Perplexity

Perplexity とは？

Perplexity is an AI-powered answer engine. Instead of returning a list of links, it searches the web, reads the results and writes a direct answer with numbered citations, so you can check where each point came from. It is aimed at people who research often, such as students, analysts, journalists and curious readers. Its main difference from a general chatbot is the focus on sourced, up-to-date answers. You can ask follow-up questions in the same thread, upload files to ask about them, run deeper research that covers more sources, and organize related searches into Spaces.
