Comparing AI Features in ChatGPT Atlas and Microsoft Edge

Browsers are evolving from merely displaying web pages to becoming AI-powered tools. Notable examples include ChatGPT Atlas and Microsoft Edge. This article provides a step-by-step comparison of the two browsers.

ChatGPT Atlas, developed by OpenAI, integrates ChatGPT directly into its browser interface. It features a persistent ChatGPT sidebar for inquiries, page summaries, text rewriting, and product comparisons. Users can control browser memories and data usage to limit saved information.

Microsoft Edge, a cross-platform browser based on Chromium, incorporates AI features under the Copilot brand. It offers on-page assistance, content summarization, cross-tab reasoning, and Copilot Actions. The browser supports extensions, enterprise controls, and integration with Windows and Microsoft 365.

OpenAI announced ChatGPT Atlas in October 2025, initially releasing it for macOS with plans for other platforms. Microsoft Edge, first launched in 2015, was rebuilt on Chromium and re-released in January 2020. Recent AI features and Copilot Mode were introduced between 2024 and 2025.

ChatGPT Atlas focuses on an AI-first experience with features like page summarization, Agent Mode, and browser memory controls. Microsoft Edge combines standard browser features with an AI layer called Copilot, emphasizing enterprise controls and integration with Microsoft services.

In conclusion, both products illustrate the trend of browsers becoming AI platforms. ChatGPT Atlas is suited for users seeking an AI-native experience, while Microsoft Edge is ideal for those wanting a stable browser with added AI and enterprise readiness.
