OpenAI has built a hidden shopping feature inside ChatGPT, with a gated Email offers tab that turns a connected Gmail inbox into a feed of promotions and coupon codes, according to a RuntimeWire investigation based on reverse engineering and testing. RuntimeWire traced the interface, route controls and request handlers in signed Windows package 26.1029.7803.0, downloaded on November 4th. The hidden Email Offers tab in the Windows package adds offer cards with "Not verified - Email source" labels, expiry dates, coupon codes, source email links, retailer links, and a local reference that auto-expires after 30 days or the stated expiry. The report states that the code implements the client feature, but does not establish that the page is enabled for users, that the backend returns offers, or that OpenAI has set a launch date.
