Atlas debuts as Silicon Valley races to use generative AI to reshape how people experience the internet. Google has also announced a plethora of AI features for its popular Chrome browser, including a “sparkle” button that launches its Gemini chatbot. Chrome remains the most used browser worldwide.

ChatGPT Atlas looks and works much like a standard web browser but infuses generative AI capabilities throughout the experience.

With OpenAI’s release of the ChatGPT Atlas web browser, we evaluated its reviews next to Perplexity’s Comet in the battle that’s reshaping how we use the web.

In OpenAI’s new Atlas browser, the Ask ChatGPT sidebar is moderately helpful at best. Sometimes, it’s confusingly wrong.

An ethical hacker demonstrated that ChatGPT Atlas is vulnerable to clipboard injection attacks. Atlas' agent mode might click on a malicious link that hijacks your clipboard without you knowing it, leading you to paste a malicious link in your browser.

Recent versions of Edge already had many of the same features found in competing AI web browsers, such as Perplexity's Comet, OpenAI's ChatGPT Atlas and Google's Gemini in Chrome. This includes having an AI in the corner to chat about the web page you're looking at, analyze content across multiple tabs, or search the web.

OpenAI, Google—and probably others—will engage in a battle that could fundamentally change the way we use the web.
