The accuracy of predictive text depends on what writing assistant tool is being used, and in what situation. In data comparing Typewise text prediction and autocorrect vs Google Gboard vs Apple Keyboard,
Typewise's AI outperformed both, saving users a higher percentage of keystrokes.
As the current speed of text input occurs at only around 10% of the speed of human thought, there is still considerable ground to be gained in terms of writing assistant AI. As the sophistication of text prection tools increases, the number of keystrokes required will decrease, therefore reducing typing time and closing the gap between the speed of thought and the speed of typing.
