Perplexity is an AI answer engine that combines web search with LLM reasoning and inline source citations. Combines real-time web search with large language model reasoning to generate answers.
About Perplexity
Perplexity is an AI answer engine — it pairs real-time web search with LLM reasoning and cites its sources inline.
Its whole model is answers with receipts: every response links to the original sources it used, it runs multiple LLM backends including OpenAI and Anthropic models, and it's on web plus native macOS, iOS, and Android.
It fits people who want researched answers with citations rather than a blank-slate chat. Two caveats: the free tier caps Pro searches per day, and because answers lean on live web search, it depends on internet connectivity.
It's the search-grounded answer engine, distinct from the open-chat assistants like ChatGPT, Claude, and Gemini.
