Perplexity AI Search
What is Perplexity AI Search?
Perplexity AI search is an AI-powered search engine that answers user queries by retrieving real-time web content and synthesizing it into conversational responses with inline source citations. It is the purest form of AI search: real-time retrieval meets conversational UX, with full transparency about which sources informed the answer.
How Perplexity works
Perplexity is built on retrieval-augmented generation. For every query, it:
- Searches the live web for relevant content
- Ranks retrieved pages by relevance and authority
- Synthesizes a conversational answer from the top sources
- Provides inline citations with clickable links to every source
This architecture means Perplexity is effectively a hybrid: AI-powered synthesis with search-engine-level source transparency. For brands, the citation model is powerful: when Perplexity cites your domain, users can click directly to your content.
Perplexity has grown rapidly, with millions of daily queries and a user base that skews toward research-heavy, high-intent information seekers.
