OpenAI turns ChatGPT into an app platform with third-party sign-in

OpenAI is expanding ChatGPT into a platform where users can discover, launch, and interact with software directly within the chatbot, the San Francisco-based company announced. At its Dev Day event in late September, OpenAI introduced interactive app interfaces, a "Sign in with ChatGPT" feature for third-party apps, and an enterprise marketplace with partners like Adobe and Salesforce. The company also unveiled agentic "Dots" that can access over 4,000 apps to complete tasks with user approval. OpenAI has not yet announced a billing or revenue-sharing system for the ecosystem, leaving its economic model unresolved. Meta recently launched a similar consumer AI assistant called Muse, which topped Apple's US App Store, while OpenAI cancelled a new AI model release due to security concerns.
