Overview
UPCgen is a web-based barcode generator designed for e-commerce sellers, warehouses, and publishers. It creates valid UPC, EAN, ISBN, and other barcodes quickly, with options for bulk generation and platform-specific guides. Meridian is an open-source, local-first AI work journal that runs on your device, automatically documenting your workday and drafting status updates for project management tools. While both are productivity tools, they address completely different needs.
