Talking about productivity tools, one can never forget Microsoft Office on desktop and Google Docs  on web. They’re competing product that invade each other turf (Google with Gears that allow Google Docs to go Offline, and Microsoft with it’s Office Web Apps) but surprisingly ‘close’ thanks to OffiSync.

OffiSync is an Office extension that ultimately allow you to save your Office documents to Google Docs & Google Sites, and at anytime open it back from within Microsoft Office. It is also collaboration tools (via Google Docs) that allow multiple editing with changes update done automatically,  but the later is not so relevant if you’re the only one who using it. But whatever it is, it is a must have application if you use both of them.

Here is how OffiSync works for you.

1. As Office extension, OffiSync is accessible from your Office application screen shot from Office 2007). No hassle of opening other application in order to upload/download the copy of your files. It is also compatible with Office 2010 Beta.

2. Save/Open Office Documents To/From Google Docs/Microsoft Office  just like they are inside your computers!

3. Sharing is caring, and here how you can show your generousness. To start collaboration, an invitation email to the participants must be send beforehand. Recipients who receive the invitation opened the document and start editing via Google Doc.

Other than that, you can email, copy link as well as open the document online.
