I am not sure it *works*. I just tried it on the BILD homepage (a German tabloid with a lot of images instead of text), and it was pretty bad at navigating it. It needed a lot of hints to find a particular article, selected multiple times the wrong article, and in the beginning even, it didn't realize the webpage was in German.

It works well on pages that use a lot of text though, and especially on pages like hacker news. I wonder if this will open up a new stream of work for devs: "Make our web-page AI friendly".
