Evernote

All your team’s work in one place. Whether you’re managing a project, capturing ideas from a brainstorm, or coordinating with a remote team, Evernote Business keeps everyone on the same page.

Starting from a simple note-taking app, Evernote has consistently added multiple features making it a serious contender in the content collaboration category. However, it works best only for small teams which are ideating, capturing notes and where searching capabilities across various forms of media is key.
