In the past, we have BrowserShots to verify our websites in several browsers. It is very useful for web developers who wanted to have an unified design in all browsers.
What i want to share right now is another service, but for different purpose. We are not talking about web pages, but documents. Yes, we have quite several alternatives to Microsoft Office which is still considered a de facto standard in many plances, such as OpenOffice.org, AbiWord, KOffice, and many more.
If you want to compare your documents when viewed in other applications, you don't have to install them in your computers. Just go to OfficeShots and upload your documents there. The site will compare your documents. Pretty cool isn't?
