How we got these numbers
We read Promptmonitor's own pricing page on Oct 8, 2026 and kept a dated screenshot. Nothing here comes from other review sites, which often still quote plans vendors have dropped. A script re-reads the page every morning; confirmed changes go in the price change log.
We haven't yet run Promptmonitor through our hands-on accuracy test. When we do, the results will go on this page. How we test.
No vendor paid for this page, and we earn nothing if you click through to Promptmonitor.
