How to use Grok: a beginner’s guide

How to start using Grok

Grok is xAI's AI assistant, and the quickest way in is through X (formerly Twitter), where it's built in; it also has its own app and website. Open it, type a question in plain language, and refine from there — it works like any chat assistant. Access and limits depend on your plan, so check the current options. New to what it is? Start with what is Grok.

What Grok is best at

• Real-time questions — trending topics and live discussion on X, where most assistants lag.
• Casual conversation — a looser, more irreverent tone if other assistants feel stiff.
• Quick takes — fast, conversational answers on what's happening now.

For long documents, precise reasoning, or sensitive work, steadier all-rounders like ChatGPT and Claude are often the better call.

How to get better answers from Grok

The same fundamentals that work everywhere work here: give it a role, the context, the task, and the format you want. Lean into its real-time strength by being specific about timeframe and source ("summarize what people on X are saying about X today"). And because any model can be wrong or biased, verify anything that matters. For the full method, see how to write a good prompt.

When to use Grok vs other tools

Reach for Grok when you want a live read on a trending topic or a casual back-and-forth; keep a polished all-rounder as your default for general work. The real skill isn't picking one tool — it's directing whichever you use well. That's AI fluency, and you can build it in about 5 minutes a day. See the wider field in the best AI apps.
