Quick Insights is one of the most analytically advanced features in Power BI as it enables sophisticated machine learning algorithms to be executed against datasets or specific subsets of those datasets. The results of these computations automatically generate highly formatted Power BI visuals which can be integrated into reports as though they were created from scratch. Quick Insights is only generally available in the Power BI service for import mode datasets and dashboard tiles reflecting those datasets. However, the essential capabilities of Quick Insights are also now available in preview for Power BI Desktop.

In the following image, Quick Insights has been executed against the AdWorks Enterprise dataset in the Power BI service: 

To execute Quick Insights against an entire dataset, see the Get quick insights option under the Actions ellipsis menu in the Power BI service. Once the insights have been generated, a View insights menu option replaces the Get quick insights option. The visuals generated from the insights, such as the clustered bar chart on the left, advise of the algorithm used (for example, outlier, cluster, and correlation). Most importantly, the visuals can be pinned to dashboards and are displayed without the supporting text like normal dashboard tiles. In Power BI Desktop, Quick Insights are currently limited to specific data points represented by report visuals.
