Grok.

Every major AI chatbot can answer questions about last year’s news. Grok’s party trick is answering questions about what happened ten minutes ago. Built by xAI and wired into both the web and the live post stream on X, Grok tells you what is happening right now — then helps you write, code, create images and generate short videos without leaving the conversation.

In this Grok review we cover how it works, its standout features, what the free tier gives you, how the paid plans are priced, and the honest drawbacks — including a watermark rule creators need to know about.

What Is Grok?

Grok is an AI assistant created by xAI. Use it at grok.com, inside X, or through its iOS and Android apps, with conversation history synced across devices when you sign in with your X or email account. It chats in text or voice, searches the web and X in real time, reasons step by step, writes and debugs code, analyses uploaded files, and generates images and video through its Imagine tools.

The personality is part of the pitch. Grok is deliberately more direct than most assistants, and its live connection to X grounds its answers on news and trends in posts appearing as you ask — not a training set that froze months earlier.

Key Features

• Real-time search with citations: Grok searches the web and X live and backs answers with citations from primary sources, so you can check where a claim came from.
• Multi-agent reasoning: on harder questions, multiple agents tackle sub-problems in parallel, each showing its reasoning, and merge into one coherent, cited answer.
• Deep reasoning you can follow: step-by-step thinking is shown, not hidden, making it easier to spot where an answer went wrong.
• Grok Imagine: generate images and video from text prompts or reference photos in the same thread, and edit results with follow-up prompts — images up to 2K, videos up to 15 seconds at 720p.
• Natural voice conversations: talk to Grok with low-latency back-and-forth voice instead of typing.
• File and PDF analysis: upload documents, spreadsheets, code and images — up to around 100 files at once on the web — for summaries, extractions and answers.
• Everyday depth: code generation and debugging, vision understanding for screenshots and photos, a Canvas for long-form writing, custom instructions, memory across chats, shareable conversation links, and more than 30 languages.

How to Use Grok

1. Go to grok.com, or install the Grok app on iOS or Android — trying it is free.
2. Sign in with your X account or email so chats sync across devices.
3. Type or speak your question. For current events, Grok automatically searches the web and X and cites its sources.
4. Switch modes as needed — deeper reasoning for a hard problem, or Imagine to generate an image or short video from a prompt.
5. Upload files with the + button to summarise a document or analyse data, and share any thread via a public link.

Grok Pricing

Grok is free to try on the web and in the apps, with limited chat and agent requests. On grok.com the paid upgrade is branded SuperGrok — higher limits, priority access and multi-agent reasoning — and paid plans draw from one shared weekly usage pool spendable across Chat, Imagine, Voice and other products, with optional Extra Usage Credits (from $5) if you run out. Grok is also bundled with X Premium. The consumer tiers on xAI’s official pricing page are:

Plan	Price	What you get
Free	$0	Grok on web, iOS and Android with limited chat and agent requests — enough to judge the answers before paying
Plus	$8/mo	Shared AI usage pool covering Grok Chat, Voice, Imagine and Build, Grok API access, plus X Premium features such as the checkmark and fewer ads
Premium	$30/mo	Everything in Plus with roughly 4x more usage, Grok Bot, latest Grok models, faster chat, image and video generation, code hosting with AI reviews, cloud agents, ad-free X
Super	$100/mo	Everything in Premium with roughly 15x the usage of Plus and priority model access at peak times

An Enterprise option with custom rate limits, SSO and volume pricing is sold via xAI’s sales team. Prices exclude taxes and can change — plan names have been reshuffled before, so check the pricing page before committing to a year.

Pros and Cons

Pros

• Real-time knowledge of news and trends via live web and X search, with citations to check
• One assistant for chat, reasoning, coding, documents, images, video and voice
• Multi-agent mode shows its working, building trust on complex questions
• Usable free tier on web, iOS and Android; paid plans share one flexible weekly usage pool
• Strong value at the entry paid tier if you also use X, since X features are bundled

Cons

• Free-tier limits are real but not published in detail, so you cannot tell exactly when you will hit the wall
• Generated images and videos carry a Grok watermark that, per xAI’s FAQ, cannot be removed
• Live X data is a strength and a weakness — breaking-news answers can surface rumours alongside facts, so check the citations
• Plans, names and limits change often, making long-term budgeting less predictable than with slower-moving rivals

Who Should Use Grok?

Grok is best for people who live on X and follow fast-moving topics — journalists, traders, social media managers, news junkies — because no rival is as plugged into that stream. It also suits anyone wanting one subscription for chat, research, coding and media generation. If you prefer calmer, more conservative answers, compare alternatives first: our Claude Opus 5.5 review covers Anthropic’s flagship for careful long-form reasoning, while the GPT-6.1 Sol review looks at OpenAI’s latest. Grok’s edge remains freshness — when a story is still unfolding, it is usually the first chatbot to know.

Final Verdict

Grok has grown from a novelty chatbot into a genuinely complete AI assistant. Real-time search is still its clearest advantage, but the reasoning transparency, media generation and file handling now hold up against any rival — and the free tier means you can test it on your real questions before paying. If your world moves fast and lives partly on X, Grok is the assistant built for it.
