The obvious choice for company level wiki/document repository.

One of the key benefits of Confluence is that it's incredibly easy to use. Any user of any skill level can jump in and at least use its basic functionality without much guidance. However, it still provides advanced capabilities, such as integrating Jira tickets and document /space permissions.

Well suited for highly accessible, large-scale documentation repository. Particularly in cases where transparency is particularly valuable. e.g., system requirements, how-to's, meeting notes, collaborative documents, release notes, etc. It is less appropriate for richer interactions such as workshops, where, for example, Miro might be a better option, or formal documentation, where Word or Docs would be more appropriate.
