Perplexity AI
AI answer engine that delivers cited, synthesized responses from web search.
About Perplexity AI
Perplexity AI is a conversational answer engine that searches the web in real time and returns a synthesized, cited response instead of a list of links. Users can ask follow-up questions to dig deeper into a topic, and the underlying index is continually updated, with the company reporting that it processes tens of thousands of documents per second. Beyond the consumer product, Perplexity offers a developer API Platform with four components: an Agent API that can search the web, call tools, and reason across multiple turns; a Search API giving direct access to its retrieval index; an Embeddings API for building semantic search and RAG applications; and an upcoming Sandbox API. The platform is model-agnostic, letting developers compare answers from different underlying models for the same query through a "Multi-model Council" feature. Perplexity is available as a web app, browser extensions, and native apps for iOS, Android, macOS, and Windows, making it usable both as a search replacement for everyday users and as infrastructure for other applications. Because answers depend on live web retrieval, quality can vary with how well a topic is covered by indexed sources.
