Perplexity AI has grown from a research experiment to one of the most-used AI tools in 2026. Its premise is simple: AI search that cites its sources. But the execution is impressive enough that it's replacing Google for millions of users. Here's the full review.
Perplexity is an AI-powered search engine that gives direct, synthesized answers to any question — with citations linking to the sources it used. Unlike Google, which shows you a list of pages to visit, Perplexity reads those pages and gives you the answer. Unlike ChatGPT, Perplexity searches the live web for every query.
