SmileOnMyMac today released a public beta of Browseback, a Web history visualization and search tool. Browseback stores a PDF of every Web page visited and makes the pages accessible through an interface that allows the user to browse thumbnails of the pages. This visual Web history can also be searched by content, making it possible to retrieve visited Web pages with a few keywords. Browseback 1.0 requires Mac OS X 10.4 or later and will be released in December for US$29.95. The beta version is available for download now.
