# What is Perplexity AI's Deep Research mode?
## Overview Perplexity's Deep Research mode functions as a personal research assistant that performs extensive web analysis. Unlike standard search, it "performs dozens of searches, scans a large number of web pages and documents, and iteratively analyzes information to compile a comprehensive answer."
## How It Works The feature typically requires 2-4 minutes to process queries. During this time, Perplexity conducts multiple searches, consults various sources, and synthesizes findings into structured reports. The process mimics expert research methodology: locating sources, extracting key information, and producing coherent analysis.
**Example use case:** A query about economic impacts of AI in finance might yield statistics, article citations, data interpretation, and contextual insights formatted as a complete report.
## Best Use Cases Deep Research excels for: - Open-ended, complex questions - In-depth topics (finance, marketing, technology, history, health) - Mini-reports, comparative analysis, and pros/cons evaluations - Tasks requiring multi-source synthesis
It's slower than regular search but significantly faster than manual research.
## How to Use 1. Access the Perplexity website or app 2. Select "Research" mode from the mode selector 3. Submit your query 4. Monitor progress indicators 5. Review structured results with citations 6. Export reports (PDF, document formats) as needed
## Key Benefits - Saves significant time on research tasks - Provides expert-level analysis - Ideal for students, professionals, and curious learners - Currently free with daily limits; Pro subscriptions available for unlimited queries
