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.
AI pre-submission reviewer and writing coauthor for researchers
Upload a draft as PDF or Word and get a full reviewer-style report covering argument, methodology, evidence, structure and clarity, with findings graded by severity.
Relevant articles are matched from an index of 200M+ peer-reviewed papers, and the platform explicitly avoids fabricating citations that do not exist.
Get a ranked shortlist of venues matched to your manuscript, with fit, impact factor and selectivity detail to help you choose where to submit.
Agents search sources, read your PDFs and edit your document, with automatic version history, live co-author collaboration and LaTeX-to-PDF compilation.
