Proofy is not software that purports to proofread text itself: it's not a Grammarly or WhiteSmoke knockoff. Rather, it is support software for proofreaders. They use it to track customers, projects, number of words proofed, income, and other data over time.

Proofy is the Windows graphical-user interface program that grew out of the initial command-line app 'prt' used by the programmer. The developer of "Proofy" runs the William Miller Services page on Facebook. If you want to visit, you can get there by clicking on the Facebook icon in this About dialog, or on the image below. Or, you can use the app's menu system.

If you click my picture in the top-left of this About form, the program will copy my email address to your Windows clipboard.
