In Short: Microsoft has just announced that SwiftKey for Android received Microsoft Translator integration. This is not actually surprising as Microsoft has been testing this feature inside of SwiftKey for a while now via its beta channel, and it's now available in the stable channel as well. This will make translation really simple, as you'll be able to do everything directly from the keyboard, so just in case you don't use Gboard and Google Translate in combination with it, this is a really solid alternative. You won't even have to copy and paste text in order to translate it, SwiftKey cuts that step and lets you translate content faster. So, all you have to do is click the Microsoft Translate option on the toolbar, write whatever you want (after selecting languages), and the app will automatically translate whatever you write on the toolbar and put it on the website, document or wherever you activated the keyboard.
Background: Microsoft had announced a while back that the feature is in testing with SwiftKey Beta, and that version was actually quite stable, and we did not see any problems with Microsoft Translate, so this update is definitely not a surprise. SwiftKey has been around for a long time at this point, but Microsoft was not always its owner, the company actually acquired it some time ago and added to its portfolio. SwiftKey is one of the most popular keyboard apps for Android at the moment, it's holding a 4.5-star rating in the Play Store, while it has been downloaded way over 100 million times.
Impact: Microsoft Translate actually supports over 60 languages, so it may end up being useful for those of you who use SwiftKey. Microsoft says that translations will work even better if you have a separate Microsoft Translator application installed, as it will allow you to translate content offline. Microsoft Translator integration has been added via v184.108.40.206 of SwiftKey, in case you're wondering, and that update is rolling out via the Play Store as we speak, though it's a staged rollout, of course.
