Use Case
Stop doing repetitive communication tasks manually. Index Cards lets your AI agent handle them automatically through natural conversation. Send real, physical greeting cards through the mail. Design custom cards with the user, print on premium cardstock, and mail with a first-class stamp. Use when the user wants to send a card, mentions a birthday or occasion, or asks about greeting cards. Requires a free API registration (POST /v1/auth/register returns a Bearer token). Works via API β no browser needed. Homepage https://indexcards.com β privacy policy at https://indexcards.com/privacy.
