OpenAI’s new Chat feature makes ChatGPT more than a chatbot—it’s now a mini OS. Soon, with an AI device launch, users may rely on it instead of apps.

Developers can build mini apps inside ChatGPT, from designing posters to shopping with Instant Checkout—turning it into a full ecosystem like iOS.
This move sets OpenAI apart from Google and Microsoft. But privacy, security, and lock-in risks loom as rivals race to own the AI interface layer.
