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).
Other cool things include the ability to zoom in by mousing over sections of a document in the central pane’s catalogue view.
Currently Kip is a free demo but they’ll be charging for future versions.
