Chrome: By default, Chrome records everywhere you go in its history, but not much detail. All Seeing Eye is an extension that also records all the text within the sites you visit, and grabs screenshots so you can easily find pages you've been to in the past.
All Seeing Eye saves every page you visit and all the text on the page is indexed. When you go to Chrome's History page you can search for pieces of text or search for things visually. If you're the type who digs through your history to find stuff a lot, All Seeing Eye makes that process a lot more useful.
