Perhaps read the text? Literally the first paragraph:

> They show students how to use tools known as humanizers and autotypers, which make it easier than ever to cheat.

and later:

> Autotypers slowly drip words and sentences into documents, making it appear as if papers were typed at a human pace when in fact, they were produced by A.I. They even fabricate typos, deletions and revisions.

This only catches the most naive cheaters.
