Avoiding 'Decorating Cards' appears to be your unique selling point, as it is the most prominent headline text on your website and mentioned twice in your text here.

The meaning of this is obvious to you, while being obscure for me. Perhaps have a link within your site to expand on the meaning of 'Decorating Cards'. ( I assume it is prettifying. Perhaps it is initial card creation, or bulk loading. Perhaps it is includes other steps. ) Describe how your software is superior to putting minimal effort into using default anki cards with text and images.

OP is not a native English speaker and thought "decorar", the Brazilian Portuguese verb for memorize (with a "mindless memorization" subtext) translated to "decorate".
