It looks trivial at first glance, but it is technically novel (patent pending).
It eliminates tedious keyboard word entry and mouse menu operations by performing elaborate preprocessing.
Not only does it make word searches easier, but it also allows you to read the text from a birds eye view by making use of multi-colored markers.
This is especially effective when reading difficult texts.
Examples are research and development (especially in mathematics and law), schoolwork, and certification exams.
This is because while the same words appear frequently, an understanding of the concepts that combine them is required.
They are easily identified when highlighted.
It is also useful for foreign language learning.
Highlighting unfamiliar words reduces the apparent number of unfamiliar words.
You can also increase the probability of guessing unfamiliar words in association games.

With tap highlighting extensions, this is easily achievable.
No keyboard, mouse, tap menu selection, or flick input required.
No need to select colors. Automatic color toggling (see video).

The reading experience has never been possible before with high-speed, multi-color highlighting.
