I like the idea. Maybe add a very brief explanation about how it learns?

Also please make a tvOS version. It's a perfect fit. :)

Bug report: Copying selected text doesn't work. Mac/Chrome. Via keyboard shortcuts or context menu.

Thanks for the bug report - being added. As for the learning there are a few components at play but ultimately can be thought of as an interest crawler where pages with higher engagement branch deeper into their on page links and similar work from the author/root. As for what your shown, this is based on your interests, the crowds interest, and some other mechanisms in realtime.
