Claude, ChatGPT, and Cursor can list the books on your account, add a photo, and hand you a checkout link. Sign-in is the same email code. The payment still happens in your browser.
Books, pages, images, and orders that already belong to the signed-in account.
Upload a photo and wait for the coloring page. The free generation quota still applies.
Invite family onto a book, or publish it when the pages are ready.
The agent can prepare a checkout link. It cannot charge a card.
The same sign-up as the coloring-book app. An agent does not get its own login.
Claude, ChatGPT, and Cursor all take one URL. They run the sign-in from there.
You get the email code, then a consent screen that names what the app can read and change. Revoke it later from your account.
