Real-time AI answer engine and research workspace combining live web citations with frontier reasoning models.
Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
Affordable real-time search API that returns structured JSON plus page content in a single call.
Send a query and receive live web results as clean, structured JSON that is ready for parsing, ranking or feeding into a model.
Convert any URL into clean, readable markdown in the same API key, removing boilerplate so retrieved text is directly usable for RAG and summarization.
Requests are routed across multiple underlying search sources with health monitoring and automatic retries, so a single empty source does not break your pipeline.
Official libraries and snippets for Python, JavaScript, MCP and LangChain make it a few lines of code to add live search to an agent or app.
