This page is designed to address questions from individual users of Grok who use the Grok mobile app (iOS or Android) or the Grok.com website.

If you are an xAI business or enterprise customer, please refer to our Enterprise FAQ. If you use Grok on the X platform, please see the X help center.

Note: xAI does not sell or issue tokens, coins, or crypto.

Who is xAI?

X.AI LLC ("xAI") is a United States-based company working on building artificial intelligence tools to accelerate human scientific discovery. We are guided by our mission to advance our collective understanding of the universe. xAI is a separate company from X Corp. ("X", previously Twitter).

What is Grok?

Grok is a conversational generative AI powered by xAI’s state-of-the-art Large Language Models. Grok performs a variety of tasks, including natural language processing, question answering (voice and text), information retrieval, creative writing, image generation, image editing, image and video understanding, and coding assistance.

You can make Grok your unique and entertaining companion. Grok is designed to answer almost any question with a touch of wit and humor, while providing helpful and insightful responses. You control how Grok responds to you by your choice of features (ex., choosing different personas) and by your choice of words and tones. For instance, you could instruct Grok to interact in a “fun” manner, so that Grok responds with jokes and humor like your funny uncle who juggles at the dinner table. As another example, you could instruct Grok to be “unhinged” which may result in Grok responding like an amateur stand-up comic who is still learning the craft – sometimes being objectionable, inappropriate, and offensive. As yet another example, you could instruct Grok to role-play as a wizard, and Grok would use wizardly language to describe magical situations. You direct the interaction with Grok. We hope you enjoy using Grok to stay informed and entertained.

Where can I use Grok?

Grok is available as a standalone conversational AI chatbot on your mobile phone (iOS) and (Android), and on your browser (grok.com). Depending on your location, limited free access and paid subscription plans with full features of Grok unlocked are available.

Grok is also available through the X platform. If you use Grok on X, please see the X help center for your questions. Your access on X is subject to the X Terms of Service and X Privacy Policy.

We also offer Grok services to business and enterprise customers, such as our Enterprise API. You can learn more about these services here.

Can children or minors use Grok?

Grok is not directed to children or minors under the age of 13. You must confirm that you are at least 13 years old to use Grok. If you are a teenager between the ages of 13 and 17 years old, you must have your parent or legal guardian’s permission to use Grok, and they must agree to our Terms of Service. While we have taken measures to limit undesirable training data and outputs, depending on the features that you choose to use, the Service could produce output that is not appropriate for all ages. For instance, if users choose certain features or choose to input suggestive or coarse language, Grok may respond with some dialogue that may involve coarse language, crude humor, sexual situations, or violence. We urge parents to exercise care in monitoring the use of Grok by their teenagers. Moreover, parents or guardians who choose to use certain features of Grok to aid in their interactions with their children, including regarding educational, enlightening, or entertaining discussions they have with their children, must make use of the relevant data controls in the Settings provided in the Grok apps to select the appropriate features and limitations for their needs.

How does Grok work?

Grok works by using advanced algorithms to understand and respond to your prompts. When you submit a prompt or search query, Grok interprets your words and other inputs based on natural language processing and patterns from its training data.

Grok has a unique feature that allows it to search public X posts and perform real-time web searches, allowing it to respond with up-to-date information and insights on a wide range of topics. You can also ask Grok to respond in the conversational style of your choosing. Plus, you can help improve Grok by rating its responses and submitting the reason why you believe a Grok response needs addressing.

You can interact with Grok by typing or, on iOS devices (and Android devices soon), speaking with Grok so that Grok speaks to you with its voice. You can also input your photos and ask Grok to edit them. You can also upload your documents and ask Grok to analyze them.

Can I see my history of conversations with Grok?

Yes, you can view your past conversations with Grok on your app. On iOS, tap on your profile picture at the top left corner of your screen, and you will be brought to the conversation history page. On Grok.com, go to the top right corner of your screen and click on the history (icon with three horizontal lines and a magnifying glass).

History icon

Yes, you control what you choose to share. You can share your Grok conversations with others: (i) on grok.com by clicking "Share" in the top right corner of your browser or the share icon below your conversation to create and copy a public share link, or (ii) on the Grok Apps by tapping the share icon under your conversation to create a public share link. From there, you also control where you share your Grok conversation.

