Perplexity AI is a modern conversational search engine designed to replace traditional link-based search engines. Rather than returning a list of sponsored blue links, Perplexity scours the live internet, reads multiple primary sources, and generates a structured answer with inline citations. Users can switch between Focus modes (Academic, Writing, Wolfram|Alpha, YouTube, Reddit) and conduct deep Pro Searches.
