Reviewers largely see Perplexity as a fast, clean AI search tool that often replaces Google for research, news, and everyday questions because it gives direct answers with source links and current web information. People especially value the minimal interface, mobile and voice use, and how quickly it summarizes many links into one response. Several say it helps with deep research, planning, and content work. The main caveat is trust: reviewers still report hallucinations, missing or weak citations, occasional wrong answers, ads, and weaker performance in long threads or some deep-search cases.
