PhraseExpress bills itself as a "text expander for Windows," but that's too modest. In addition to its Swiftkey-esque autotext function and predictive typing chops, it also keeps a multiple-instance clipboard, checks spelling, and more—globally. Since it's not a plugin, you can use it anywhere on your Windows PC.
The software can help you can send the same email over and over—without having to retype (or even cut-and-paste). Or, save yourself the embarrassment and extra work of hunting down a broken HTML tag by storing the tags in PhraseExpress. Over time, PhraseExpress saves typing, pain, time, and—thoughtfully tracked within the program itself—money.
