Using the Lernstift Pen is like having your teacher looking over your shoulder while you write. While that may sound irritating at first, the invention is really quite remarkable and offers invaluable assistance to people who are striving to improve their spelling, grammar and legibility.
Indeed, this compact and conveniently graspable stylus is just bursting with hi-tech features. It has calligraphy and orthography modes to monitor both the clarity of your cursive or handwriting and the correctness of your word formation and arrangement. Whether you're doodling on a piece of paper or even in the air, the Lernstift Pen follows your movements and vibrates when it detects an error. Upcoming versions of the clever device will be able to sync with computers, tablets and laptops to compile your statistics and copy your jotted text.
