MojoKid writes: SwiftKey has been one of the more popular predictive keyboard offerings in the mobile space since it was first released in beta form on the Android market back in 2010. What made SwiftKey so appealing was its intelligent predictive texting technology. SwiftKey isn't a simple keyboard replacement. Rather, the software uses a combination of artificial intelligence technologies that give it the ability to learn usage patterns and predict the next word the user most likely intends to type. SwiftKey refines its predictions, learning over time by analyzing data from SMS, Facebook, and Twitter messages, then offering predictions based on the text being entered at the time. It is estimated that SwiftKey is installed on upwards of 500 million mobile devices. According to reports, Microsoft is apparently buying the UK-based company for a cool $250 Million. What Microsoft intends to do with SwiftKey is not clear just yet, but the company has been purchasing mobile apps at a good clip as of late.
