Perplexity

Perplexity, also known as Perplexity AI, is an AI-powered, conversational search engine that answers queries using natural language predictive text utilizing sources from around the internet. Perplexity performs real-time web searches to gather the most current information available across the Internet. Then, it summarizes the information in a cited format, using LLMs mainly only to preprocess the questions and summarize search results, which is intended to deliver up-to-date and well-sourced information. Perplexity describes itself this way: “unlike traditional search engines that present a list of links, Perplexity delivers synthesized information in a natural language format, complete with citations and follow-up suggestions for more refined searches.” The company’s mission is to “serve the world’s curiosity”.
