The Crane Index™ Leaderboard

The most AI‑readable sites, by industry.

The top of every published Crane Index™ benchmark, in one document. Each site is given the same three deterministic reads, whether AI search can find and cite it, whether an agent can act on it, and whether a machine can confirm who it is. This is the monthly roll of honour: the highest scores in each list, every company named, every score verifiable live. It is re-run on the first of each month, so the movement becomes public record.
