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

Grok is an AI assistant you can use to ask questions, work with information, and create content. If you have an account on X or xAI, you can start a conversation and shape the result through follow-up requests. A clear first step makes the tool easier to use, whether you need a quick answer or help with a longer task.

Choose a chat route, tell Grok what you need, and refine its answer if the first version misses the mark. Available features and usage limits depend on your access route and plan. Your best results come from treating the exchange as a conversation, not a one-shot search. Add details when they matter, and ask for a different format when useful.

Key Takeaways

• Grok can answer questions, work with information, and create content.
• Choose the chat route that fits your task.
• Give Grok a clear request, then refine its answer.
• Features and limits vary by access route and plan.
• A specific request and a follow-up correction are usually more useful than a vague first prompt.

What Is Grok, and What Can It Do?

Grok is xAI’s conversational assistant, built to respond to questions and help with tasks such as writing and problem-solving. Grok began on X as a feature in late 2023. xAI, the company founded by Elon Musk, has since developed it into a family of models for different kinds of work.

You can use Grok to draft text, brainstorm ideas, explain information, and interpret images with supported models. Its personality can include a conversational tone and humor, though the experience depends on the selected version and feature. Grok models do not all support the same capabilities.

Grok’s supported features depend on the model you select, so check the options shown in your account.

The model family includes reasoning models for complex tasks, faster non-reasoning models for direct responses, and vision-capable variants that can process images. A model may also offer tools that help it complete particular tasks. The exact combination of abilities differs across models and products.

For a writing task, Grok can help shape a draft or suggest a new approach. For an image question, choose a vision-capable option when your account offers one. Choose the model or feature offered in your account for the task you have in mind.

How to Use X AI Across X, grok.com, and the Apps

You can access Grok through X, grok.com, or the dedicated iOS and Android apps. Grok is available on all four routes, giving you a choice between a social platform and a focused chat experience. To get Grok AI, open one of these official options and sign in with your xAI account where prompted.

Grok.com is the standalone AI website for chat away from X’s feed. The Grok AI website suits focused sessions, while X puts the assistant beside posts and feed activity. X and grok.com share the same xAI account, model, subscription, and conversation history.

Grok’s consumer-facing website and apps are available on iOS and Android. Grok 4.5 became available on grok.com, X, iOS, and Android on July 23, 2026. The same account details and conversation history follow you between X and grok.com, so you can continue there without starting from scratch.

Use Grok on X when the post or trend itself matters, and grok.com when you want to work away from the feed.

How Do You Get Better Answers from Grok?

A useful Grok prompt says what you want done, what context matters, and what form the answer should take. Specific details help the model avoid guessing about your goal. Enter a clear request in the chat, then keep refining it in the conversation.

Give Grok the task, background, format, and limits that shape a useful answer. This approach works for writing, brainstorming, coding questions, and problem-solving. Some Grok models also support tool calling, structured outputs, and large-context processing, depending on the selected model.

Give Grok a clear task and useful context

Start by naming the work, then add only the background Grok needs. Specify the format you want, such as an email, a short list, or a step-by-step explanation. State limits or criteria, including length, audience, tone, or facts the answer must preserve.

• Task: say what Grok should do.
• Context: include the relevant background or supplied information.
• Output format: name the form, length, or structure you want.
• Limits or criteria: set the tone, audience, rules, or points to keep.

For example, paste meeting notes and ask: “Turn these notes into a concise email to my team. Keep the deadline and action items.” This gives Grok the source text, audience, and purpose, rather than asking for an email without enough information.

Refine the answer with follow-up instructions

Read the first answer, identify what needs changing, and give one direct correction. You could follow up with, “Make the tone warmer, but keep the same action items.” For a long draft, ask for a shorter version while naming the details that must remain.

Each follow-up adds direction without requiring you to repeat the whole task. If the answer is too formal, too long, or too general, name that issue plainly. You can also ask Grok to show its result as a table or a numbered sequence when that format is easier to use.

Grok can help organize information, but a polished response is not proof that every detail is right. Check important claims against reliable information before relying on them.

How to Use Grok with X Posts and Trends

If your question depends on what people are posting right now, Grok on X can work with public posts and feed context. That live context makes it useful for a specific post, a thread, a trend, or a fast-moving discussion. It can help you see what people are discussing without treating every post as verified fact.

Public-post context shows current discussion, not proof that a claim is true. To interact with Grok about a particular conversation, start from the relevant content on X and make your question specific. Ask for a summary or analysis, and name what you want checked.

1. Open the relevant public post or thread on X.
2. Invoke Grok from X using the available entry point.
3. Ask for a focused summary or analysis, and identify what needs checking.

For example, ask Grok to summarize the main points in a thread and separate direct claims from replies or opinions. That can make a long conversation easier to follow. A trend question can help you understand the topic people are discussing, but it cannot establish the accuracy of a claim by itself.

