Core Features

1. Focus Modes (Narrow Your Search)

Available Modes:

• All: Broad web search (default)
• Academic: Scholarly articles, research papers
• Writing: Writing guides, style tips
• Wolfram: Math, science calculations
• YouTube: Video content
• Reddit: Community discussions
• Social: Twitter, social media posts

When to Use:

• Academic papers → Academic Focus
• How-to tutorials → Writing Focus
• Product opinions → Reddit Focus
• Scientific data → Wolfram Focus

2. Deep Research (Autonomous Research Assistant)

What It Does: Performs comprehensive multi-step research autonomously.

Process:

1. Breaks down your question into sub-questions
2. Performs dozens of targeted searches
3. Reads hundreds of sources
4. Reasons through material
5. Delivers structured report (2-4 mins)

Example Query:

Deep Research: What are the economic impacts of AI on manufacturing jobs in the US (2020-2025)?

Output: 2000-word report with sections, citations, data analysis.

Best For:

• Literature reviews
• Market research
• Competitive analysis
• Investment due diligence
• Academic research

Limitation: Takes 2-4 minutes (not instant).

3. Collections (Organized Research Spaces)

What They Are: Topic-specific workspaces with custom instructions.

Use Cases:

• Thesis Research: Collection for PhD topic with custom instructions about methodology
• Client Project: Organized research for consulting engagement
• Learning Topic: Curated knowledge base for skill development

Setup:

1. Create Collection
2. Add custom instructions (e.g., "Focus on peer-reviewed sources from 2020+")
3. Ask questions within Collection
4. All answers follow your instructions

Pro Tip: Share Collections with team members for collaborative research.

4. Follow-Up Questions (Conversational Research)

The Power: Don't treat Perplexity as one-and-done search. Have a conversation.

Example Flow:

Q1: "What is retrieval-augmented generation (RAG)?" A1: [Perplexity explains RAG basics]

Q2: "What are the main limitations of RAG?" A2: [Perplexity lists limitations]

Q3: "How do companies like OpenAI address these limitations?" A3: [Perplexity provides specific solutions]

Result: Comprehensive understanding in 3 questions vs reading 10 articles.
