Perplexity AI is an AI-powered search and answer engine that combines the capabilities of large language models with real-time web search to deliver accurate, up-to-date, and well-sourced information. Founded in 2022 and headquartered in San Francisco, Perplexity aims to redefine how people find and interact with knowledge online.
Unlike traditional search engines that return a list of links, Perplexity provides concise, conversational answers directly in response to user queries—similar to a chatbot—but with a strong emphasis on citations and source transparency. It cites references from the web, academic papers, news outlets, and other credible sources, allowing users to verify information easily.
Key features include:
Real-time web search integrated with generative AI
Support for follow-up questions in a chat-like interface
Multiple AI model options (including its own proprietary models and integrations with Claude, GPT, and others)
“Copilot” mode for guided, interactive research
Focus on accuracy, efficiency, and reducing hallucinations
Perplexity is widely used by researchers, students, professionals, and curious learners seeking reliable answers without sifting through pages of search results. Its mission is to build an “answer engine” that’s both intelligent and trustworthy—making knowledge access faster, clearer, and more transparent.
