AP StyleGuard is a powerful yet easy solution that integrates with Microsoft Word and provides automatic checking of your documents for AP style. Using defined structure and rules similar to Word’s spelling and grammar checking, AP StyleGuard helps ensure the consistency of your writing style. It saves you the time of manually referring to the AP Stylebook and offers recommendations on items you might not have realized are covered by AP style.

No matter what type of writing you do, you can rest assured that AP StyleGuard helps you stay on top of all of the current spelling, grammar, punctuation and usage guidelines from the journalist’s bible.

StyleGuard includes current AP Stylebook guidance, with rules updated throughout the year to keep your writing covered by new additions and changes responding to news events and the evolution of the language.
