XT9

XT9 is a text predicting and correcting system for mobile devices with full keyboards rather than the 3x4 keypad on old phones.^[1] It was originally developed by Tegic Communications, now part of Nuance Communications.^[2] It was originally created for devices with styluses, but is now commonly used for touch screen devices. It is a successor to T9, a popular predictive text algorithm for mobile phones with only numeric pads. A small XT9 label on can be seen certain phones, mainly on HTC phones.^{[citation needed]}
