It allows users to inspect prompts and answers, compare competitors, segment by market, language, and persona, and create client-ready reports. The platform is designed for agencies managing local, national, and multilingual accounts, enabling them to see who AI assistants recommend, why competitors win, and which content, citation, and entity fixes can improve visibility.

It provides targeted preference audits to show whether AI recommends a client or a competitor for specific contexts. Additionally, it offers query-level testing across major AI models while preserving important variables.
