Dropbox Paper is now available to all as an open beta

Ten months after Dropbox first unveiled Paper, the collaborative writing tool entered open beta on Wednesday and is getting mobile versions for iOS and Android.

Paper allows teams to work on documents together in the cloud. It makes it easy to add text, images, and embedded videos from YouTube, Google, or Dropbox itself. Users can also add programming code, which gets formatted automatically. And they can create to-do lists and assign tasks on those lists using the @ symbol.

Since its debut in private beta, Paper has been used to create more than a million documents for tasks like brainstorming ideas and capturing meeting notes, Dropbox said. Based on lessons learned along the way, Dropbox has improved the software with better tables and image galleries, more powerful search, and notifications via desktop and mobile.

The new apps for Android and iOS, meanwhile, let users get project updates, make edits, and respond to feedback from their mobile devices.
