OpenAI has officially entered the web-browsing market with ChatGPT Atlas, a new browser built on Chromium: the same open-source base that powers Google Chrome. At first glance, Atlas looks and feels almost identical to Chrome or Safari. The key difference is its built-in ChatGPT assistant, which allows users to interact with web pages directly. For example, you can ask ChatGPT to summarize a site, book tickets, or perform online actions automatically, all from within the browser interface.
While this innovation promises faster and more efficient browsing, privacy experts are increasingly worried about how much personal data the browser collects and retains.
How ChatGPT Atlas Uses “Memories”
Atlas introduces a feature called “memories”, which allows the system to remember users’ activity and preferences over time. This builds on ChatGPT’s existing memory function, which stores details about users’ interests, writing styles, and previous interactions to personalize future responses.
In Atlas, these memories could include which websites you visit, what products you search for, or what tasks you complete online. This helps the browser predict what you might need next, such as recalling the airline you often book with or your preferred online stores. OpenAI claims that this data collection aims to enhance user experience, not exploit it.
However, this personalization comes with serious privacy implications. Once stored, these memories can gradually form a comprehensive digital profile of an individual’s habits, preferences, and online behavior.
OpenAI’s Stance on Early Privacy Concerns
OpenAI has stated that Atlas will not retain critical information such as government-issued IDs, banking credentials, medical or financial records, or any activity related to adult content. Users can also manage their data manually: deleting, archiving, or disabling memories entirely, and can browse in incognito mode to prevent the saving of activity.
Despite these safeguards, recent findings suggest that some sensitive data may still slip through. According to The Washington Post, an investigation by a technologist at the Electronic Frontier Foundation (EFF) revealed that Atlas had unintentionally stored private information, including references to sexual and reproductive health services and even a doctor’s real name. These findings raise questions about the reliability of OpenAI’s data filters and whether user privacy is being adequately protected.
Broader Implications for AI Browsers
OpenAI is not alone in this race. Other companies, including Perplexity with its upcoming browser Comet, have also faced criticism for extensive data collection practices. Perplexity’s CEO openly admitted that collecting browser-level data helps the company understand user behavior beyond the AI app itself, particularly for tailoring ads and content.
The rise of AI-integrated browsers marks a turning point in internet use, combining automation and personalization at an unprecedented scale. However, cybersecurity experts warn that AI agents operating within browsers hold immense control — they can take actions, make purchases, and interact with websites autonomously. This power introduces substantial risks if systems malfunction, are exploited, or process data inaccurately.
What Users Can Do
For those concerned about privacy, experts recommend taking proactive steps:
• Opt out of the memory feature or regularly delete saved data.
• Use incognito mode for sensitive browsing.
• Review data-sharing and model-training permissions before enabling them.
AI browsers like ChatGPT Atlas may redefine digital interaction, but they also test the boundaries of data ethics and security. As this technology evolves, maintaining user trust will depend on transparency, accountability, and strict privacy protection.
