A new prototype Internet Explorer add-on from Microsoft Research called “Diff-IE” help you:
- Highlights the changes to a page since the last time you visited it
- Allows 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 web pages you visit.
This simple but ingenious plugin caches multiple copies of websites you open (by default, last five visits) and on subsequent visits compares the contents and highlights any changed text elements. Optionally, you can also enable to save an image-cache of each visit which you can later view or compare side-by-side.
In a test conducted with 30 users over a month, the researchers’ found their tool had a positive effect on revisitation patterns and perception of web content. They also noted “some participants reported the highlighting had become an indispensable part of their browsing”.
