Dropbox Paper

Dropbox Paper is very well suited in a corporate environment where both the file management and the document editing and collaboration must be easy to use but without the risks of less secure and reliable platforms (including some that are available online and are 100% free) as companies like mine have a very restrict and specific need to control access of users and avoid data from leaking outside the limits of the specific project Team.
As for scenarios where it is less suited, I can only think of the fact that it lacks a full Project managing suit where the project team could move documents around steps and have a visual platform for project managing. While one can say it is a bit out of scope of the tool offer, having such capabilities would feel very natural...

To be honest, there is very little reason to switch to Dropbox Paper from other tools you may already be using, such as Google Docs, because of their lack of differentiation. On the other hand, if you don’t currently use a collaboration tool, and you’re already paying for Dropbox, then Paper is worth considering.

DropBox Paper is perfect for groups or teams that are needing to create and collaborate together but can't all be together in the same office or all on the same call or zoom meeting. It allows everyone to create together in real time and then also work on a project together and check off items as they are completed. It makes it super helpful when you can transfer other docs into your team "file" so that everyone has a visual of what is begin discussed or has that doc to use for their work in the future at their own time and pace.

Dropbox Paper is suited for creating very simple documents, where you are collaborating with other users. It is particularly useful in a work environment that primarily uses Dropbox as a storage and file management solution. If you need to create documents where you need more enhanced formatting features, you would need to use Google Docs, or Microsoft Word.

When collaborating with a team on content creation with the purpose of bringing multiple inputs in a nonstructured or nonfixed media type, this is a great choice because of its diversity of content and collaboration tools, however, if you are looking to have high flexibility in a particular content creation stream, for example, sophisticated text editing or presentation, there are a lot of strong competitors out there.
