Elon Musk's AI company, xAI, has unveiled the "Skills" feature for its AI assistant, Grok, across web, iOS, and Android platforms. This new capability allows Grok to retain persistent memory across conversations, transforming it from a simple Q&A chatbot into a programmable automated workspace. With the "Skills" feature, users can teach Grok specific tasks once, enabling it to remember personal preferences, formatting rules, and workflow steps in future interactions. This advancement eliminates the need for users to repeatedly input initial prompts or settings, streamlining the user experience.
