Grok

Grok is the AI assistant from xAI. You can use it at grok.com, in mobile apps and inside X, where it can draw on live posts as well as the wider web. Beyond chat it offers image and video creation through Imagine, voice conversations and agent features, with a free tier and a long ladder of paid plans.

What Grok is best at

• Live information from X and the web: useful for what people are discussing right now.
• Quick, conversational answers: general questions, writing help and brainstorming.
• Creative media: image and video creation through Imagine on paid plans.
• Heavier reasoning and agents: higher tiers add the newest models and multi-agent modes.
• Coding help: Grok Build, a coding agent that xAI opened to all plans in August 2026.

Plans and pricing

Paid consumer plans share one weekly usage pool across chat, Imagine, voice and build features, so heavy use of one feature leaves less for the others. Prices are approximate because they come from several independent trackers, and they differ by region and billing route. Confirm everything on xAI’s official pages.

Best for

• People who want an assistant with live access to X and web conversations.
• X users who want Grok bundled with a subscription they already pay for.
• Creators who want image and video generation alongside chat.

Less suited to

• Anyone who needs clear, fixed usage limits, because the free limits are unpublished and paid limits are pooled.
• Questions where social media chatter is not a reliable source, since live posts can be wrong or one-sided.
• Organisations that need to be sure about data handling and compliance, who should check the business terms first.

How to get started

1. Try the free tier at grok.com or in the X app to see whether the style suits you.
2. Check which model the free tier includes before you decide you need an upgrade.
3. If you already pay for X Premium, check how much Grok it includes before buying SuperGrok.
4. Upgrade only after you hit the free limits, and watch the shared weekly usage pool.
5. Review privacy and data settings before sharing sensitive information.

Prompt ideas to copy

Search X and the web for what people are saying about [topic] today. Summarise the main viewpoints and tell me which claims look unverified.

Explain [topic] in simple terms, then give me three questions to test whether I have understood it.

Draft three versions of a short post announcing [news]: one friendly, one formal and one light-hearted. Keep each under 280 characters.

Review this plan and argue against it. List the strongest objections and what evidence would settle each one.

Limitations and things to watch

• Answers drawn from live posts can be inaccurate, so check them against reliable sources.
• The plan ladder is long and changes often, and prices differ by region and billing route.
• Free limits are unpublished and may shrink or grow without notice.
• Check how your conversations and posts are used before sharing private information.
