Overview

What is Perplexity AI?

Perplexity AI is an AI search engine that combines large language models with real-time web search. It understands complex questions, gathers information from multiple sources, and generates structured answers with reference links.

Unlike traditional search engines, Perplexity gives answers directly instead of a list of links, which greatly improves the efficiency of information acquisition.
