Put simply, this is all about artificial intelligence. Bear in mind that SwiftKey isn't actually available on Windows Phone, so what is the rationale behind the deal?

Microsoft recently acquired the company for an impressive reported price tag of $250 million.

SwiftKey then offers predictions for words a user might want to type - with these predictions becoming stronger over time.

SwiftKey not only has a great 'swiping' offering that allows users to type without lifting their finger from the keyboard, but also does amazing things by analyzing a user's typing history (including their emails, social media missives, and text messages) and incrementally learning their usage patterns. It acquired Sunrise calendar, before adding its features to the Outlook app's calendar and shutting it down, with a similar fate befalling Wunderlist, which is being shutdown this month with Microsoft having taken its best features and adding it to its own To Do app.SwiftKey is an incredible little offering that replaces the native keyboard on an iOS or Android device and makes typing much better. In and around the time Microsoft acquired SwiftKey, the company was on something of a spending spree when it came to popular smartphone apps and services. It's safe to say, these are signals that the rebranding is underway. The change appears to have been first spotted by one of Android Police's readers. Likewise, 'Microsoft SwiftKey' is on the keyboard's space bar, and it's mentioned within the sidebar/settings menu of the app as well. While the Play Store listing keeps the traditional SwitKey Beta labelling, when the app is installed, its label on the home screen or app drawer is 'Microsoft Swiftkey' and then when its thumbnail is viewed in Android's recent apps window, the app naming is 'Microsoft SwiftKey Beta Keyboard'.
