Limitations
- This is one daily response per prompt/provider pair; 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.
