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.

OpenAI's new Atlas browser offers powerful new capabilities, though the combination of Web and chatbot data opens up a new world of risks related to privacy and security. Why it matters: People are already sharing some of their most sensitive thoughts and information with ChatGPT.

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.

Over on the site formerly known as Twitter, an ethical hacker who goes by Pliny the Liberator has discovered a concerning vulnerability in Atlas. According to the hacker, the browser is susceptible to a type of attack known as clipboard injection. The hacker also shared a video showing proof of the vulnerability.

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.
