ChatGPT App
The ChatGPT app gives users a familiar place to start sessions and review payment-related state while Aftercard keeps protected values outside model context.
What It Is For
The ChatGPT app is a cross-platform Aftercard client. It can show Aftercard Card state, payment sessions, requests, top-up flows, and approval UI.
MCP Role
The app exposes Aftercard flows over MCP, so ChatGPT can start or continue a session while the backend keeps request handling.
User Control
Payment approvals and protected-data requests still go through Aftercard. Users may choose chat convenience for reusable Memory facts, but raw secrets and card values typed into ChatGPT are model-visible and cannot be retroactively protected by Aftercard.
