Perplexity AI

What is Perplexity AI?

Perplexity AI is an AI-powered answer engine that combines the power of large language models with real-time web search to deliver cited, source-backed answers to any question. Unlike traditional search engines that return a list of links to browse, Perplexity reads the relevant web pages for you, synthesises the key information, and presents a direct answer — with every factual claim linked to its source so you can verify it instantly.

Real-Time Web Search with Citations

Every Perplexity response includes inline citations — numbered references linking directly to the sources used to generate the answer. This transparency sets Perplexity apart from standard ChatGPT-style AI: you can click any claim to see the original source, verify the information, and dive deeper. The model searches live web pages, news sources, academic databases, and YouTube in real time — meaning answers are always current.

Deep Research Mode

Perplexity's Deep Research feature conducts multi-step research autonomously — breaking a complex research question into sub-queries, searching across dozens of sources, synthesising findings, and producing a comprehensive research report with full citations. Tasks that would take a human researcher hours are completed in minutes, with the sources available for full review.

Spaces — Collaborative Research

Spaces are shared research workspaces where teams can collaborate on research projects, share findings, and build a collective knowledge base grounded in cited sources. Spaces support file uploads so teams can ask questions about their own documents alongside web search, creating a powerful hybrid internal/external research environment.
