    Doesn't mess up formatting like LibreOffice does.

    It's free and open source software. Compatible with most Microsoft Office documents. Doesn't track you at all.

    It does not require DotNet or Java to run. It runs natively on all WIN32 systems. That means it can be installed and run on Windows 95 right up to Windows 10 without any problems. It supports only open document formats, like the Rich Text format (*.RTF), that can be opened by any office suite on any operating system without any formatting errors. It is a very small download and install and also does not use any resources from the system.
