Gamekin is a Windows-first AI companion that understands the game or app window you select and answers by voice without making you tab out. Ask with Alt+V, continue naturally in Conversation mode, or enable Adaptive Coach for brief, context-aware debriefs. It runs inside Xbox Game Bar, brings current sources into its overlay, keeps history and per-game progress, and works across capturable games and Windows apps—without DLL injection, memory reading, input automation, or stored audio/images.
