A free writing app from Pearson now plugs into Microsoft Word to make its feature set available to students as they're working on assignments. Pearson Writer is available as a standalone application for computers and laptops and as an app for Apple iOS and Google Android. Now similar functionality is available as an add-in that shows up in a side panel in Word 2013 and 2016 on the PC, Word 2016 on the Mac and Microsoft Office 365.
