Your team's SOPs, manuals and know-how in one AI assistant
Put a question to an AI assistant that has indexed your company documentation, SOPs and equipment manuals for fast on-the-job answers.
Turn centralised documentation into clear, repeatable processes team members can follow when they need more direction.
Give new hires a clear roadmap plus short quizzes and badge tracking that build and measure industry expertise.
Translate documentation so team members read directions in their preferred language, based on their mobile device settings.
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.
