X is broadening access to its AI-powered chatbot, Grok, enabling users to mention it in replies to ask questions and receive explanations about posts.
The expansion, noted by multiple users, marks a step toward deeper AI integration within the Elon Musk-owned platform.
Previously, Grok was accessible via a sidebar button and a dedicated option next to posts, allowing users to receive AI-generated explanations of text and images—a feature introduced last year.
