The following was crafted by Google's AI and mistakenly refers to the target as Chrome, when, in fact, the browser used by Atlas IS Chrome. It is targeting the Google search engine. It blatantly works by remembering everything you have asked of it (something I suspect all AIs are doing unless you explicitly forbid it - in some cases by using Incognito Mode). This can drive you crazy when it answers a question in the context of a previous unrelated question - as it builds its dossier on you.

OpenAI has released its own web browser called ChatGPT Atlas, featuring a deeply integrated AI assistant. The browser, which is built on Chromium, is designed to challenge Google Chrome and other browsers by reimagining the web browsing experience around AI.
Key features of ChatGPT Atlas

Integrated ChatGPT: Instead of a traditional address bar, users interact with the web through a chat interface. A sidebar also allows for quick summaries or analysis of the current webpage.

AI Agent Mode: A more advanced "Agent Mode" can automate complex, multi-step tasks such as booking appointments, comparing products, or ordering groceries. This experimental feature is currently exclusive to paying Plus and Pro subscribers.

Browser Memory: With user permission, Atlas can remember browsing context and past conversations to provide more relevant suggestions. Privacy controls allow users to manage or clear this memory.

Cross-platform expansion: The browser was first released on macOS in October 2025, with plans to release versions for Windows, iOS, and Android soon.
Impact and reception

Competition with Google: The launch pits OpenAI directly against Google's Chrome, the market leader for decades. Google's stock fell 3% following the announcement.
Data and privacy concerns: Because Atlas provides OpenAI with deep insight into user browsing habits, it raises significant privacy questions. OpenAI has implemented controls like "logged-out mode" to give users more control over their data.

A new AI paradigm: Sam Altman, OpenAI's CEO, framed the launch as an opportunity to rethink the browser for the AI era, shifting internet access toward a chat-centric experience.

Facing market competition: While Atlas is not the first AI-first browser—Perplexity released its Comet browser earlier in 2025—it is the most high-profile entry. Other companies, including Google and Microsoft, are also integrating more AI features into their own browsers.
