X's Grok AI assistant is now a standalone app

Grok, the AI assistant that's for some reason baked into X, is now available as a standalone app. Like the version that exists as a tab on the social media platform, the Grok app can be used to generate images, summarize text and answer questions, with a conversational tone xAI, the AI assistant's creator, calls "humorous and engaging." The app was first tested with a limited set of users in December 2024, right around the same time X debuted a free tier of Grok that's available to anyone. Prior to that, you needed to pay at least 8 a month for X Premium to have the privilege of using the AI. The limitations of that free access -- 10 requests every two hours, three image analysis request per day -- may also apply to the Grok app.
