        "On October 6, 2025, OpenAI announced apps that could be used inside a ChatGPT conversation and an Apps SDK preview for developers. The release said apps were available that day to logged-in Free, Go, Plus and Pro users outside the European Economic Area, Switzerland and the United Kingdom. It listed Booking.com, Canva, Coursera, Figma, Expedia, Spotify and Zillow as pilot partners, available in English where their services were offered. Those details define a bounded launch rather than a blanket claim that every ChatGPT user could use every third-party service. The page also later noted a November update that made apps available in preview to Business, Enterprise and Edu customers. That later status is not proof of the original October audience. Plan, region, language, partner service area and account state all mattered to the announced surface."

      "heading": "The product joined natural-language requests to in-chat interfaces",
      "paragraphs": [
        "OpenAI described two discovery paths for an app: a person could name an available app in a message, or ChatGPT could suggest one when it appeared relevant. The launch examples paired conversational intent with an interactive map, playlist, presentation or course context. This was a product-interface claim, not an assertion that ChatGPT could independently select a trustworthy provider or finish a consequential task. The dated post said the first use would prompt a person to connect an app so they could understand what data might be shared with its developer. That connection moment is material because it separates a chat mention from a granted external relationship. The announcement did not show a particular user authorization, provider account entitlement, action scope or result. A real workflow still needed to make visible which account was connected, what an app could read or write, and which person remained responsible for reviewing a proposed action."

      "paragraphs": [
        "For developers, the October page said the Apps SDK was available in preview and built on the Model Context Protocol. OpenAI described the SDK as extending MCP so a developer could design both an app's logic and its interface, while connecting directly to an existing backend for customer login or premium features. It said the SDK was open source and intended to let apps run wherever the standard was adopted. The release also directed developers to documentation, examples and Developer Mode for building and testing. These statements establish the announced development model, not a security certification or a production approval for all software made with it. An open protocol basis does not remove the need to authenticate users, scope backend calls, handle errors, protect data or test an interface. The release's own use of the word preview signals an evolving product and developer surface."

      "heading": "Current connection controls keep provider access and approval separate",
      "paragraphs": [
        "OpenAI's current connected-apps help record says an app may search, reference, sync or take supported actions, but each task is limited by the connected account's existing app permissions. It distinguishes app capabilities from workspace settings, role permissions and approval requirements, and says permissions do not grant an app new access. The guide also identifies current choices such as allowing reads or low-risk actions, with sensitive actions potentially requiring approval or being denied. This is current product context, read after the launch. It gives a practical way to assess an in-chat integration, but it cannot establish the exact October 2025 permission menu, partner contract, data flow or availability. The historical event supports the Apps launch and its stated consent prompt; present-day controls support a separate claim that a live integration must still respect the provider's authorization and the workspace's governance."
