Overview
Perplexity is an AI answer engine focused on web research and source-backed responses. Its official product pages describe cited answers, deeper research, parallel multi-model orchestration, web-first agents, a computer workspace for multi-step tasks, and an API platform. The service is aimed at people researching companies, markets, and general topics, as well as developers building search-grounded applications. Perplexity also presents browser-based products and work flows, but the hosted answer engine is proprietary and no official GitHub repository for the product itself was found.
