Scan a document as a PDF file (or upload a pre-existing PDF) to OfficeDrop, and the service will apply OCR (Optical Character Recognition) technology to the file so that you can search within the file. This is useful for people who collect a lot of paper documents--receipts, ticket stubs, and the like--but don't have time to organize them for easy retrieval. OfficeDrop can't replace for folks who must prepare detailed expense reports; but this is one of several features that identifies OfficeDrop as a document-management service in the cloud, as opposed to a simple cloud-storage service like Dropbox or SkyDrive.

Your OfficeDrop account comes with a personal email address that allows you to forward emails from your regular email inbox to your OfficeDrop account. OfficeDrop's OCR technology renders these emails and their attachments searchable, provided the attachments are PDFs. --which can be integrated into OfficeDrop--has similar OCR functionality, but that app isn't trying to be a cloud-storage solution at the same time. As OfficeDrop CEO and co-founder Prasad Thammineni puts it, "Evernote is the sticky notes that you stick on your monitor, while OfficeDrop is the filing cabinet."

OfficeDrop's file-synching capabilities are similar to what you'll get with any number of other services, ranging from Google Drive to SugarSync to Dropbox. What sets it apart from these competitors are its document-management features and this new right-click upload tool. Free accounts support one user, a maximum file size of 1GB, 50 pages of OCR storage per month, and 2GB of cloud storage. Sign up for a free account before the end of June, and OfficeDrop will boost your storage quota to 5GB.
