Collaboration means discussion, and Instant Comments is the easiest way to discuss PDF documents in real time.
Built on top of our PSPDFKit Instant technology stack, Instant Comments is the drop-in solution for adding real-time document discussions to PSPDFKit for iOS.
Only updates to comments are propagated to devices, and conflicts are resolved server-side.
Easy-to-follow linear comment threads that are updated in real time.
Updates are saved locally and uploaded the next time the device is online.
Faster and simpler collaboration workflows are what PSPDFKit Instant was created for, and Instant Comments is the ideal tool for document-centric communication.
Give your users the ability to place a comment anywhere on the page or attached to a text highlight annotation.
Instant Comments uses an easy-to-follow thread view with a familiar styling.
Instant comments are stored as PDF replies on export. This means that any PDF reader that supports annotation replies will also be able to show Instant Comments.
PSPDFKit Instant deploys within your existing infrastructure — you retain complete control over your data.
Using industry-standard JWTs allows for easy integration with your existing authentication system.
Sync document edits, text highlights, and annotations across iOS, Android, and web devices in real time.
