Microsoft Word for Windows will include a new predictive typing feature that automatically suggests new words to use as you are typing. Microsoft believes this new feature will help users type more quickly and reduce spelling and grammar errors. Microsoft’s machine learning model will better predict what you plan on typing based on your past work. The feature is not a revolutionary feature, and other applications and software have had it for a while. It is surprising that it took Microsoft this long to add the feature to one of their most popular Office programs.
