If you own a Mac, you can plunge even further into the digital abyss: ScanSnap syncs with DEVONthink, perhaps the most successful artificial intelligence software for home users. DEVONthink, by itself, can open, organize, assess, and store any document that passes through the scanner. Just create and name a database — Coffee, for example — and the program will take any scanned document, read it, and file it in a fully searchable form. You can find all the lattes you ever bought at Starbucks and arrange them by size or the date you bought them. It’s actually a little freaky.
