Perplexity
What is Perplexity.ai?
Perplexity.ai is an AI-powered conversational search engine that combines the strengths of a traditional search tool with the convenience of a chatbot. Instead of just giving you a list of links, Perplexity provides clear, natural-language answers—complete with real-time sources and citations you can verify. Its core design focuses on clarity, trust, and efficiency.
How It Works
Real-Time Web Results
Rather than simply returning search links, Perplexity scans the web in real time and generates concise, easy-to-read summaries, with clickable citations so you can confirm the information.
Conversational and Context-Aware
Like chatting with ChatGPT, you can keep asking follow-up questions or refine your query, and Perplexity will maintain context within the same conversation thread, giving you coherent and progressively deeper answers.
