ChatGPT-maker OpenAI on Tuesday announced an "Atlas" search browser, leveraging its artificial intelligence prowess in a direct challenge to Google Chrome.
"This is an AI-powered web browser built around ChatGPT," OpenAI chief Sam Altman said in a streamed presentation.
OpenAI has been ramping up its challenge to Google, which has responded by rapidly building more AI capabilities into search and across its platform.
Shares of Alphabet, which owns the Chrome browser, were down 2.6% in afternoon trading, Reuters reported.
The product is the latest entrant in a fast-crowding field of AI browsers that includes Perplexity's Comet and Opera's Neon as companies weave in tools that can summarise pages, fill out forms and draft code to attract users.
Atlas lets users open a ChatGPT sidebar in any window to summarise content, compare products, or analyse data from any site.
In the agent mode in Atlas, ChatGPT interacts with sites for users, who can use it to do tasks from start to finish, like researching and shopping for a trip.
The browser is now available globally on Apple's macOS. It will soon be made available on Windows, iOS and Android.
Reuters had in July reported the AI startup, backed by Microsoft, was close to releasing an AI-powered web browser that will challenge Alphabet's market-dominating Google Chrome.
