Perplexity 是什么？
Perplexity is an answer engine that responds to questions with cited, real-time web sources. Instead of a chatbot that writes from memory, it searches the web and shows where each answer came from.
Compared with ChatGPT, it is more research-first; compared with a traditional search engine, it summarizes rather than just listing links. Pro adds deeper research modes and file uploads.
