AI answer engine that cites the web sources behind each answer
Perplexity is an AI search assistant that answers questions in natural language and lists the web sources behind each answer, so claims can be checked. Follow-up questions keep context, deeper research modes run multi-step searches, and you can upload files to analyze. It runs on the web, desktop, mobile and as a browser extension, and the paid plan lets you choose between several AI models.
