TacticAI is an AI assistant for football tactics that has been evaluated through a comprehensive case study with expert human raters from Liverpool FC. The system includes predictive and generative components for corner kicks, including receiver prediction, shot prediction, and tactic recommendation. The case study validated the effectiveness of TacticAI's predictions and adjustments, as well as its ability to retrieve similar corners.

The raters found TacticAI's recommendations to be useful and constructive. The methodology can be applied to other set pieces and team sports. The next step is to integrate a natural language interface for interactive use of the assistant.
