How was this page made?

We publish this page and sell in this category. Every claim about another company comes from that company’s own public pages, or a paper or partner report it cites, read on October 27, 2026, and each is listed below. Where a company publishes nothing on a point, the page says so; that does not mean it cannot do it.

Each company measures accuracy its own way, on its own tests, so the figures are shown side by side but never ranked as one league table. We did not trial the other products. Our own figures are the ones on our pricing and accuracy pages. Something out of date? Tell us through the contact page and we will correct it.
