Perplexity

Perplexity is an AI-powered answer engine that combines real-time web search with large language models to deliver direct, cited answers instead of just a list of links. It is used for research, learning, coding help, and everyday questions by students, professionals, and teams who want fast, source-backed information. Perplexity is an AI answer engine that searches the web, reads multiple sources, and synthesizes a concise, citation-rich response, with options to drill down, browse sources, run Deep Research, and switch between top-tier AI models.

Core features
Real-time web search plus AI synthesis, returning one coherent answer with inline citations you can click through.
Multiple AI models (GPT‑4.1/4o/5, Claude 4.x, Gemini Pro, xAI Grok, and Perplexity’s own Sonar/R1-series models) selectable per thread.
Deep Research mode that runs dozens of searches automatically and compiles multi-section reports from hundreds of sources.
File and link uploads so the AI can analyze PDFs, docs, slides, and web pages, with source-aware answers and summaries.
Multi-modal support for images and voice, including image understanding and image generation via integrated models.
