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.
Independent web search and agent grounding API built on the Ahrefs index
Submit a query and receive ranked pages, not just links, from an independent index so you are not dependent on a single commercial search provider.
Each result includes the passages that answer the query, so a language model can read relevant context without parsing entire pages.
A single endpoint call returns open-web context for your model, designed for RAG and agent grounding workflows.
Roughly 100 billion pages crawled since 2010 with around 8 billion refreshed every 24 hours, which keeps results reasonably current.
