How to Use X AI: A Step-by-Step Guide

You can start a Grok conversation on the web or in an app, then choose whether to ask a question, explore current information, or work with a file. Grok is xAI’s conversational assistant, with access through Grok web and app, Grok on X, and the xAI API for developers. A prompt is the instruction and context you give an AI assistant to guide its response.

Users can choose the route that suits their task, then refine a response with a follow-up prompt. You can use a chat for a quick explanation or a longer exchange, and bring in information from files or searches when useful. Your account and the route you choose affect which features are available.

Key Takeaways

• Start a chat on the web or in an official app.
• Use Grok on X when public posts add useful context.
• Try search, file analysis, coding help, or media tools.
• Check plan usage before relying on a feature repeatedly.
• Give Grok a clear task and relevant context.

A clear goal and a little context are the best starting point for a useful first exchange.

How to Use X AI: Get Started

You can get Grok on the web or in its iOS and Android apps, then sign in with either an X or email account. The Grok AI website is grok.com, and the official mobile apps are available for iOS and Android. You can begin a chat after signing in with either account type.

A chat is a good place to test a low-stakes question before relying on Grok for important work.

To use Grok AI, open the website or app and start a chat. The Grok X AI app is one way to reach the standalone assistant, while Grok.com AI offers the same web starting point. To get started, follow these steps:

Get Grok AI at grok.com or in an official app

1. Open grok.com or the official Grok app for your device.
2. Sign in with an X account or an email account.
3. Start a chat from the chat interface.
4. Enter a question or instruction as your first prompt.

That is how to get Grok AI for a personal chat. You do not need an X account if you choose email sign-in. The website and app let you start with a direct request, then add context in a follow-up when the first answer needs more detail.

How to use Grok AI after signing in

After signing in, choose a task that fits the conversation: ask for an explanation, request a summary, or give Grok an instruction. A focused first prompt makes the response easier to judge. You can ask a follow-up if you need a different level of detail or another format.

Grok is available to users who are at least 13 or the minimum age required in their country, whichever is higher. If you are 13 through 17, get a parent or legal guardian’s permission before using Grok, and that guardian must agree to the Terms of Service.

How to Use Grok on X, the Web, Apps, and API

Choose Grok on X when a question depends on current public posts, and choose the xAI API when you are connecting a model to your own software. The right route depends on whether you want a direct chat or developer access. The xAI API is an integration for building a product or workflow, not a consumer chat.

The first four routes let you use Grok directly. Grok on X can bring current public posts into context, which helps when you want to understand a live discussion. For example, ask it to summarize the main points in public posts about a developing topic.

API access serves a different purpose: an application can send requests to a model through an xAI integration. The setup requires an xAI account and an API key. A developer can use that access to connect model responses to a product or workflow instead of opening a consumer chat.

Treat an API key like a credential for an application, not as text to paste into a public conversation.

What Can Grok Do With Web Search, Files, and Media?

A single Grok account can support research, document analysis, coding help, image and video creation, and voice conversations. The main features give you several ways to work with text, files, and media from a chat. Web and X search can add current context to a response.

Search the web and X for current context

Ask Grok to search the web or X when a question needs current information. Search on X can bring public posts into the conversation, which is useful for following a discussion as it develops. For a first try, ask: “Summarize the current discussion on X about electric vehicle charging in three points.”

Tell Grok what kind of information matters, such as key arguments or recent changes. A summary of public posts can help you get oriented, while the original posts provide the details behind that summary. The same chat can combine a search request with a follow-up question.

Analyze documents and work through code

You can upload a PDF or another file and ask Grok to pull out key points, explain a passage, or compare sections. Name the part you care about if the document is long. For example: “Summarize the report’s recommendations in five bullets, using plain language.”

Grok can also write and explain code. If a program returns an error, paste the relevant code and message, then ask what caused the problem. A useful first request is: “Explain this bug in plain English and suggest one fix.” This gives you a readable explanation and a specific next step.

Create images and videos or use voice

Grok Imagine supports text-to-image and text-to-video creation, and you can revise an output with follow-up prompts. Video generation can run up to 15 seconds at 720p. Imagine can also create short videos with sound or turn photos into videos.

