Artificial Intelligence (AI) has transformed the way we search, learn, and interact with information. Tools such as ChatGPT, Gemini, and Claude deliver conversational assistance and knowledge generation. Among these, Perplexity AI has emerged as a distinctive platform that combines the convenience of a search engine with the clarity of an AI assistant. Perplexity aims to provide concise, source-backed answers in a conversational format so users spend less time sifting through links and more time getting accurate information.
What Is Perplexity AI?
Perplexity AI is an AI-powered answer engine that functions like a smart search tool and chatbot in one.
