NeatReceipts for Mac scans, saves, and uses optical character recognition (OCR) to save receipt data into a catalogue. It will automatically identify key terms like total, tip, and tax lines and categorize receipts appropriately. A custom-made coverflow view for browsing stored receipts is also available.
For the technically interested, the product is a Cocoa application that uses CoreData for its database and PDFKit for receipt image storage. The company is working on business card support for integration with Address Book, and version 2 will hopefully/probably integrate with Quicken, though no promises.
The company plans to release the product at the end of March. The full version which includes the receipt scanner will ring in at $180, but a software-only version compatible with any image-capture compatible scanner will go for $80. Users of the Windows product can get the Mac version at no additional charge.
