What is Grok and how it can help you be more productive
|AI
Grok is the AI assistant built by xAI, Elon Musk's artificial intelligence company now branded SpaceXAI. Launched in November 2023 as the first chatbot embedded directly inside X, Grok has grown into a full assistant family: the Grok app, real-time answers grounded in the X platform, image and voice features, a coding agent called Grok Build, and the Grok 4.5 and 4.6 models that now rank at the frontier. In this guide, we explain what Grok is, how the Grok 4.x model family works, what real-time X data actually changes, what the plans cost, and how to use Grok well - for research, writing, coding, analysis, and everyday productivity.
