Google Docs is a free online word processor, spreadsheet, presentation and form tool. It is similar to Microsoft Office, but the difference is that Google Docs is a web-based application. In Google Docs you store your files on Google’s servers and they can be accessed through your account only, unless you allow them to be public or shared. With a Google account you can create your word documents or spreadsheets in Google Docs. But if you don’t have a Google account you can still use a demo version of Google Docs — though I still encourage you to make one. It’s free!
To use a demo version of Google Docs you can go to docs.google.com/demo. This demo version allows users to try full-fledged versions of its word processor, spreadsheet, and drawing tool without a Google account. In the demo version you can choose whether to edit a Document, Spreadsheet or Drawing.
I personally like Google Docs. Beside it being free, it is accessible from anywhere as long as I’m connected to the internet. So I can store my work or data in Google Docs and edit it anywhere without the risk of losing or corrupting files. And Google Docs can export to Microsoft Office file types like doc, xls, or pdf.
