What is Grok?

Grok is the chatbot from xAI, the company founded by Elon Musk, available on grok.com, in its own mobile app and inside X (formerly Twitter). What sets it apart is its data source: it can search live posts on X directly, so it is quick to answer questions like “what are people talking about right now”.

The other thing it is known for is tone. Where ChatGPT and Claude are careful and measured, Grok is more direct and casual, sometimes jokey, and more willing to engage with topics other models sidestep. Fans find that refreshing; others find it lacks composure.

Keep in mind that X itself is full of mixed-quality information, and “real-time” does not mean “accurate”. Grok reacts fast to breaking news, but it can also repeat unverified rumours as fact. It works better as a way to read the mood on social media than as an authoritative source.

Key features

Real-time search: Searches X posts and the web to follow events and conversations as they happen.
Deep search: Runs several rounds of searching on a complex question and compiles a fuller analysis.
Reasoning mode: Lets it think before answering on maths, code and similar problems.
Image generation and understanding: Creates images from text and reads images you upload.
Voice conversation: Talk back and forth by voice in the mobile app.

How to use

Go to grok.com or install the Grok app.
Sign in with an X account, a Google account or email.
Ask directly; for the latest developments, include a timeframe such as “today” or “this week”.
For complex questions, switch on deep search or reasoning mode and expect a longer wait.
Open the posts and links it cites and verify them, especially for breaking news.

Best for

Following hot topics: tech, crypto and international politics — the subjects most discussed on X.
Reading public sentiment: a quick sense of the mainstream views and flashpoints around an event.
Casual conversation: an AI companion that doesn’t talk like a press release.
Heavy X users: call it up while browsing X without switching tools.

Strengths and limitations

Strengths

Direct access to live X content gives it unusually fresh information.
Answers are direct, with less hedging on sensitive topics.
Deeply integrated with X, which is convenient for X subscribers.

Limitations

X content varies wildly in quality, and answers may repeat unverified claims.
Its looser style occasionally produces inappropriate output; review it carefully for formal use.
Not reachable from mainland China, and neither is X, the platform it draws on.
Limited coverage of Chinese-language and China-specific information.
