How to Use Perplexity AI: Complete Guide for 2026
Perplexity AI is the best AI search engine in 2026. This guide shows you exactly how to get the most out of it for research, work, and everyday questions.
Perplexity AI has become the go-to AI research tool for millions of users. Unlike ChatGPT, it cites every source, making it ideal for research and fact-checking. Here's how to use it effectively.
What Makes Perplexity Different
Perplexity searches the web in real-time and synthesizes results with citations. Every answer includes numbered sources you can verify. This makes it far more reliable than ChatGPT for factual questions.
Core Features
Regular Search
Just type your question. Perplexity returns a synthesized answer with sources. Better than Google for complex questions requiring synthesis across multiple sources.
Focus Modes
Use focus modes to restrict search to specific sources: "Academic" for scholarly papers, "YouTube" for video results, "Reddit" for community opinions, "News" for current events.
Follow-up Questions
Ask follow-up questions to dive deeper. Perplexity remembers context within a thread. Much faster than opening multiple Google tabs.
Collections
Save research threads to Collections for ongoing projects. Share collections with collaborators for team research.
