Perplexity

Perplexity is an AI search tool that answers questions and cites the sources it drew from, with links you can open and check.

That citation model is the point: it addresses the main weakness of asking a language model factual questions, since you can verify each claim against the page it came from rather than trusting the summary.

It works best for questions where current information matters — recent events, product comparisons, prices — where a model's training data alone would be out of date.
