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.
A private, EU-hosted AI machine with files, software and persistent memory
Every workspace runs on servers the company operates inside the European Union, with AI models self-hosted on the same infrastructure rather than forwarded to external providers.
The machine remembers prior work and conversation context, so follow-up tasks pick up where the last one ended instead of starting from a blank chat.
Store and work on documents, and run software inside the same machine, keeping results and context together rather than scattered across multiple apps.
Attach external tools and services to your machine via built-in connectors or self-configured MCP servers, so the stack you already use is reachable from inside Rool.
Offers deeper conversational reasoning and coding agents, but lacks Perplexity's dedicated inline citation-first search layout.
