# Create a dataset

**Note**  
The SiteWise Monitor feature is no longer available to new customers. Existing customers can continue to use the service as normal. For more information, see [SiteWise Monitor availability change](https://docs.amazonaws.cn/iot-sitewise/latest/appguide/iotsitewise-monitor-availability-change.html).

**Note**  
 The Amazon IoT SiteWise Assistant must use a dataset with an [Amazon Kendra](https://docs.amazonaws.cn/kendra/latest/dg/what-is-kendra.html) index for enterprise level knowledge and guidance. If you do not have a Amazon Kendra index, see [Creating an index](https://docs.amazonaws.cn/kendra/latest/dg/create-index.html) to create one. Adding a [dataset](concept-overview.md#concept-dataset) improves the quality of the Assistant's response, and minimizes hallucinations.
