Explains how to add a note to selected text within a document using the text selection and annotation tools in the Document Viewer.


The Opus 2 Document Viewer allows users to annotate documents by attaching notes directly to selected text. This is useful for adding commentary, highlighting important passages, or capturing issues during document review.


Text‑based notes are created by selecting text within a document and inserting a note linked specifically to that selection. Notes can be shared with all project users or restricted to specific users or groups, depending on visibility requirements.


If AI features are enabled, additional functionality such as AI Autofill may be available when creating text‑based annotations.

  1. Open the required document in the Document Viewer.
    (See related guidance for opening a document if required.)
  2. Click the Select Text button in the document toolbar.
