Perplexity

Perplexity is an answer engine powered by AI: it answers questions in natural language by drawing on real-time web search, and cites its sources. It's a hybrid between a search engine and a conversational assistant, valued for the reliability of its sourced answers.

What is Perplexity used for?

You ask a question, Perplexity searches the web, synthesizes an answer, and shows the cited sources, so you can verify. It handles follow-up conversations, file analysis, and, on higher plans, deep research and an agent capable of taking actions. Its strength: combining up-to-date web information with an assistant's synthesis, with a strong emphasis on traceability.

Perplexity or ChatGPT?

Compared to general-purpose tools like ChatGPT or Le Chat, Perplexity specializes in sourced search and fact-checking. Compared to Gemini, it prioritizes systematically citing sources. For research, monitoring, and work where the origin of information matters, it's a go-to tool.
