Perplexity

What it is

Perplexity is an AI-powered answer engine that combines web search with language models to deliver cited, current answers in seconds. Unlike a traditional search engine that returns links, Perplexity synthesizes information from multiple sources and shows you exactly which pages it used. It supports focused search modes for coding questions, academic research and visual search.

Highlights

• Real-time web search: results powered by current sources, not training data
• Cited sources: every claim links to the page it came from
• Specialized search modes: focus on academics, code, images or analysis
• Multiple model support: choose between different AI providers
• Conversational follow-ups: refine your questions in a chat thread

Who it's for

Ideal for researchers, students, developers and knowledge workers who need accurate, up-to-date information fast. Perplexity offers free access with limited queries; Pro plans include priority inference and longer threads.
