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.

One AI agent for finding, reading and writing with real research
A single conversational agent handles discovery, paper reading, literature review, document analysis, writing and citations, so you do not switch between separate tools.
Turns a research question into a structured review with real sources, supporting APA, Harvard, MLA, Chicago and BibTeX output formats.
Upload a paper or document and ask questions about it, with answers grounded in the file and source or page references for traceability.
Automatically extracts findings, method, results, limitations and contributions, and can compare several papers in a structured table view.

Offers deeper conversational reasoning and coding agents, but lacks Perplexity's dedicated inline citation-first search layout.
