About Us
Founded in 2022 by former Google researcher Aravind Srinivas, Perplexity AI is headquartered in San Francisco and aims to redefine how people access information. Unlike traditional search engines, Perplexity uses a conversational interface combined with large language models (like GPT-4, Claude 3) and real-time web search to provide synthesized, refined answers rather than simple link lists. This "answer engine" model greatly improves information retrieval efficiency, especially suitable for research, learning, and decision-making scenarios requiring quick access to accurate information. In 2024, Perplexity secured multiple funding rounds with a valuation exceeding $1 billion, becoming a unicorn in the AI search space. Currently serving over 10 million monthly active users, highly favored by students, researchers, and professionals.