The official Google Play app offers AI chat, web and X search, document and image analysis, voice conversations, and image and video generation. Voice conversations let you speak with Grok rather than type every request. The feature can make a hands-free exchange more convenient when you are away from a keyboard.

For a complicated file or code task, ask for a specific output, such as a short summary or a line-by-line explanation.

How Much Does Grok Cost, and What Happens When Usage Runs Out?

Grok’s Free plan costs $0 per month, while its paid plans range from $8 to $200 per month. Each plan offers a different level of usage or model access. Choose based on your workload, not just the feature names. Included AI usage is shared across several Grok products and refreshes weekly.

The AI usage pool covers Chat, Imagine, Voice, and Bot. The allowance varies by product, so one activity may use it at a different rate than another. Check the remaining usage in settings before planning a longer session or repeated image-generation requests.

When included usage runs out, you can buy a top-up or wait for the weekly allowance to refresh. A top-up can help when you need more access right away; waiting works if the task can pause. The model version and product affect which features you can use within your allowance.

Subscriptions are sold directly through the official X Subscription website. Check the official X Subscription website before subscribing, because purchases from other sources may be suspended or terminated.

How Do You Manage Sensitive Content and Personal Data?

Spicy mode is an opt-in, R-rated setting, not a way to generate explicit sexual content. You can enable it only when you meet its age, subscription, region, and settings conditions. It is not an uncensored generator, and it blocks several kinds of prohibited material. You must be 18 or older and have a paid subscription in a supported region.

Enable Spicy mode only if you meet its conditions

Turn on “Display sensitive media” under Content Preferences and “Allow sensitive media generation” under Imagine Settings. Both settings must be enabled, along with the age, subscription, and supported-region requirements. Spicy mode is available through the iOS and Android apps and is hidden on the web in most regions.

The Spicy mode content rules block explicit sexual acts, sexual imagery of minors, real-person deepfakes, and non-consensual scenarios. The R-rated tier does not remove those limits. If either sensitive-content setting is off, the required settings condition is no longer met.

Understand what account and conversation data may be involved

Signing in with X may authorize sharing profile details, date of birth, account and location information, preferences, post history, usage data, and Grok on X conversation history. SpaceXSI’s privacy policy covers account information such as your name, contact information, credentials, and date of birth.

Your prompts and other inputs can include files, images, audio, voice, or video. Those materials may contain personal information that can appear in Grok’s output. The SpaceXSI privacy policy does not cover Grok used on X; X’s Privacy Policy and Terms govern that use instead.

Before sharing a sensitive file or recording, check what personal details it contains and which service’s privacy terms apply.

How Do You Write Prompts That Get More Helpful Results?

A useful Grok prompt names the task, supplies context, and tells the assistant what kind of answer to return. Specific requests help the model focus on the information you care about. A narrower request helps keep the response on task.

Use this checklist before sending a prompt:

• State the task you want Grok to complete.
• Provide relevant context or source material, such as X posts or an uploaded file.
• Set constraints, including length, tone, or reading level.
• Name the output format, such as a list, summary, or explanation.

Keep one prompt focused on one task instead of bundling unrelated requests.

For example, ask: “Summarize current public X posts about the city’s new bike lanes as three dated points.” This names the source, topic, and format. For code, try: “Explain this supplied error in plain English and suggest one fix.” That request sets a clear task and limits the response.

Specific context can include which posts to focus on or which part of an uploaded file matters. Constraints help Grok choose the right language and amount of detail. Check important claims before acting on them, especially when the answer affects a decision or a workflow.

For decisions that matter, verify the response against the original information before relying on it.

Conclusion

The simplest way to begin is to choose one task and give Grok enough context to answer it. Start with the route that fits what you want to do: a direct chat, a question tied to public posts, or an integration for your own software. Then write a focused prompt that names the useful details and the response you need.

You do not need a complicated request for a first try. Ask for a short summary, a plain-language explanation, or another low-stakes result. Review the answer and adjust your next prompt if you need a different format or level of detail.

Open Grok on the web or in an app, sign in, and try one clear, low-stakes request.
