Is it possible to organize monitoring of site page changes using the Yahoo pipe?

Question

Yahoo

Is it possible to organize monitoring of site page changes using the Yahoo pipe?
Namely:
1. Store the state of the site's pages (texts and html)
2. Compare the text and html of the previous version of the page with the current version of the page
3. Send by email once a day which pages have changed and how.
Something like paid services sorge.pro and neowatcher.com .
The goal is to organize tracking of changes to the entire site.
