I purchased Antidote to the launch by my office a weekly newsletter that I could not afford to let spelling and grammar errors. Objective perfectly successful: Antidote not only identifies many errors that Word leaves out, but, in addition, to give each of them a clear explanation allowing to understand nature. Antidote will, in addition, much further than the analysis of the spelling and grammar: typographical errors, repetitions, pleonasms, etc. are highlighted. And what about its stunning dictionaries except that it is a treat to see them? Integration with software that I use constantly (Word, Outlook, PowerPoint) is, in turn, perfect. Congratulations.
