Does this work with content that is loaded dynamically with JS? I've used http://www.changedetection.com/ in the past, but it only scrapes the HTML.
I found the 'crawl' settings a little confusing, as the first item is about loading additional URLs (which is what I thought I wanted, as JS is often loaded from separate URLs rather that being embedded in the HTML), but then there's a later option about a full browser. I chose this latter option, and left the other one unchecked. I hope that's correct.
