From MM3Tools Muenzenberger GbR:
MM3 WebAssistant is a personal proxy server sitting behind your regular browser, silently and speedily handling all the network traffic. 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. WebAssistant updates your cached pages (in the background) so you've always got the latest version to hand. There's no difference between surfing the web and surfing your archive; you can even use your bookmarks or search your pages offline when you don't have a network connection.
Work offline (train, plane, beach - wherever you like) without worrying that you have the info you need. Reduces the pressure of knowing what to save, and the necessity for repeating browsing sessions looking for something that was missed.
Incorporate the web into presentations or talks where you don't have internet access. You can sure you'll always have the page you need with MM3-WebAssistant. Mobile users have the flexibility of accessing information from the web without having to worry about expensive access points. Shun overpriced wifi access ports - or at least only pay for what you really need.
