Grok is xAI's AI chatbot, built into X (Twitter) and available as a standalone app, with real-time access to X posts and a built-in image/video generator called Grok Imagine.
Its distinguishing feature is real-time awareness of what's happening on X (genuinely current information other chatbots can't easily access) plus Grok Imagine's Flux-based image generation and Aurora video engine bundled into the same subscription.
Anyone wanting a chatbot with live social-media context, or access to image/video generation without a separate subscription; image generation specifically now requires a paid tier, unlike some competitors' free tiers.
A free tier exists (roughly 10 prompts per 2 hours) but no longer includes image generation as of April 2026. SuperGrok Lite is $10/month for basic Imagine access, SuperGrok is around $30/month, and SuperGrok Heavy runs about $300/month.
