The AI Visibility Index · Releases
Monthly category rankings, preserved as measured.
Each release freezes one shared set of repeated buyer-question answers. Companies in a category use the same denominator, rankings use the lower bound of a 95% confidence range, and old releases are never rewritten to match a newer result.
The first immutable release is being measured.
The live category index remains available. This archive starts when the first complete post-release monthly sample is published.
