Perplexity
AI answer engine that searches the web and answers with cited sources
An AI answer engine: a user asks a question in plain words, and it searches the live web and writes an answer from what it finds rather than returning a list of links. Perplexity: "Each response includes citations and links to original sources, enabling you to verify the information and explore topics in greater depth." Users can choose which AI model writes the answer, including OpenAI's GPT models and Anthropic's Claude.
