Proof, not promises
We tested our engine against frontier models.
Ask even the smartest AI to describe a website and it guesses: a price here, a social link there, a fact that was never on the page. Our engine doesn't guess. It reads your live site, verifies every value, and ships only what's actually there. And we don't stop at correctness. SchemaX measures what machine legibility earns you: AI-referred visits by surface, agent activity, and the inquiries that follow. That way 'agent-ready' is a number on your dashboard, not a promise.

Grounding isn't a model property. It's an engine property.
