About Perplexity
Perplexity is an AI-powered answer engine that replaces the traditional list of blue links with a sourced, conversational response. Each answer cites the web pages it draws from, lets the user follow up with related questions, and can be steered into focused modes like Academic, YouTube, Reddit or Writing. Under the hood Perplexity orchestrates models from OpenAI, Anthropic and its own Sonar family, choosing between them based on the task and the user's subscription. Pro users get unlimited Pro Search, deep research reports, file uploads, image generation and access to Spaces for grouping projects with custom instructions and shared sources. The company also ships the Comet AI browser, mobile apps with voice mode, and an API that exposes its retrieval stack to developers. Perplexity is popular with researchers, analysts, journalists and curious generalists who want answers with receipts.
