Kip is designed to let you manage your documents and includes
- Scanning (if you’ve got a Mac OS X ImageCapture compatible scanner, which I don’t. It does let you import images/PDFs)
- .Mac compatibility (hard to know how this works as I don’t have .Mac)
- Tag clouds, which is the first Mac native implementation of them I’ve seen (aside from web browsers, obviously).
- Searching
Other cool things include the ability to zoom in by mousing over sections of a document in the central pane’s catalogue view.
Kip is downloadable from here.
Currently Kip is a free demo but they’ll be charging for future versions.
