OffiSyncis a plugin for Microsoft Office that serves as a bridge between Office and Google Docs. When it first launched, the app’s primary feature was to save Office documents to your Google account. It’s since integrated Google Image Serach into Office, and support for Google Sites. And today it’s getting another major upgrade: you’ll now be able to sync changes between the same document being edited simultaneously by multiple users using any modern version of Office and/or Google Docs.
That’s a big deal, because Microsoft has been heavily promoting real-time collaboration as one of the key features of Office 2010. With OffiSync, you wouldn’t necessarily need 2010 — you’d be able to coauthor a document using Microsoft 2003 and 2007 as well, and you won’t need SharePoint, either. The application allows you to do Office-to-Office collaboration, and you can also have users editing the same document from Google Docs’ online interface. Changes aren’t synced as you type in each character, but rather each time you hit the ’save’ button.
The new version of OffiSync adds support for the ‘any file upload‘ feature that Google Docs added in January. It also has better integration with Google Sites (it will automatically pull in your Google Sites file hierarchy within Office, and allows you to create a file on Sites from Office as well).
While OffiSync offers a free version of its product, most of these new upgrades (including coauthoring) are for premium users only. Premium seats cost $12 a year, or there’s an option for a $30 one-time fee. And, sorry Mac users — OffiSync is still only available for Windows.
OffiSync has been doing quite well lately — it’s currently the top rated app on the recently-launched Google Apps Marketplace, and has the third most installs on the Marketplace overall. CEO Oudi Antebi says that OffiSync now has over 300,000 users The company hasn’t disclosed its funding, but says that it closed a Series A round of over $1 million.
