OpenAI Is Building One App to Rule Them All: ChatGPT, Browser, and Codex Combined

What happened

OpenAI is combining three of its separate products into one desktop application: the ChatGPT app, the Atlas web browser it launched last October, and the Codex coding tool. The Wall Street Journal broke the story on Thursday, with CNBC confirming the details.

The move is being led by Fidji Simo, the former Instacart CEO who joined OpenAI as CEO of Applications last May. In a post on X, Simo said the company is "seizing the moment" as Codex gains traction, and that now is the time to "double down" rather than spread attention across separate products. OpenAI President Greg Brockman is also involved in the consolidation.

The announcement comes days after Simo told staff at an all-hands meeting that ChatGPT must become a "productivity tool" and that OpenAI is "orienting aggressively" toward high-productivity use cases. The company is reportedly targeting an IPO as early as the fourth quarter of this year. It now has 900 million weekly active users and 9 million business users.

The superapp vision is straightforward: one place to chat, browse, write code, and automate tasks, instead of three separate apps that overlap in awkward ways. Think of it like Microsoft Office becoming Microsoft 365 but for AI.

What this means for your business

For most UK business owners, the immediate impact is practical: if you are already using ChatGPT, you may soon find browsing and workflow automation built directly into the same interface. OpenAI is clearly positioning this as a workplace tool rather than a novelty chatbot.

The bigger signal here is where OpenAI thinks the money is. The IPO push and the pivot toward productivity mean the company is betting on business users, not consumers. Expect more enterprise features, better integrations with tools like Microsoft 365 (already announced this week), and pricing that reflects serious workplace use rather than casual subscriptions.

If your team is not yet using AI as a core part of how work gets done, the gap between you and businesses that are is about to get wider. The tools are consolidating and maturing fast.
