Overview
Perplexity is an AI-powered answer engine that combines conversational AI with real-time web search. It is designed to provide accurate answers, source citations, research assistance, and up-to-date information by pulling information directly from the web and presenting it in an easy-to-understand format.
Recent Updates
Key takeaway: On August 13, 2026, Perplexity launched the Agent API, a single programmable endpoint that combines web search, URL fetching, code execution, and agent capabilities for developers building AI-powered research and automation tools.
Previously, developers who wanted an AI system to search the web, read pages, run code, and take actions typically had to connect several separate services. The Agent API packages these capabilities into one call, which simplifies building research assistants, automation workflows, and agent applications. For students learning to build with AI, the Agent API is a practical way to experiment with search-and-act agents without managing multiple integrations, and it continues Perplexity’s expansion from a consumer answer engine into a developer platform.
