Perplexity AI

Perplexity AI is a conversational answer engine: it uses large language models and real-time web search to deliver direct, summarized answers with verifiable source citations.

This is an AI-powered research tool, not a traditional search engine. Perplexity synthesizes information using advanced LLMs (like GPT-4 Omni or Claude 3) to provide a concise, factual answer, bypassing the usual list of links. Its core value is transparency: every statement includes clickable, real-time source references (SRs), a major differentiator from black-box chatbots. Founded by CEO Aravind Srinivas, the company has secured significant funding, with a 2024 valuation between $2.5 billion and $3 billion, confirming its position as a serious player in the information retrieval space. Users leverage features like Copilot for guided research and specialized Focus modes (Academic, Writing) for targeted results.
