Perplexity

Perplexity is an AI-powered answer engine that combines live web search with large language models. Instead of a list of links, you get a direct answer with inline citations you can verify.

It shines for research: follow-up questions keep context, Focus modes restrict sources to academic papers or specific sites, and Spaces organize ongoing investigations. Pro search runs deeper multi-step research for harder questions.

The free plan covers everyday lookups, while Pro unlocks more Pro searches, model choice, and file uploads. For anyone who treats search as a starting point for understanding, Perplexity is a serious Google alternative.
