Now you should have a folder of scanned documents, backed up securely. It's time to meet my new best friend - Evernote.
Evernote is a cloud-based platform for note taking and archiving. Each note can contain attachments, be assigned to a notebook, and be tagged with multiple tags. It can then be searched for and retrieved.
Evernote has excellent support for PDF and image attachments, and has a built-in OCR engine for image attachments.
