From Bare Bones Software:
Yojimbo makes keeping all the small (or even large) bits of information that pour in every day organized and accessible. It's so simple, there is no learning curve. Yojimbo's mechanism for collecting, storing and finding information is so natural and effortless, it will change your life, without changing the way you work. There are as many uses for Yojimbo as there are users of it. It accepts almost anything -- text, bookmarks, PDF files, web archives, serial numbers, passwords, or images -- by dragging, copying, importing or even printing. You can get anything out of Yojimbo you put into it, too, in its original form. There's no lock-in, export any time.
What's new in this version:
Yojimbo 3 includes a number of notable changes; these are just the highlights. There's now a Yojimbo companion app for the iPad, which syncs from Yojimbo on your desktop. If your Mac has a TWAIN compatible scanner connected, you can now directly scan images into Yojimbo.
