Perplexity

Perplexity is the AI search engine that popularized the "answer engine" category: instead of returning a list of links like Google, it answers the question directly by synthesizing web sources in real time, and citing them. It is the best-known example of AI-augmented search.

Definition

The difference from "pure" ChatGPT or Claude: Perplexity searches the web on every question, so it knows today's news and cites verifiable sources. The difference from Google: it synthesizes instead of listing. This makes it well suited to market research, fact-checking recent events, and a first exploration of a topic.

For content producers, engines like Perplexity change SEO: the field of AEO (Answer Engine Optimization) is about structuring content so AIs cite it in their answers. Grace's pages are optimized with this in mind too.