Use the original post to inspect its wording and context, especially when a summary leaves out a detail. For a consequential claim, check the original post and corroborate it beyond the conversation.

How to Generate Images and Enable Spicy Mode

Grok Imagine can create an image from a description, but Spicy mode is a restricted setting rather than a way to remove moderation. Describe the subject, style, and composition you want, then request changes in follow-up instructions. Spicy mode is for users aged 18 or older and remains subject to content limits.

Imagine works best when your description names the key visual details, such as the subject’s position or the scene’s lighting. You can ask for a different style, framing, or background after seeing a result. Image generation and video generation use separate moderation, so animation can have a different outcome.

Create and refine an image in Imagine

Enter a description of the image you want, including its subject, style, and composition. For example, name whether the subject is centered, where the light falls, and what appears in the background. These details give Imagine more direction than a short request such as “make a portrait.”

When the first result is close but not right, request one change at a time. You might ask for softer lighting or a wider composition while keeping the same subject. This makes it easier to judge whether the update matches your intent.

Enable Spicy mode within its limits

In the Grok app, open Profile → Settings → Privacy and Safety. Confirm a birth year showing you are 18 or older, then enable “Display sensitive media” and “Allow sensitive media generation.” Finally, choose Spicy in Imagine.

Access requires a paid subscription, age verification, a supported region, and an age of 18 or older. In 2026, Spicy mode is available through the iOS and Android apps, and is hidden on grok.com in most regions. The in-app settings do not bypass these access conditions.

Complete the setup with these three actions:

• Confirm an 18-or-older birth year in your profile.
• Enable both sensitive-media settings in Privacy and Safety.
• Select Spicy in Imagine.

Spicy mode allows suggestive poses, partial nudity, intimate framing, and mature themes within an R-rated-movie content envelope. It blocks explicit sexual acts, anyone under 18 or appearing under 18, real-person deepfakes, and non-consensual scenarios.

An image that generates successfully may still be blocked when you try to animate it because video uses separate moderation. If an image cannot be animated, treat that as a separate video moderation decision, not proof that the image itself was invalid.

What Do Grok Plans Cost, and How Do Limits Work?

Grok’s October 2026 plans range from Free at $0 to Ultra at $200 per month, with paid tiers offering larger weekly pools. Plan details include different allowances and video access. A weekly usage pool is the shared weekly allowance that paid users draw from across Grok’s different products.

Paid users share one weekly usage pool across Chat, Imagine, Voice, and Build. Image and video generation, plus long coding or agent runs, consume substantially more than ordinary chat. The October 2026 prices and allowances are:

The October 2026 plan details set the Free tier at limited daily access to Chat, Imagine, and Build, with no video generation. Plus provides the base paid pool, while Premium, Super, and Ultra offer larger amounts. The pool reset schedule appears in Settings under Usage.

Open Settings → Usage to see product-level use, your reset date and time, and any Extra Usage Credits balance. When a paid weekly limit is reached, paid features pause until reset. Free-tier Chat and Voice limits remain available after that point.

Older SuperGrok plans in 2026 offered Extra Usage Credits on the web from $5; credits expire one year after purchase. xAI announced The X Subscription on October 12, 2026, without setting terms in this plan comparison. Check the Usage tab’s reset time before deciding whether to wait for the next pool or change how you use Grok.

How Do You Use the Grok API and Manage Data?

Developers use the xAI API with separate billing, while personal users can manage X data sharing in X’s privacy settings. For an application, create an API key in the xAI Console and use the API to connect xAI models with your tools. API usage is billed separately from a consumer plan’s weekly usage pool.

The image-generation API accepts 1-10 images per request and supports 1k or 2k resolution. When you omit the resolution, the default is 1k. Supported aspect ratios include 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 2:1, 1:2, 19.5:9, 9:19.5, 20:9, 9:20, 21:9, 5:2, and auto.

Generated images return temporary hosted URLs by default. Download or process the images promptly because those URLs are temporary.

To limit X data sharing, open Privacy and safety and find “Grok & Third-party Collaborators” or “Data sharing.” Turning off X data sharing limits future sharing, but does not automatically remove data already collected or shared.

Grok Private Chat conversations are not saved to history and are deleted within about 30 days, subject to legal, safety, or compliance retention.

For formal data access, deletion, or portability requests, submit a request through the xAI Privacy Portal. Private Chat’s history behavior is different from those formal requests. Keep your API key private, and use only the data your application needs for its task.

Conclusion

The simplest way to get started is to match Grok’s setting to the task you want to do. X works well for questions about public posts, while grok.com gives you focused chat away from the feed.

Open the route that fits your goal, then try a prompt that names the task and desired format. Try one specific prompt, then refine the answer with a clear follow-up.
