The ChatGPT app has been updated to include a Safari extension that allows users to set ChatGPT as the default search engine on iPhones and iPads. This feature was highlighted by multiple users, who noted the convenience of integrating ChatGPT into their browsing experience. Additionally, there have been discussions regarding ChatGPT's limitations in generating images, specifically a rose, with users reporting that requests for such images were rejected. The app's latest update is expected to enhance user engagement by providing more functionalities directly within the Safari browser.
