OpenAI is testing an AI-powered browser that uses Chromium as its underlying engine, and it could debut on macOS first.

My sources tell me that OpenAI has already started updating ChatGPT to power the Chrome rival.

OpenAI is building an AI-powered tab selection, a new tab page, and a feature that allows the browser to do the browsing for you. It could be similar to Copilot mode in Edge.

OpenAI already has Agent mode in ChatGPT.

For those unaware, Agent mode in ChatGPT is powered by a Linux terminal and uses the Chromium browser to execute tasks in the cloud, and it handles requests like “create a PowerPoint presentation using my documents and internet sources.”

I’ve been using Agent mode in ChatGPT for a while now. It’s very good and neatly handles most of my tasks.

My sources tell me that OpenAI’s browser is based on a unified agentic system, but I wouldn’t be surprised if it ends up looking like Chrome. I mean, at the end of the day, it’s a browser.

Reuters previously reported that a ChatGPT-based browser will give you more reasons to stay inside the chat interface of the browser than visiting websites.