Note: Any share link you generate will be accessible to anyone you choose to share the link with. For example, if you share the link publicly on a social media platform, it may be subject to indexing by a search engine (e.g., Google) just like any other publicly shared content.

Yes, you control what you share and how long it is shared. You can revoke access to any or all of your Grok conversation share links by logging into grok.com, navigating to grok.com/share-links, and clicking "Remove" next to the share link you no longer wish to share.

How can I make my conversations disappear?

You can also choose not to have your conversations saved by using “Private Chat.” To activate Private Chat, look at the top right corner of your screen for the ghost shaped icon. When using Private Chat, your conversation history will not be viewable to you and will be deleted from xAI systems within 30 days.

Who owns the inputs to and outputs from Grok?

You own the Inputs and Outputs. You are free to use Grok’s Outputs (including generated images) from your conversations as you wish, including for commercial use. You own Grok’s Outputs and you grant xAI certain use rights pursuant to xAI’s Consumer Terms. We do ask that you attribute the generated work to Grok as provided in xAI’s Brand Guidelines available on xAI’s legal website.

How has Grok been pre-trained?

Grok has primarily been pre-trained on a large corpus of publicly available information, including raw web page data, metadata extracts, and text extracts from the Internet. This data helps Grok learn about associations between words and updates its model weights to support natural language processing. In other words, the training data helps Grok learn about language and how to understand queries and respond to them in ways that humans can comprehend. Importantly, this training refines the model’s internal language structures. Once the training is done, the model does not reference or access the pre-training data.

Before using the training data, we apply quality filters and remove information that we do not want our models to learn from, such as violent content. We also apply security testing and evaluation measures. While Grok’s training data may incidentally include personal information that is publicly available (for example, information about politicians, celebrities, or other public figures), xAI takes steps to minimize the processing of personal and sensitive data for training purposes. For clarity, we do not actively seek out personal information to train our models or use personal information to build individual profiles.

Does Grok make mistakes?

On occasion, Grok may provide inaccurate or inappropriate information. Because Grok has been trained on publicly available information, which may sometimes include misleading or factually inaccurate information, Grok may at times include in its responses misleading or factually incorrect information based upon that public information. Grok may also reflect positive or negative views of politicians, celebrities, and other public figures. Also, because artificial intelligence is rapidly evolving and is probabilistic in nature, Grok may therefore sometimes generate responses that contain “hallucinations,” or that otherwise may not be suitable for your intended purpose. You should carefully consider and verify Grok’s responses before using them.

We constantly work to improve Grok. If you have feedback regarding a Grok response, we encourage you to send it to us.

Do humans view my conversations?

xAI may use automated content classifiers and safety tools to better understand how our services are used and to ensure our Terms of Service and Acceptable Use Policy are not being violated.

A limited number of our authorized personnel may review your conversations with Grok for specific business purposes, including improving model performance, investigating security incidents and potential misuse of our services, and complying with our legal obligations. For more information, see our Consumer Terms and Privacy Policy.

How can I use Grok responsibly?

We believe that everyone (aged 13 and above) should be free to use our services in a way that suits their needs, so long as they comply with the law, don’t harm themselves or others, and respect our guardrails. When using Grok, you must comply with our Acceptable Use Policy and the applicable Terms of Service for Consumers or Enterprise.

How does xAI handle my personal information?

For more information about xAI’s practices with respect to personal information, please see our Privacy Policy.

Does xAI use my content for model training?

We may use your content and interactions with Grok (e.g., prompts, searches, and other materials you submit) along with Grok’s responses to train our models. Specifically, this information helps our models better understand human language and communication and therefore ultimately provide more accurate, relevant, and engaging responses. It also helps boost the capabilities and safety of our models. You control whether your data is used for training Grok. The section below, “How do I select whether my content is used for model training,” explains how to control it.

To protect your privacy, please do not share any personal or sensitive information in your questions to Grok.

When using Private Chat, where available, your content and interactions are not used for model training. Similarly, we do not use content from our business and enterprise customers to improve our models. For more details, please refer to our Enterprise FAQ.
