We can only speculate but I notice Grammarly has a feature for plagiarism detection[0].

How do they know what text is on 16B web pages? Presumably they have a web crawler of some sort.

Can confirm. Caught one of their bots on my site and called them out about it on Twitter.
They did not respond.

The page linked doesn't contain the text.
On a desktop browser, click the "Plagiarism detected" benefit under one of the plans - the text will show up as a tool tip.
That alone doesn't indicate they collected the 16 billion documents themselves, of course.
