OpenAI on Tuesday announced ChatGPT Atlas, a new artificial intelligence-powered web browser.
The company said the browser was built around ChatGPT, and users will be able to open the chatbot as a sidebar on any page to help offer summaries, explanations or to carry out tasks within a window.
The launch of ChatGPT Atlas puts OpenAI in direct competition with rivals like Google and Perplexity AI, which are jostling to attract users and win market share with their own browser offerings.
Shares of Alphabet, Google’s parent company, sank about 3% on the announcement.
“We think that AI represents a rare once-a-decade opportunity to rethink what a browser can be about,” OpenAI CEO Sam Altman said during a livestream on Tuesday.
ChatGPT Atlas is available to macOS users worldwide, and OpenAI said experiences for Windows, iOS and Android are coming soon.
