You can use Grok inside X and through its own app and website. ## Grok's standout features - **Real-time information** — it can pull in current posts and web results, so it's oriented toward what's happening now. - **Personality** — a more conversational, less buttoned-up tone than most assistants. - **X integration** — it lives where a lot of real-time discussion already happens. ## What is Grok good at? Grok is handy for **keeping up with current conversations** — trending topics, breaking discussion, and what people are saying on X right now. Its casual tone appeals to people who find other assistants stiff. For careful, high-stakes work — long documents, precise reasoning, sensitive tasks — the mainstream assistants like [ChatGPT](/learn-chatgpt) and [Claude](/learn-claude) are often steadier choices.
