OpenAI has confirmed it will retire ChatGPT Atlas, its standalone AI-powered browser, less than a year after its debut, as the company integrates its key browsing and AI agent capabilities into a redesigned ChatGPT desktop app and a new Chrome extension.
Atlas, which launched for macOS in October 2025 as an AI-first browser built around ChatGPT, will officially reach the end of support on August 9, 2026. OpenAI said users will receive transition details through email and in-app notifications ahead of the retirement.
Rather than continuing Atlas as a separate product, OpenAI is bringing its core features into a unified ChatGPT desktop application that combines ChatGPT, Codex and ChatGPT Work on a single platform.
The new desktop app features an integrated browser that can browse websites, compare information from multiple sources, access files stored in Google Workspace and Microsoft 365, and continue long-running AI tasks in the background while users work on other activities.
In addition, OpenAI is rolling out a Chrome extension that places ChatGPT directly in the browser sidebar. The extension enables users to summarize webpages, ask questions about online content and complete AI-assisted tasks without leaving Chrome.
ChatGPT Atlas was introduced as an AI-first browser featuring an Agent mode capable of performing tasks on behalf of users. However, it remained exclusive to macOS, while its advanced automation features were limited to paid ChatGPT subscribers. Early user feedback also indicated that some AI-driven tasks were slower than completing them manually.
By retiring Atlas, OpenAI is shifting its strategy away from developing a standalone browser and instead embedding AI-powered browsing directly into the ChatGPT ecosystem. The move also means the planned Windows version of ChatGPT Atlas will no longer be released.
On the other hand, after just three and a half years since its release in November 2022, ChatGPT is now the fastest app in history to reach 1 billion monthly users.
The market research firm Sensor Tower estimates that no other app has reached the milestone more quickly.
Google Maps, the previous record holder, achieved the same milestone in about five years.
Users are based on who is active on the app each month and exclude those who access ChatGPT via other platforms or the web.
