Mod Notebooks is a paper notebook that will sync to the cloud. For $25, Mod will send you a blank, ruled, or dot-gridded notebook in the color of your choice. Once you've filled it up, you drop it in a prepaid envelope and ship it off to Mod, where they will scan and digitize every page as a 600 DPI image you can view on their app or export as a PDF to Evernote, Dropbox or OneNote.
