Perplexity

Perplexity is an AI-native search engine that combines large language models with real-time web search to provide direct answers to questions, complete with citations to source material.

Unlike traditional search engines that return a list of links, Perplexity synthesizes information from multiple sources to provide comprehensive answers. Each answer includes inline citations, allowing users to verify information and dive deeper into sources.

The platform offers both a free tier and a Pro subscription with additional features like unlimited queries, file uploads, and access to multiple AI models (GPT-4, Claude, etc.).

Perplexity is particularly valuable for research tasks, fact-checking, and situations where you need quick, reliable answers with transparent sourcing. It's become a favorite tool among researchers, journalists, and knowledge workers.
