Description

Writing by scanning is costly: each letter can take several seconds and several muscle activations. PredictIT offers the most likely words based on what has already been written, and gradually learns the personal vocabulary — proper names, places, recurring expressions — that no generic dictionary can contain.

The model runs entirely locally, with no connection. The personal dictionary is a readable, editable file that can be cleared at any moment: someone using the program must be able to know and decide what the system has memorised about them.

Who it is for

Anyone who writes by scanning and pays for every character in time and effort.
