Perplexity AI is a conversational search engine that uses large language models (LLMs) to answer queries. Its developer, Perplexity AI, Inc., is based in San Francisco, California.

Founded in 2022, Perplexity generates answers using sources from the web and cites links within the text response.[2] Perplexity works on a freemium model; the free product uses the company's standalone LLM, while the paid version Perplexity Pro has access to GPT-4, Claude 3.5, Grok-2, Llama 3 and in-house Perplexity LLMs.[3][2][1] In Q1 2024, it had reached 15 million monthly users.[4]
