GroupDocs Annotation is a web-based app that allows users to annotate PDF, Word, Excel and PowerPoint documents online, from a web-browser. With this app, you and your colleagues and partners can review and annotate a document simultaneously, in real time. We’re constantly working to improve the app’s interface and would like to introduce a new set of features we’ve recently designed and implemented.

Add and Manage NotesGroupDocs Annotation lets you add notes throughout a document which show up as numbered markers. Hover the cursor over a marker to see the comment or click a marker sign on the right-hand side to go straight to the comment.

Familiar Editing ToolsWe’ve added a set of new annotation tools and improved the existing ones. Now it is even easier to add notes to a document, wherever you want. With the new Area Notes and Polyline tools, you can easily highlight an area in a document. You may also find useful the new options that allows you to strike out text and add new text sections.
