New AP tools for better proofing in your computer's web browser

First, to make sure you're choosing the right words, there's Stylebook & Webster's New World Online. This add-on to AP Stylebook Online integrates about 185,000 definitions from Webster's New World College Dictionary (the Stylebook's primary dictionary). Subscribers can do a single search to get clearly labeled results from both the AP Stylebook and Webster's. Where those definitions differ, users see both entries so they can compare and choose.
Per-user subscriptions start at $35 for one year for a single user, or $21 for users employed by AP member organizations. (That's above the base cost to subscribe to AP Stylebook online, which start at $26/year for AP Stylebook Online.) If you're not a Stylebook subscriber, you can sign up to receive an e-mail update when this service is out of beta and generally available for purchase.
Next, Lingofy is a web browser plugin browser plug-in that provides automated AP style checking in web-based content entry forms (such as for WordPress, Facebook, or Twitter). Lingofy integrates directly with Mozilla Firefox, Microsoft's Internet Explorer and Google Chrome.
You can customize your Lingofy dictionary, and also provide a enter and maintain your own terms (such as proper names, place names, and your own stylistic pet peeves) in a personal dictionary. You can also designate "warning words" to be flagged, such as vulgarities, clichés and legalities.
Lingofy subscriptions start at $79.99 for one year, or $69.99 for employees of AP member organizations. So far the beta test version is available only for Windows users (Mac due our later in November).
It doesn't appear that Lingofy is available for mobile users; and since it's a browser plugin, it's unlikely that it would integrate with mobile apps such as those for Twitter, Wordpress, Instagram, or Facebook. The lack of mobile usability is a significant weakness in this offering, since the inherent challenges of mobile typing and editing are especially likely to yield embarrassing typos and style errors.
