Embedded Dashboard with Generative QnA

It sounds like you're looking for a feature that allows users to ask questions specifically about the data in the currently active dashboard, rather than drawing answers from a broader topic. Fortunately, Amazon QuickSight has a feature that addresses this exact need called "Dashboard Q&A."

Dashboard Q&A, powered by Amazon Q in QuickSight, enables QuickSight Authors to add Data Q&A capabilities to their dashboards with just one click. This feature allows users to ask and answer questions about the data in their specific dashboard using natural language.

The key advantage of Dashboard Q&A is that it automatically extracts semantic information from the dashboards and uses it to enable Q&A over that specific data. This means that when a user asks a question, the system will provide answers based on the context of the current dashboard, rather than pulling information from a broader topic.

This feature enhances the existing Topic-based Q&A experiences by utilizing the semantics from dashboards to improve Q&A answers. It allows QuickSight Authors to deliver self-service access to customized data insights for the entire organization, focused on the data presented in each specific dashboard.

To implement this in your embedded dashboard setup, you would need to ensure that you're using the latest version of QuickSight that includes the Dashboard Q&A feature. Then, as a QuickSight Author, you can enable this feature for your dashboard. Once enabled, users interacting with your embedded dashboard will be able to ask questions and receive answers specifically about the data presented in that dashboard.

This approach should solve your requirement of having the source for questions come only from the active dashboard and not from a broader topic.
