“Answers with footnotes. Loads without them.”

Pica's take. Perplexity is quick, tidy, and cites its sources, which already puts it ahead of half the internet. The locks are decent, the guest list is short, and it lives on Cloudflare. Young, but well read.

How we grade. Four checks, weighted equally: speed timed by our own browser, a security look from the outside, public reputation signals, and the network the site lives on. A look from the outside is not a server audit.
