I've been looking for a decent scanning application for OS X so I can digitize, organize and shred all of these boxes of paper. The software that came with my HP all-in-one only creates one page PDFs. Useless. I have to use Automator every time I want to concatenate PDFs.

kip looks promising. Scan multiple pages, tag and search PDFs, very slick UI. I can see the tagging leveraging my sloppy habits. You can't beat the price: currently free. Looks like I have a long weekend ahead of me. Maybe I should pick up a multi-page scanner...
