# 9. Commenting and collaboration

Power BI provides a native, true, out-of-the-box commenting capability. It supports report-level and visual-level commenting, including @mentions and collaborative conversations. However, data-level commenting is not possible.  

Data-level commentary is very common in real-life scenarios. Inforiver delivers user-friendly notes and annotations to Power BI users using a no-code user experience. 

Notes Inforiver are dynamic – in that, they are tied to a specific data point, row, or measure. Filtering the report makes the note appear at the appropriate location, as it is always tied to the data.
