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.

Definition

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.
