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.
Legal research and citation linking, built into your browser
The extension scans the page you are reading and turns case names, citations and statutory references into clickable links that open the matching document on vLex.com, so you can verify authority without leaving your tab.
Vincent AI reads the context of the content in front of you and recommends relevant vLex cases, statutes and commentary, letting you explore the surrounding legal landscape in one click.
Search results are augmented with related vLex documents, so case law, legislation and secondary sources appear beside ordinary web results instead of being buried several pages deep.
Beyond the extension, Vincent AI accepts natural-language legal questions and returns structured answers with linked citations, and can generate multi-jurisdiction surveys for comparative work.
