+This demo incorporates AI-powered insights into DevExtreme [DataGrid](/Documentation/Guide/UI_Components/DataGrid/Overview/)'s [master-detail interface](/Documentation/Guide/UI_Components/DataGrid/Master-Detail_Interface/), extending the component's built-in AI data exploration capabilities. A custom AI-driven UI is configured that allows you to analyze individual record data using natural language. To access this UI and generate data, click the AI icon on the left side of a row and enter a prompt.
+
+<!--split-->
+This demo complements the DataGrid's built-in [AI columns](/Demos/WidgetsGallery/Demo/DataGrid/AIColumns/) capability, which generates data for every row in the component. The AI-powered detail view augments data only within specific rows. This significantly reduces AI token consumption and enhances data generation performance in usage scenarios that do not require generated data for every row.
+
+To display the AI-powered detail view, this demo defines the DataGrid's [master-detail template](/Documentation/ApiReference/UI_Components/dxDataGrid/Configuration/masterDetail/#template). The template uses DevExtreme [TextBox](/Documentation/Guide/UI_Components/TextBox/Overview/) and [Button](/Documentation/Guide/UI_Components/Button/Overview/) components to allow you to enter and submit prompts. This example also configures a DevExtreme [ButtonGroup](/Documentation/Guide/UI_Components/ButtonGroup/Getting_Started_with_ButtonGroup/) component as prompt suggestions, mirroring the DevExtreme Chat's [Suggestions](/Demos/WidgetsGallery/Demo/Chat/PromptSuggestions/) capability. After you submit a prompt, generated responses appear in a DevExtreme [TextArea](/Documentation/Guide/UI_Components/TextArea/Getting_Started_with_TextArea/) component.

-We plan to integrate AI-driven data exploration into the [DataGrid](https://js.devexpress.com/Documentation/Guide/UI_Components/DataGrid/Overview/)'s master-detail scenario. This new functionality allows users to analyze individual record data using natural language.

-In v25.2, we released the [AI column capability](https://www.devexpress.com/subscriptions/new-2025-2.xml#js-grids-ai-columns) for DataGrid. This feature introduced the ability to extend component data using an AI prompt. However, certain usage scenarios do not require generated data for every row. Instead, users may need on-demand data generation for specific rows. Our new AI detail scenario will offer this capability, which can significantly reduce AI token consumption and enhance data generation performance.

-Our new AI master-detail feature will also display generated content in a format better suited to longer, more in-depth insights. The capability will include a prompt-driven data analysis UI within DataGrid master-detail interfaces, spanning the full width of the component. 
 
-Within the detail row, users will be able to ask questions about the active record and receive AI-generated insights. The AI assistant will be able to summarize record data, clarify complex values, highlight notable patterns, and obtain contextual information specific to the active record.
