Today, TeamSlide Pro only indexes slides on your computer. If you have presentations in Dropbox or Box that are sync’d with your hard drive, these can be selected to be searchable. However, content that is only in the cloud is not accessible by TeamSlide.
We are actively working on extending TeamSlide Pro to search cloud repositories like Dropbox, Box, OneDrive, and Google Drive. Note that TeamSlide Business, our sister product that let’s teams of users search a shared repository, does allow for integration with cloud content.
