Elon Musk's xAI has launched a standalone iOS app for its Grok AI chatbot in the US, which is currently in beta. The app offers similar features to the one integrated into X, such as providing real-time information and generating images. Initially exclusive to X Premium users, Grok is now free for all. Additionally, xAI is developing a dedicated Grok.com website and has secured significant funding from investors like Nvidia and AMD.
