Perplexity

What is Perplexity?

Perplexity is an AI search engine that searches the web and gives direct answers — no list of links, but a curated answer with clear source references. It positions itself as a new type of search engine, suitable for answering specific questions, doing research and comparing information from multiple sources.

How does Perplexity work?

Perplexity combines real-time web searching with a large language model. When a user asks a question, Perplexity performs multiple searches, analyzes the found content and synthesizes it into a coherent answer. The sources are transparently listed so users can verify the information.

Perplexity also offers a Follow-up feature: after an answer, follow-up questions can be asked that retain the context of the original answer. This creates a conversational search experience.

Core features

• Real-time web search — always up-to-date information
• Source references — transparent about which sources were used
• Conversational — ask follow-up questions in the same context
• Deep Research — comprehensive research via multiple sources (Pro)
• Multiple models — GPT-4o, Claude, Sonar and more available
• Spaces — save organized research projects

Comparison with Google

Perplexity is better for specific factual questions where you want a direct answer. Google is better for discovering diverse sources, finding specific websites and local searches. For in-depth research, Perplexity Pro's Deep Research feature is particularly strong.

Advantages

• Direct answer without having to click through links
• Transparent source attribution
• Free tier available

Disadvantages

• Less strong for local or specific website features
• AI can make mistakes when summarizing sources

Pricing
