OffiSync wasa Microsoft Office 2003, 2007, and 2010 software extension that added to the core functionality of MS Word, Excel, and PowerPoint. OffiSync provided real-time co-authoring capabilities as well as the ability to save and manage files on the cloud through Google Apps and other collaboration platforms.

Once installed, users founda new toolbar in their Office applications letting them save their files on the cloud as if they were being saved locally. Users could also use Google search to find their stored documents and co-edit files with co-workers, seeing edits as they happen.
