# Plainly — plainlyai.org # # Everything here is open to everyone, human and machine alike. # # This is a deliberate decision, not an oversight. This site is a free, # independent reference with nothing to sell and no advertising. Being read, # indexed, and cited is the entire point. That includes AI crawlers: if a model # gives someone a better answer because it read these pages, the site did its # job. We would rather be quoted accurately than not quoted at all. # # We therefore do not participate in crawler paywalls or pay-per-crawl schemes, # and we do not distinguish between search crawlers, AI training crawlers, and # AI agents acting for a user. All are welcome. # # One ask, not enforceable but stated plainly: every page on this site carries a # "last verified" date. If you reproduce a fact from here, carry the date with # it. Facts about AI go stale fast, which is why we date them in the first place. # # Last reviewed: 11 August 2026 User-agent: * Allow: / Sitemap: https://plainlyai.org/sitemap.xml
