Atlas.com AI Browser: OpenAI's ChatGPT Web Experience

Atlas.com AI is a new Chromium-based AI browser built by OpenAI, aiming to change how people use the web. It's often called ChatGPT Atlas or the new OpenAI browser. Nubia Magazine spent time reviewing it in 2026, testing its features and comparing notes with other independent reviews. Atlas launched on October 21, 2025, for macOS. By early to mid-2026, a Windows beta was available, with iOS and Android versions coming soon. The browser uses the Chromium engine, like Chrome and Edge. It integrates ChatGPT directly into its core, acting as a full web browser with an AI sidebar. This sidebar can answer questions about content, summarize pages, or complete tasks. Atlas is free to download and install. However, its advanced AI features are linked to your ChatGPT plan, meaning free users get basic browser functions, while paid plans unlock more AI capabilities. This new browser could change how you interact with the internet.
