Every AI conversation, one open-source workspace
Connect OpenAI, Anthropic, Google, Azure, AWS Bedrock, Mistral, Groq, Ollama, OpenRouter and many more, then switch models inside a single conversation.
Build specialized agents that carry their own files, tools, reusable instructions and delegated subtasks with separate context.
Turn chat output into interactive apps, React or HTML pages and Mermaid diagrams, and execute code in multiple languages in an isolated sandbox.
Connect any tool or service through Model Context Protocol, and give any model live internet access with built-in search and reranking.
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.
