What is Grok?
Grok is an AI assistant built by xAI, Elon Musk's AI company, and the only mainstream AI with a live, real-time connection to X (formerly Twitter). It can search and read posts from X as they happen — making it uniquely capable for tracking breaking news, public sentiment, and fast-moving conversations that no other AI has access to.
Beyond the X integration, Grok is a capable general-purpose AI assistant: it handles writing, Q&A, analysis, and code. But the live social data is the feature that distinguishes it from every other option.
Plans
| Plan | Price | What you get |
|---|---|---|
| Free (X account) | $0 | Limited Grok messages per day |
| X Premium | $8/month | Higher limits, early features, full Grok in X app |
| X Premium+ | $22/month | Highest limits, full access |
You need an X account to use Grok — there is no standalone signup. If you already have an X account (even the free tier), you can access Grok right now.
The magic moment
Type: "What is everyone on X saying about [today's news event]?"
Grok pulls actual recent posts from X, summarises the different perspectives, and shows you the current pulse of the conversation. No other AI assistant can do this with live social data. For journalists, market analysts, political observers, or anyone who tracks a topic actively, this access to real-time public opinion is genuinely unique.
Step-by-step setup
- You need an X account — sign up free at x.com if you don't have one
- Go to grok.x.ai in your browser, or open the X mobile app
- Sign in with your X account
- Start chatting — Grok is ready immediately, no extra setup
- On the X mobile app, tap the Grok icon in the navigation bar
- Optional: upgrade to X Premium for higher daily message limits
Total time to first message: 2 minutes if you already have an X account.
What Grok is good at
Real-time X analysis: This is Grok's defining capability. Ask it to:
- Summarise what people are saying about a news story right now
- Find the most popular posts about a topic from the last 24 hours
- Compare public sentiment between two competing positions
- Track how a story is evolving over the course of a day
General Q&A: Grok handles everyday questions, factual lookups, and casual conversation reasonably well. It's been trained on the same kind of web data as other major models.
Writing assistance: Drafting emails, posts, and short-form content works fine. Not its strongest use case compared to Claude or ChatGPT, but capable.
Image understanding: Grok can read and describe images — useful for analysing screenshots, charts, or memes shared on X.
What Grok is not as strong at
- Long document analysis (upload a PDF and ask questions)
- Complex, multi-step reasoning tasks
- Coding assistance for large projects
- Long-form writing with nuanced structure
For those tasks, ChatGPT or Claude are meaningfully stronger.
