OpenAI is quietly working on its AI-powered web browser, internally codenamed “Aura,” signaling a bold step toward challenging traditional browsing experiences with generative AI.
The discovery was first shared by X user Tibor, who uncovered references to “Aura”, “is Aura Sidebar,” and “in Aura” embedded in the ChatGPT web app’s codebase. These terms suggest Aura may operate as both a standalone browser and a browser-integrated assistant or sidebar experience, similar to Microsoft’s Copilot integration in Edge.
According to Reuters, OpenAI’s browser will likely be based on Chromium—the same open-source engine behind Google Chrome, making it cross-platform ready from day one. The browser is expected to fuse generative and agentic AI capabilities, offering users a radically smarter way to search, summarize, and interact with web content.
Interestingly, OpenAI has also shown interest in acquiring Google Chrome itself if the ongoing U.S. antitrust lawsuit against Google ends with forced divestitures. While such a move is speculative, it hints at OpenAI’s ambitions to become a dominant player in web browsing.
Alongside “Aura,” OpenAI is also making progress on multiple fronts:
- GPT-5, its next flagship AI model, is in the works. It’s expected to combine major advancements across all previous models for a significantly improved experience.
- A computer agent is being tested inside ChatGPT’s “chain of thoughts,” though details remain scarce. It could potentially allow ChatGPT to act as a more autonomous task manager across software and devices.
As competition heats up—especially with AI-native browsers like Perplexity and Arc gaining traction—OpenAI’s Aura project could redefine what users expect from everyday browsing. Whether as a sidebar assistant, a full-fledged browser, or both, Aura represents OpenAI’s deeper push into the consumer internet
