Frequently asked questions
Is Perplexity a search engine or a chatbot?
It is an answer engine: it searches the web, reads the results and writes a direct answer with sources, instead of giving you a list of links.
Can I trust Perplexity citations?
Citations point to real pages, which is a big step up from ungrounded chatbots. You should still open the source for anything important, because summaries can miss nuance.
What does Perplexity Pro add?
