WebAssistant updates your cached pages (in the background) so you've always got the latest version to hand. Unlike most offline browsers with this concept, you don't have to specifically tell WebAssistant to capture a website - it remembers everything you see, automatically adding new pages to the cache. The offline browser is a personal proxy server sitting behind your regular browser (Firefox, IE, Safari, Opera - whatever!), silently and speedily handling all the network traffic.
