Perplexity is an AI-powered search engine that combines large language models with real-time web search to deliver accurate, sourced answers to any question. Unlike traditional chatbots that rely on training data, Perplexity actively searches the web for the most current information and presents answers with numbered citations linking to original sources, making it ideal for research, fact-checking, and staying updated on current events. The platform Pro Search feature conducts multi-step research, asking clarifying questions and refining its search strategy to provide comprehensive, well-researched answers. Perplexity supports file uploads for document analysis, image understanding for visual queries, and code execution for computational questions. It has become particularly popular among researchers, journalists, students, and professionals who need reliable information with verifiable sources. The Collections feature lets users organize their research into shareable libraries, and the Focus modes allow tailoring searches to specific domains like academic papers, YouTube, Reddit, or news. The free tier provides basic search with limited Pro searches, while the Pro plan at $20/month offers unlimited Pro Search, access to premium models like GPT-4o and Claude 3.5, and API access for developers.
