An expert AI harness that controls what a model reads and measures how it answers
Defines which documents and internal sources a language model may read, restricting answers to approved material.
Measures and records how an answer was assembled so outputs can be audited and reproduced.
Applies a decade of NLP work on technical literature and patents to interpret dense scientific language.
Turns unstructured documents and enterprise data into structured, AI-ready intelligence.
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.
Offers deeper conversational reasoning and coding agents, but lacks Perplexity's dedicated inline citation-first search layout.
