Cases
One category, measured end to end.
Each case asks the questions people really ask in a category, in their own language, and records what ChatGPT and Claude answer. Every brand named and every link cited is counted. Each case publishes its questions, its method and its dataset, so the numbers can be checked. The shared method is on the method page.
