Perplexity is an AI answer engine built around web search. Unlike a chat assistant that often answers from memory, Perplexity retrieves and cites web sources for nearly every answer, which makes it the most citation-forward of the major AI platforms.
For brand visibility, this citation focus means being a source Perplexity retrieves is central to appearing in its answers. It draws notably on community discussion and other current web content, so being present and cited across the sources it trusts for your category matters. It is one of the eight surfaces Diploria tracks.
