CartAI

An AI agent that automates completing transactions such as checkouts, subscription sign-ups, invoice payments, and order submissions on any web property. It solves the problem of reliably navigating web surfaces and clearing transactions, handling everything between the click and confirmation. It sells to software developers, engineering teams, and businesses building automated workflows or needing embedded checkout functionality. It is positioned as a specialized primitive focused on transactional reliability, distinct from general browser automation or payment rails alone, delivered via an API, MCP server, or hosted cart component.
