The following code snippet handles the QueryIAIExtensionsContainer event to use the WilliamShakespeareStyleExtension only when requests are initiated by the richEditControl:

using DevExpress.AIIntegration;

var localContainer = new AIExtensionsContainerLocal(AIExtensionsContainerDesktop.Default);
localContainer.Register<ChangeStyleRequest, WilliamShakespeareStyleExtension>();

AIExtensionsContainerDesktop.QueryIAIExtensionsContainer += (s, e) => {
    if (e.Source == richEditControl)
        e.Container = localContainer;
};

// ...
// A custom extension based on the DevExpress ChangeStyleExtension.
// The example overrides the GetSystemPrompt method to customize the pre-built prompt.
public class WilliamShakespeareStyleExtension : ChangeStyleExtension {
    public WilliamShakespeareStyleExtension(IServiceProvider serviceProvider) : base(serviceProvider) { }
    protected override string GetSystemPrompt(ChangeStyleRequest request) {
            return "Rewrite this text in the William Shakespeare style.";
    }
}
