Overview
Perplexity AI is an AI-powered answer engine and developer platform that returns web-grounded answers, citations, and research results in real time. It provides a consumer-facing search/assistant experience (free tier and paid Pro tiers), a developer API platform (Search API and grounded LLMs known as Sonar models), and enterprise offerings. The platform emphasizes transparent sourcing (citations), multiple model options (quick facts to deep research), and integration-friendly APIs (OpenAI-compatible chat completions format). Documentation and guides are available on docs.perplexity.ai. Note: some consumer Pro and enterprise marketing pages were behind a JavaScript/cookie gate during scraping; Pro feature descriptions and enterprise details were taken from help-center comparisons, docs, and available product blurbs.

Key Features
Real-time Web Research
Queries are grounded in live web content so answers can include recent events and citations.
Search API (raw)
Returns raw search results (JSON) priced per request; useful for building custom search and aggregation features.
Sonar Grounded LLMs
Family of grounded LLM models (Sonar, Sonar Pro, Sonar Reasoning, Sonar Deep Research) that combine search context with generative answers.
Deep Research Mode
Exhaustive multi-step analysis with explicit citation tokens and reasoning tokens for transparent, detailed reports.
OpenAI-compatible API
Chat completions format compatibility so many OpenAI client libraries work with Perplexity endpoints.
Consumer Pro and Comet browser (product ecosystem)
Pro subscription unlocks advanced models and usage limits; Comet is an AI browser product for productivity (site mentions).
