Grok is xAI's assistant, built by Elon Musk's AI lab and wired directly into X, which gives it something no rival has: a native, real-time view of what the world is saying right now.

Grok pairs xAI's frontier models with live retrieval from X and the web, making it exceptionally current for news, markets, sports, and social sentiment. Its personality is deliberately looser than competitors, willing to joke and engage where others hedge. Grok handles the modern assistant suite: deep reasoning modes, image understanding and generation, voice conversations, document analysis, and a DeepSearch mode that runs multi-step research with citations.

It is available inside X, on grok.com, and through standalone mobile apps, with the heaviest capabilities reserved for paid tiers. For developers, the xAI API exposes the same models.

Who is it for?

People who live on X, traders and news-watchers who need right-now information, and users who prefer an assistant with fewer refusals and more personality. Developers get the API; enterprises, xAI's business offerings.

How much does Grok cost?

Basic access is free with limits. X Premium+ includes expanded Grok access, and SuperGrok at around $30 per month unlocks the highest usage, best models, and earliest features, with a heavier tier above it for power users.

Our verdict

Grok's real-time grounding is genuinely unmatched for current events, and its models are firmly frontier-class. Verify claims as with any assistant, and expect the personality; for live-world questions, it is often the first stop.
