xAI's chat assistant, integrated with the X social platform.
Grok is a conversational AI assistant from xAI. It answers questions, drafts text, explains concepts and can search for recent posts and web content, which makes it especially connected to real-time discussion on X. Image understanding and generation are offered in some versions, and availability depends on the app and plan. Grok may appeal to people who spend time on X and want quick answers about ongoing conversations. Its answers on fast-moving or contested topics should be checked against primary sources, because real-time content can be incomplete or misleading. Feature access, usage limits and the free tier change, so check the current terms before relying on a specific capability.
Limited free access; fuller access comes with paid plans. Check the pricing page for current prices.
