Perplexity

What is Perplexity?

Perplexity is an AI answer engine that responds to questions in natural language and attaches inline citations so you can see where each claim comes from. It routes each query across several leading models, including ChatGPT, Google Gemini, Anthropic Claude and NVIDIA Nemotron, and paid plans let you pick a preferred model. The paid tiers add deep research, premium data sources such as PitchBook, Statista and S&P Capital IQ, search across the web, your files and connected apps, and Perplexity Computer, which runs multi-step tasks and builds documents, spreadsheets and apps. A Comet browser assistant, image and video generation and more than 400 app connectors are part of the higher plans. The Free plan covers search with citations and basic models, Pro is US$17 a month billed annually, and Max is US$167 a month billed annually. Enterprise plans add admin controls, SSO and no training on customer data. Students, analysts, writers and teams use it for research and everyday questions.
