Grok: xAI's AI Assistant, Explained + How to Use It in Singapore

Grok is the AI assistant built by xAI, Elon Musk's artificial intelligence company. It is best known for two things: real-time access to X (Twitter) data, so it can tell you what people are actually posting right now, and a more direct, less filtered tone than most assistants. In 2026 Grok runs on the Grok 4 family of models, with Grok 4.5 rolling out from July 2026, and it includes Grok Imagine for image generation, DeepSearch for research and a Big Brain mode for harder reasoning tasks.

ChatGPT, Claude and Gemini are trained on the open web but do not see live social chatter unless you enable browsing. Grok's edge is that it reads X natively: you can ask what Singaporeans are saying about a topic today and get a genuinely current answer, with posts cited. That makes it useful for market sensing, PR monitoring and content that needs today's context. The trade-off is that its features lean heavily on the X ecosystem, so if you never touch X, much of the magic is wasted.

You do not need to install anything. Three ways in:

• Web: go to grok.com and log in with your X account, or create one.
• Apps: Grok is available on iOS and Android, including a standalone Grok app.
• Inside X: the Grok tab at x.com/i/grok works directly in your feed.

The free tier is enough to try all of this. Image and video generation has required a paid plan since March 2026, but text chat, DeepSearch and X analysis work free within limits.

As of mid-2026, the free tier gives roughly 10 text prompts every 2 hours on Grok 4 Mini, with no image generation. Paid tiers, in US dollars: SuperGrok Lite at US$10 a month, SuperGrok at US$30 a month (about S$40 at typical exchange rates, billed regionally), X Premium+ at US$40 a month if you want X perks bundled, SuperGrok Plus at US$100 a month, and SuperGrok Heavy at US$300 a month for the top reasoning tier. SuperGrok unlocks the newest models, DeepSearch, Big Brain mode and Grok Imagine.

For most people in Singapore the decision is simple: stay free while you explore, then SuperGrok at around S$40 if real-time X intelligence saves you time every week. xAI sets prices in USD and adjusts them locally, so check grok.com for the exact figure before subscribing. Students on a budget can cover a lot of research with the free tier plus X's own trending page.

Real-time X analysis is the standout feature. Four copy-paste prompts to start:

Summarize what Singaporeans are saying about [topic, e.g. COE prices or the latest MRT disruption] on X today. Group the main sentiment, note any recurring complaints, and link the most-shared posts.

Draft a LinkedIn post about [industry news] with real-time context. Use the current conversations on X for a hook, keep it under 150 words, and end with one question for engagement.

Find the top 5 concerns small business owners in Singapore are posting about this week. Summarize each in one line and suggest how a business could respond helpfully.

What is trending on X in Singapore right now? Pick the 3 most relevant topics for a [food/tech/finance] content account and suggest one post idea for each.

For content creators, Grok Imagine can generate social images from a text prompt, and DeepSearch writes short research briefs with sources, handy before a meeting or a pitch. Use it for the first draft, then add your own judgement before publishing anything.

Grok conversations can be used to improve xAI's models, and connecting your X account gives Grok access to your posting history for context. Keep it PDPA-safe: do not paste NRIC numbers, addresses, salaries or customer data into Grok, or into any AI chat for that matter. Treat everything you type as visible to a company, and you can delete conversations in settings if you want a cleaner slate.

If Grok is not for you, the usual alternatives work well in Singapore: ChatGPT, Claude and Gemini, each with free tiers and local pricing. To get better results from any of them, start with our guide to writing AI prompts, and browse the full list in the tools directory.
