StyleGuard | Lingofy


AP StyleGuard is a powerful yet easy-to-use solution that integrates with Microsoft Word and Outlook to provide automatic AP style checking. Using defined structure and rules similar to Word’s spelling and grammar checking, AP StyleGuard helps ensure the consistency of your writing.

AP’s automated style-checking tools speed up the editing process by reducing the need to manually refer to the AP Stylebook. StyleGuard offers recommendations on datelines, abbreviations and acronyms, among many other common style needs, along with 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 must-have reference for writers and editors.

AP Lingofy

Now you can proof your content based on AP style when you’re working in WordPress, Twitter or other web-based tools, including your CMS. AP Lingofy is the ultimate on-the-go editing aid for journalists, corporate publishers and PR and marketing professionals who create content online.

Lingofy checks your writing against the AP Stylebook with Webster’s New World College Dictionary, Fifth Edition, providing advanced proofing assistance for both spelling and style. AP Lingofy includes almost 5,000 AP Stylebook entries to address terminology in politics, economics, law, medicine, the internet and popular culture. With Webster’s New World as a foundation, it is able to manage spelling and usage from AP’s primary dictionary. Lingofy also allows you to add your own custom style rules and local proper names with proofing rules.

The internet has changed everything. Language is expanding faster than ever, and so are embarrassing online errors that can sabotage your message and your business. Basic spell checking just isn’t enough — Lingofy was developed to manage the challenges that modern-day content creators face.

AP StyleGuard features include:

  • Your documents are checked automatically in Microsoft Word or Outlook as you type.
  • Each proposed correction is clearly highlighted in the document and shows you the corresponding AP Stylebook rule, so you always know why something was corrected.
  • Easy-to-understand features are similar to other proofing tools, including Ignore All, Change, Change All and Add Comment.
  • Users can easily install multiple style guides from Equiom, with the ability to turn on/off specific guides and search for specific rules.
  • Additional calculators, tables and real-time data links, such as web references, help make your writing faster and more accurate.

AP Lingofy features include:

  • Flag spelling, usage and AP style errors and accept, reject or alter Lingofy’s suggested fixes.
  • Checks content in phrases, not individual words, which allows Lingofy to know it should change “Bombay” to “Mumbai,” but leave “Bombay gin” alone.
  • Create, edit, share and import custom style entries to manage regional terms (“firefly” or “lightning bug”), local proper nouns (“E.P. ‘Tom’ Sawyer State Park”) or common typos and frequent misspellings (“mispellings”).
  • Set certain words or phrases as warnings to remind writers and editors to double-check context, avoid cliches or vulgarities, or spike them outside of direct quotes: “pubic” is appropriate in medical copy but probably not in a story about local government.
  • Multiple workflow options that allow you to share custom entries with other Lingofy users, setting permissions and proofing guidelines to match your needs.
  • Built-in Check Text feature for testing new entries or proofing copy written offline.
  • Proofing statistics: Track which words are flagged most, past proofing sessions and more.
