It’s alive! SwiftKey 3 is a $3.99 replacement keyboard for Android that learns from you the more you use it, predicting which word you’re going to type next. The app scans your emails, text messages and social media updates to learn your lingo and turn would-be errors into coherent missives. It’s shockingly accurate, making for a creepy-fast typing experience. You can even type in multiple languages at once.
