About Diff-IE

Diff-IE is a prototype Internet Explorer Add-on that:

  • Highlights the changes to a webpage since the last time you visited it.
  • Enables you to view—and compare—previously cached versions of a page.

When changes are made obvious, especially the subtle and unexpected ones, you get a whole lot more out of the webpages you visit.
