Perplexity has won over researchers and the source-conscious by treating citations as the default, not an afterthought — people trust answers they can click through to verify, and the live-search grounding keeps it current. The limits users note are that it is built for answers rather than long creative or coding sessions, and the best models sit behind Pro. For sourced research, sentiment is strongly positive.
Perplexity is built by Perplexity AI, a San Francisco company founded in 2022 that pioneered the cited AI answer engine.
