Perplexity AI is a conversational search engine that leverages advanced language models to provide direct, concise, and, above all, cited answers. Unlike traditional search engines, it does not present a list of links; instead, it processes information found on the web in real-time to respond naturally to questions. Its main feature is the precise citation of the sources used, ensuring transparency and verifiability of information. It also includes a 'Copilot' mode that helps refine search queries to obtain more relevant and in-depth results. Developed by a team with experience at Google and OpenAI, it positions itself as a hybrid between a classic search engine and an AI chatbot.
