Google has rolled out an update to its own keyboard app on Android in the Play Store, the update is significant in that it now comes with personalized word suggestion synced from the cloud from other Google services. Not to be confused with the "personal dictionary", this adds another scope to the experience by syncing personal auto suggested (saved) words from Chrome browser, Gmail, Calendar, Google+, and Drive. After applying the update, the user is given a prominent warning of the new feature, perhaps saving embarrassment for synced unsavory words used in the other Google products, and also because it is enabled by default. This update will also be applied OTA for KitKat 4.4 users, the keyboard also features 4.4 only options but can be installed on Android 4.0 or later, full description of the update is below.

With amazing word recognition and next-word prediction, Google Keyboard helps you type faster and more accurately on all your Android devices.
