Funnily enough, I use a commercial app with the same name (Paperless) that does exactly that. It scans the documents, applies OCR and saves the pdfs in a folder that, in my case, is automatically synced with dropbox and backed up to a local NAS.<p>It doesn&#x27;t have search functionality (well, it does, but it&#x27;s basically useless) but allows to set categories and tags, which is more than enough for me.<p>There&#x27;s an added issue with this kind of solutions, in most cases you still need to keep the original. Having them scanned is great for record keeping and for communicating with you own accountant, but if there is a problem (tax audit, proving ownership, etc, etc) you&#x27;ll have to produce the paper original.
