Reply to Annotations in Our JavaScript PDF Viewer

Annotation replies allow you to create a thread of comments in a PDF document. If you use Server-Backed as your deployment option, PSPDFKit for Web will display any Instant Comments you create as a threaded conversation.

A thread of Instant Comments

In addition, if you open a document where Instant Comments were created by any of the PSPDFKit SDKs, these comments will be displayed in a thread too.

Note that to view and create Instant Comments, you must enable Instant when initializing PSPDFKit for Web:

	instant: true,

Annotation replies created by other PDF software aren’t yet supported by PSPDFKit for Web, and they’ll be displayed as individual note annotations.
