Paperwork is a free, open-source document management tool available for Linux and Windows. It allows users to import various document types, including PDFs, DOCX, and ODT files, and provides features for tagging, labeling, and searching documents. Users can search by file name or specific text strings and filter results by labels or dates. Installation is straightforward for both Linux and Windows, with specific commands provided for different distributions. Paperwork organizes documents by date and attempts to auto-label them, though users may need to adjust labels manually.
