Cardnasium

Cardnasium is an online platform that allows users to create personalized physical greeting cards. Users can select from various templates, add custom messages and images, and then have the cards printed and shipped to their desired recipient.

Cardnasium offers customized greeting cards with a selection of templates and personalization options, including adding images. They categorize cards by occasion. However, the core concept of GreetsU is a *free online greeting card maker* that allows *instant sharing via link, email or social channels* and features *live preview with animations*. Cardnasium, on the other hand, is a service where you *purchase* and they *print and ship* the physical card. While it has some matching features like template selection, personalization, and photo upload, it fundamentally differs in its delivery method (physical vs. digital) and business model (paid physical product vs. free digital maker). It lacks the live preview, animations, and direct digital sharing capabilities that are must-have features for GreetsU.
