Limitations

  • This is one response per prompt/provider pair in each run; model output can vary between runs.
  • The fixed 16-prompt Legal AI category does not estimate general market share or brand awareness.
  • Presence share and citation share are relative only to the reviewed 12-brand universe; untracked brands are excluded from those denominators.
  • OpenAI, Anthropic, and Google are both evaluated brands and configured model providers; no self-provider bias correction is applied.

                      A value of 1.0 means the complete frozen cohort passed the deterministic extraction and publication gates; it is not a statistical confidence interval.

                      Citation Share Denominator

                      Distinct answer-level HTTP(S) citation URLs whose URL-derived hostname matches any reviewed brand domain.

                      Presence Share Denominator

                      The sum of reviewed-brand answer-presences. One answer may contribute presence to multiple brands.

                      Mention Coverage Denominator

                      48 answers: all 16 prompts multiplied by 3 configured providers.

                      Provider Mention Coverage Denominator

                      16 prompts for the named configured model API provider.

                      Provider Recommendation Presence Denominator

                      Recommendation Semantics

                      Presence means mentioned or cited in an answer to a recommendation-intent prompt. It does not claim positive recommendation, endorsement, or sentiment.
