Open-source RAG platform for building enterprise AI agents
Upload documents or crawl web sources with automatic text splitting, vectorization, and retrieval to ground answers in your own knowledge.
Orchestrate multi-step AI processes with a function library and MCP tool-use for complex business logic.
Connect private models such as DeepSeek, Llama and Qwen or public APIs including OpenAI, Claude and Gemini.
Embed intelligent Q&A into existing business systems and third-party apps without writing code.
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.

#1
Leverages Google's vast search index for real-time answers, but offers a standard chat interface rather than deep research feeds.
#2Provides exceptional analytical depth and writing quality, but does not focus purely on web-sourced search summaries.
Free / Open-sourceHigh-efficiency open-weight and hosted reasoning AI powered by DeepSeek-V4 and R1 at ultra-low token costs.

Integrates real-time social data search for breaking news, but leans more toward casual chat than structured research.

The AI workspace where teams and agents get work done together

Delivers agentic multi-source research and page generation, but can feel more cluttered than Perplexity's clean answer engine.

SpecialistOffers a comprehensive free index of academic literature, but lacks conversational chat synthesis for general web queries.


SpecialistFocuses exclusively on peer-reviewed scientific papers for evidence-based answers, unlike Perplexity's broad general web search.


Combines privacy-focused web search with AI summarization, though it requires a paid subscription for full access.

Chat with 30+ leading AI models in one clean, fast workspace
SpecialistAnalyzes scholarly article citations to verify scientific claims, making it superior for academic literature reviews.
