Perplexity AI

What is Perplexity AI?

Perplexity AI is an AI-powered answer engine that redefines online search. Founded in 2022 by Aravind Srinivas (ex-OpenAI) and Denis Yarats (ex-Meta), this California-based startup combines real-time web search with large language models to deliver direct, concise, and always-sourced answers.

An Answer Engine, Not Links

Unlike Google which displays lists of links, Perplexity provides synthesized answers with verifiable inline citations. Every claim is accompanied by a clickable source, significantly reducing the hallucinations typical of AI chatbots.

Cutting-Edge AI Models

Pro users access a range of frontier models: GPT-4o, Claude Sonnet, Mistral, and the proprietary Sonar model. Perplexity Labs even lets you test the latest experimental models. In 2026, Perplexity Computer orchestrates multiple models simultaneously for complex tasks.

Deep Research and Advanced Search

The Deep Research feature generates comprehensive research reports in minutes, work that would take hours manually. Ideal for students, researchers, and professionals who need in-depth analysis with sources.

Multimodal and Versatile

Perplexity analyzes PDFs, images, CSV files, audio, and video. Image and video generation are integrated for Pro subscribers. File upload lets you ask questions about your own documents.

Collaborative Spaces

Spaces allow creating shared research environments with your team, with custom instructions and shared context. Enterprises benefit from SSO, SCIM controls, and audit logs.

API and Integrations

The Sonar API enables integrating Perplexity search into your applications. Native integrations exist with Slack, productivity tools, and organizational applications.
