"Microsoft's mission is to empower every person and every organization on the planet to achieve more. Our mission is to enhance interaction between people and technology. We think these are a perfect match, and we believe joining Microsoft is the right next stage in our journey."

Microsoft said that it will continue to offer the SwiftKey apps for Android and iOS, and that SwiftKey's technology will eventually be integrated with the Word Flow keyboard:

"In this cloud-first, mobile-first world, SwiftKey's technology aligns with our vision for more personal computing experiences that anticipate our needs versus responding to our commands, and directly supports our ambition to reinvent productivity by leveraging the intelligent cloud. SwiftKey estimates that its users have saved nearly 10 trillion keystrokes, across 100 languages, saving more than 100,000 years in combined typing time."

"We'll continue to develop SwiftKey's market-leading keyboard apps for Android and iOS as well as explore scenarios for the integration of the core technology across the breadth of our product and services portfolio. Moreover, SwiftKey's predictive technology aligns with Microsoft's investments and ambition to develop intelligent systems that can work more on the user's behalf and under their control."

"In the coming months, we'll have more to share about how we'll integrate SwiftKey technology with our Guinness World Record Word Flow technology for Windows."
