What Is Grok? Using the AI Assistant in Your Browser

What is Grok, in short?

Grok is an AI assistant that you use by typing into a chat box. The product's own page describes it as an assistant built by SpaceXSI, made to chat, create images, write code and give real-time answers drawn from the web and from X. There is no separate program you must set up first: it runs as a website that you open in an ordinary browser tab.

Technically, Grok is a genuine progressive web app: the site ships a standalone manifest with a full icon set, the file that lets a browser treat a website like an installed app. It is free to start, installable, and not built for offline use, so every conversation needs a working internet connection. Installing it changes the window, not the way it works.

When the page loads, it greets you with a prompt that asks what you should explore, shows a mode label reading Fast, and notes that you can type a slash to reach slash commands. A line under the box says that by messaging Grok you agree to its Terms and Privacy Policy, with a link to your privacy choices. Read those before you paste anything sensitive.

How do you open Grok and install it as an app?

Open the Grok site in a recent version of Chrome or Edge and you can start typing straight away. Because the site ships its own manifest, both browsers offer a one-click install into a native-feeling window. Look for the install icon at the right end of the address bar, or for the install entry in the browser menu, and confirm the prompt that appears.

After installing, Grok opens in its own window without tabs or an address bar, and it can be pinned to a taskbar or dock like any other app. Nothing about the assistant changes: it is the same website, with the same features and the same limits. If you work on an iPhone, Safari handles installation differently, and the guide on how to install a PWA on iPhone walks through those steps.

You do not have to install it. If you only use Grok now and then, a bookmarked tab does the same job, and nothing is lost by skipping the install step. The benefit of the app window is focus: it separates the assistant from your other tabs, which helps when you keep a long conversation open while you work in a document or an editor next to it.

What can you ask Grok?

The product page names four jobs: chatting, creating images, writing code, and giving real-time answers from the web and X. Ordinary questions, drafting help and explanations fall under chat. Code requests cover writing snippets and talking through a bug. Image requests let you describe a picture and get one back, which is useful for quick mock-ups or illustrations.

A feature worth knowing about is the link to X. The real-time integration is built to answer questions about events from the last hour, which suits breaking news, a trending topic or a live discussion. The free tier also includes image generation and reasoning models, though it is rate-limited, so heavy use will eventually hit a ceiling that the site itself decides.

Typing a slash in the message box opens slash commands, a shortcut feature the page mentions alongside an AI agent label. The selector currently shows Fast. A good habit is to begin with a short, specific request, read the answer, then refine it in follow-up messages, and to check anything important against a primary source before you rely on it.

What does Grok not do, and where does it stop?

Grok does not work offline. The site is not marked for offline use, so installing it gives you a window, not a local copy of the assistant, and a dropped connection ends the conversation. Anyone who needs an assistant on a plane or in a dead zone should plan around that, for example by drafting prompts beforehand and sending them once back online.

The free tier is rate-limited, and the site decides how much you get, so plan for the possibility that a long session pauses. Real-time answers also depend on what is being posted on X and the web at that moment, which means a fast-moving story can be reported incompletely or wrongly. A confident tone is not proof, so confirm anything that matters before acting on it.

Privacy is the other limit worth a minute. The page says that by messaging Grok you agree to its Terms and Privacy Policy and points to a section for your privacy choices, so your prompts are covered by rules you should read first. Keep passwords, client data and personal documents out of the chat unless the policy and your own obligations allow it.

Is Grok free, and where do you read current terms?

As of November 2026, Grok is free to start with: it offers a rate-limited free tier that includes image generation and reasoning models. Exact limits and any paid plans are set by the site and can change, so check the account screens inside Grok before you decide. The Terms and Privacy Policy linked under the message box are where current conditions are published.

If Grok is not the right fit, two other listed apps cover different needs. Claude installs the same way and is aimed at long-form writing, coding help and document analysis, with a free tier and Artifacts that render generated code and documents in a side panel. OpenRouter is a unified interface for many models, whose homepage promises no subscriptions, and it needs a connection because it caches nothing for offline use.

To see Grok next to other assistants, open the Grok listing, which shows its category, install status and a link to the live site, or browse the wider Productivity category. For another browser-based assistant and how its free access works, the write-up on Google AI Studio and whether it is free is a useful companion.
