OpenAI needs a web browser if it's going to be truly useful. So Sam Altman will have a big job on his hands to convince people to use his new one.

OpenAI on Tuesday unveiled a free web browser that is designed to work closely with the company’s artificial intelligence technologies, including the chatbot ChatGPT. The new browser, called Atlas, is a direct challenge to tech giants like Google, Apple and Microsoft, whose browsers have long dominated the internet.

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

Shares of Google's parent company took a hit as OpenAI CEO Sam Altman pitched ChatGPT Atlas as the future of web browsing.
