About Perplexity AI
Perplexity AI is building an AI-native search engine that answers questions directly with cited sources rather than returning a list of links. Founded in 2022 by Aravind Srinivas (former researcher at OpenAI, DeepMind, and Google), Denis Yarats, Johnny Ho, and Andy Konwinski, Perplexity represents the most credible threat to Google's search monopoly in a generation.
Perplexity's product combines real-time web search with large language model reasoning. When you ask a question, Perplexity searches the web, reads the relevant sources, synthesizes an answer, and provides inline citations so you can verify every claim. This approach directly addresses the hallucination problem that plagues standalone LLMs — the model's response is grounded in current, verifiable sources.
The company has grown to over 15 million monthly active users and processed hundreds of millions of queries. Perplexity Pro ($20/mo) offers access to more powerful models and advanced features. The company has raised approximately $165 million and is valued at over $1 billion.
Technology & Approach
Perplexity combines retrieval-augmented generation (RAG) with real-time web crawling. The system issues search queries, retrieves and processes relevant web pages, and uses an LLM to synthesize a coherent answer with inline citations. Perplexity uses multiple underlying LLMs (including GPT-4, Claude, and its own fine-tuned models) and selects the best model for each query type. The company has built a custom web index and crawling infrastructure to reduce dependence on third-party search APIs.
