Perplexity
Tools & ProductsAn AI-powered search engine that answers questions with cited sources — combining the conversational nature of ChatGPT with the citation rigor of traditional search.
Perplexity represents a new category: AI-native search. Instead of returning 10 blue links, it reads multiple sources, synthesizes an answer, and cites every claim. You get a direct answer with verification, not a list of pages to read.
The platform combines web search (finding relevant sources), RAG (retrieving and processing source content), and LLM generation (synthesizing a coherent, cited answer). It supports follow-up questions, maintaining context across a research thread.
Perplexity is particularly strong for: research questions, current events (it searches the web in real-time), comparison queries, and any question where you want verified answers rather than AI-generated speculation.
