In Sitecore Content Hub, you can use annotations to review content, provide feedback, and collaborate with others. You can add annotations to images and documents (such as PDFs, Word files, or Powerpoint files). When an asset has existing annotations, an indicator on the asset details page next to the Annotate icon displays the number of annotations.


You can also add annotations to video or audio files.
