Perplexity AI is an answer engine that combines LLM reasoning with real-time web search, providing cited, up-to-date answers rather than raw search results. It supports follow-up questions, file uploads, and focused search on specific domains. Pro users gain access to more powerful models including GPT-4o and Claude, plus higher daily limits. The Perplexity API allows developers to build applications with real-time search capabilities.
