Introduction
In a strategic move redefining the role of generative AI, OpenAI has officially announced the opening of third-party app submissions for ChatGPT. Starting today, December 18, 2025, developers can submit their tools for review and publication in the new App Directory. This evolution marks the definitive shift from simple "GPTs" (prompt wrappers) to fully integrated software applications, enabled by the new Apps SDK and, crucially for the industry, support for the Model Context Protocol (MCP).
The news, hinted at during DevDay and confirmed by today's announcement, transforms ChatGPT from an advanced chatbot into an AI operating system, allowing for native interactions like ordering products or managing complex workflows without ever leaving the chat interface.
Analysis and Details: The Leap to MCP
The core of this announcement is not just the "storefront" for apps, but the underlying technical infrastructure. According to the released documentation, OpenAI has adopted standards that favor interoperability. The new apps rely on two fundamental pillars:
- Apps SDK (Beta): Allows the creation of native user interfaces (Widgets) within the chat. Unlike text-based plugins, these apps can display charts, maps, or interactive forms directly in the conversation flow.
- Model Context Protocol (MCP): OpenAI now requires "MCP connectivity details" during submission. The adoption of this protocol, initially standardized by Anthropic, is a massive signal of industry consolidation: MCP acts like a "USB-C for AI apps," allowing developers to connect data and tools to LLMs in a standardized way.
The approval process involves a hybrid (automated and manual) review to ensure safety and privacy. Once approved, apps will be rolled out gradually in early 2026 and can be invoked by users via "@" mentions (e.g., @appname), similar to Slack or Discord, or discovered contextually by the AI itself.
Market Impact: The End of "Plugins"?
This move positions OpenAI in direct competition to become the primary interface of the internet. While Google pushes Gemini extensions and Anthropic paved the way with MCP, ChatGPT's massive user base offers developers a unique incentive.
High-profile partners like Apple Music, Salesforce, and Canva are already on board, demonstrating that the ecosystem is ready for the enterprise leap. However, the crucial sticking point remains monetization. Currently, OpenAI allows transactions for physical goods only via external links (websites or native apps). Native digital goods sales are planned, but details will only arrive over the coming year, leaving developers in a "strategic investment" phase waiting for a clear revenue share model.
Conclusion
By opening up to third-party apps and implicitly adopting standards like MCP, OpenAI is attempting to replicate the "App Store" effect of 2008. For developers, this is the starting gun: building today means securing a front-row seat in the directory that could replace the browser for millions of users.

FAQ
How do the new Apps differ from GPTs?
Apps are full software integrations based on the Apps SDK and often the MCP protocol. Unlike GPTs, which are primarily prompt instructions, Apps can feature native graphical interfaces (UI) and handle complex data connections.
Can I monetize my App on ChatGPT?
Currently, you can link the App to your website to sell physical goods. Direct monetization of digital goods within ChatGPT is being explored, with details expected to be released in 2026.
What is the Model Context Protocol (MCP) mentioned?
MCP is an open standard that allows applications to provide data and tools to AI models securely and uniformly. OpenAI uses it to facilitate the connection between ChatGPT and external services.
When will apps submitted today be visible?
Submissions are open immediately (December 2025), but the first batch of approved apps will begin rolling out gradually to users early in the new year.
