Perplexity AI

AI-powered search platform that answers questions with real-time web retrieval and cited sources. Combines large language models with live web indexing so responses are grounded in current information, with numbered inline citations that link back to source URLs.

Perplexity serves over 20,000 organizations with its Enterprise offering, which includes SOC 2 Type II, GDPR, and HIPAA compliance, integration with internal files and external web, plus SSO and SCIM. Unlike chat models that rely on static training data, Perplexity runs real-time web search for every query and cites sources from its index of web content.

Key capabilities:

• Agent API: access to third-party models from OpenAI, Anthropic, Google, and xAI with integrated web search and tool configuration
• Search API: raw ranked web results with domain filters, language selection, and date-based filtering
• Sonar API: web-grounded responses with built-in citations and conversation context
• Embeddings API for semantic search and RAG pipelines
• Python and JavaScript SDKs, REST endpoints, streaming support

Build research assistants, fact-checking tools, and customer-facing Q&A that stays up to date. Developers integrate Perplexity for applications that require cited, verifiable answers rather than unsourced model output, such as financial news aggregation, competitive intelligence, and documentation search.
