What is Perplexity?

Insta's plain English

An AI "answer engine" that replies to questions with cited, synthesised answers instead of a list of links.

Perplexity is an AI-powered answer engine that responds to questions with synthesised, cited answers drawn from the web, positioning itself as an alternative to traditional search.

The full picture

Perplexity reimagines search: rather than returning ten blue links, it reads multiple sources and writes a direct, cited answer. It has grown quickly in users and revenue and expanded into on-device and enterprise products.

It also sits at the centre of the AI-copyright fight — publishers including CNN have sued it over how it uses their content, while others have signed licensing deals. For businesses, Perplexity is both a useful research and competitive-intelligence tool and a case study in the legal tensions around AI and content. Its conversational, answer-first model also previews how AI is reshaping search and discovery.

📌 Real business example

A market-research team uses Perplexity to get fast, sourced briefings on competitors, then clicks through the citations to verify the underlying facts before acting.
