Reviewers mostly see Perplexity as a fast, practical research tool that often replaces traditional search: they praise its cited answers, clean interface, strong mobile and voice experience, and ability to summarize current information from many sources without opening dozens of tabs. People use it for quick learning, deep research, news, planning, and content fact-finding. The main caveat is trust: several reviewers still report hallucinations, missing or mismatched citations, weaker performance in long threads, and some disappointment with newer ads or browser sync.
