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, offline notebook that turns your own sources into reports, decks and briefings
Install a normal desktop app on Windows, macOS or Linux and run it with no account. With a local model you can pull the network cable and keep querying your indexed sources, since nothing is sent to a vendor.
Choose a bundled local Qwen or Gemma model at first launch, or paste a key for OpenAI, Anthropic or any OpenAI-compatible endpoint. The model is a setting rather than a fixed vendor choice.
Turn one set of sources into slide decks, reports, briefing notes, podcasts, mind maps, flashcards, quizzes, Markdown, Word, PDF, HTML and spreadsheet outputs — generated and stored locally.
Optional plugins pull research from Google Search, Reddit, YouTube, Instagram, TikTok, Google Maps, Amazon, Walmart, Indeed and the open web, and anyone can register their own MCP server.
