🧠 What is Perplexity AI?
Perplexity AI is an AI-powered search engine and conversational assistant. Unlike traditional search engines like Google, Perplexity doesn't just return a list of links — it provides direct answers with real-time data backed by sources. It allows users to ask complex questions and receive multi-model, context-aware answers, similar to how you’d interact with ChatGPT — but enhanced with up-to-date search results.
🔍 Core Idea:
Real-time search + LLM reasoning + citation = Intelligent, trustworthy answers.
