WordWise is a patented predictive text entry system for keypads on hand held devices.[1] It was developed by Eatoni Ergonomics with associated patents.[2] It has an efficient mode that uses LetterWise rather than multi-tap.[citation needed]

The WordWise system uses the sequence of pressed keys to predict the required word.[3]

Users may need to switch to LetterWise mode if unsuccessful in getting the desired word, so while it is word-based it still allows easy entry of rare names, urls etc.[citation needed]

It has been suggested WordWise is less sensitive to keypress errors than the competing T9 predictive text technology.[4]
