Mention someone

Mention a colleague anywhere in your Paper doc by typing @ (the at symbol) and then their name.

If the person you mention has a Dropbox account, their name is shortened to reflect the name on their account.

If you click a hyperlinked name, a dropdown appears. You can then search every shared doc that person created.

Leave comments

  1. Highlight a line of text to bring up the formatting toolbar.

You can @ (at) mention a colleague in your comment to send a notification.

See the author

Attribution shows you who wrote a section of a document. The name of the person who wrote a part of a document is shown beside the text. This happens even if you copy-and-paste from one Paper doc to another.

Note: The name of the person next to a piece of text might not be the original writer. If the content is copy-pasted into Paper, the attributor may change. Content copied from external sources, or pasted without formatting, is attributed to the person who pastes it. Content copied from another Paper doc is attributed to the original contributor.

FAQs about collaborating across new Paper and old Paper releases

What happens if a new Paper user shares files with users on old Paper, and vice versa?

If a new Paper user gets shared an old Paper doc or folder, they'll have access to view and edit the content, but they won't have the ability to view the .paper file in Dropbox. The content will continue to live in the document owners Paper folder until migrated to Dropbox.


If a Dropbox or Paper folder is shared, both parties will be able to view the contents. The person on the old Paper release will be the only one able to add to the Paper folder. The person on the new Paper release will be the only one to add a Paper doc to the Dropbox folder.

What happens if an old Paper user joins a team with the new Paper release?

If an old Paper user joins a new Paper release team their team account becomes a new Paper release account. They won't have access Paper Home from the team account. A paired personal account is unaffected.

How can I find my Paper docs?

  • Search the Paper docs by name. 
  • Paper mobile will show all of the old and new Paper docs together. 
  • For new .paper docs shared with you, look on the Shared page.
  • Recently accessed Paper docs can be found on Recents page.
    • You can access this from the All files page on Click the Recents tab.
  • Once you find your Paper docs, you can star or bookmark them to find them easily from the homepage.
