There are a lot of ways to keep track of where you’ve been on the web: browser bookmarks, applications that save selected clippings, shared bookmark services. WebMynd takes a different tack: it saves everything that you see. Built as a Firefox extension plus a backend site, it saves complete versions of every page you browse to, and transmits the text to the backend for indexing.
This gives you several useful capabilities: a visual browser history (somewhat like Apple’s Time Machine) that lets you search back for a page you remember, and an additional set of results when you search Google that shows you pages from your own archive. The service is still in beta and has some rough edges; I got inconsistent results with searching. And you have to watch out for disk usage if you do a lot of browsing. But as a backup for your online activities, it’s hard to beat the convenience.
