Perplexity

## Perplexity

**Type:** Product (AI Search Engine) 
**URL:** https://www.perplexity.ai/

An AI-powered search engine that aggregates real-time web data and provides cited, synthesized answers. Mentioned by [[entity-lior-weinstein|Lior Weinstein]] as the exemplar of a Level 1 "Oracle" tool in the [[framework-ai-interaction-levels|Three Levels of AI Interaction]].

Perplexity goes beyond traditional search by synthesizing multiple sources into a coherent answer with citations—an evolution of the Oracle concept, but still fundamentally reactive (you must ask the right question).
