Reviewers mostly see Perplexity as a fast, clean research tool that often replaces traditional search for everyday questions, current information, and deeper topic exploration. The most repeated strength is sourced answers: people like getting summaries with links they can verify, plus an interface that feels simple on desktop and mobile. Heavy users also praise features like voice, sharing, project spaces, and broad search coverage. The main caveat is reliability: reviewers still report hallucinations, weak citations, lost context in long threads, occasional glitches, and some dislike ads.
