Perplexity for humans: an editorial Twin Score review
Perplexity is a published product in this worldwide directory, not a crowdsourced star chart. Perplexity is an answer engine that retrieves the live web and cites sources in the same breath as the prose. That citation habit is why humans use it for research instead of a naked chat model. Collections, Spaces, and the mobile apps are polished.

We do not convert that number into a fake five-star average or invent a user count. Named author: the byline on this review is a staff editor who used public docs, the public app, and the public pricing page. If you need the machine view, read the twin page on Build Something Agents Want — same slug, different job.
