AP StyleGuard is a powerful but simple solution that integrates with Microsoft Word and provides automated checking for AP style by applying defined structure and rules similar to Word’s spelling and grammar checking. AP StyleGuard ensures your writing is consistent and adheres to AP’s guidance, while freeing you up to focus on the content instead of the rules.

No matter what type of writing you do, AP StyleGuard helps you stay on top of current spelling, grammar, punctuation and usage guidelines from “the journalist’s bible.” StyleGuard includes current AP Stylebook guidance that is updated throughout the year to add new terms and changes based on news events, popular culture and our ever-evolving language.

StyleGuard operates on computers running Windows XP or later, and with Microsoft Office 2007 or later. A Mac-compatible version for Word only operates on Mac OS X 10.6 (Snow Leopard) and later, with Office for Mac 2011, Office 365 (desktop version) or Office 2016, and Safari 5.17 or above. No additional hardware or software is needed.

StyleGuard does not support Office Online, the web-only version of Office for tablets and smartphones. Internet connection is required for installation and activation, but is optional after initial activation. For more technical details, please see the Specifications section.


StyleGuard features include:

  • Automatic style-checking in Word as you type.
  • Proposed corrections are clearly highlighted in the document and StyleGuard displays the corresponding AP Stylebook rule, ensuring you understand why a correction is suggested.
  • A familiar interface that includes commands such as “Ignore All,” “Change,” “Change All” and “Add Comment.”
  • Users can turn style rules on or off when writing, and proof at any time.
  • Look up specific rules in your style collections — even when offline.
  • Additional real-time links, such as web references, to help you make writing or style choices not addressed by the AP.
