Some software alternatives to Microsoft Word are Apache OpenOffice, LibreOffice, FreeOffice, AbiWord, Scribus and Kingsoft Writer. An additional option is the NeoOffice available for Mac users as of 2015.
The LibreOffice software is extremely close to Microsoft Word when it comes to dependability. It is available for Windows, Mac and Linux, and it is similar to Microsoft Word in its looks and features. The Kingsoft Writer software is a clone of Microsoft Word and has even copied the Ribbon system of Microsoft Office. It goes one step further having additional features such as managing multiple documents using the same window. For more advance users wanting to create posters, flyers and newsletters, Scribus is a wonderful tool.
