Factotum is a "search assistant" for Safari. It opens a small window next to your active Safari window and loads a search page in it. So far, that's nothing you couldn't do by yourself. The unique feature of Factotum is that when you click a link in the little search window, the link opens in your main window--not the search window.
Factotum uses the mobile versions of several popular search and reference sites, because they are designed to fit in small windows. You can choose one of the included sites using the icons at the bottom of Factotum's window.
