Yes, Grok is free to use. xAI says Grok is free to try on the web and in the iOS and Android apps, with limited free access depending on where you live, and SuperGrok adds higher limits, priority access and multi-agent reasoning.
Grok is xAI's AI assistant, and you can reach it three ways: the grok.com website, the Grok mobile apps, and inside X. None of them asks you to upgrade before you can start chatting. What changes on the free version is how much you can use it, and xAI is careful not to publish a fixed number of free messages. Here's what the free version gives you, what SuperGrok adds, and the two settings I'd check before you put any business work through it.
What free Grok lets you do
According to xAI's consumer FAQs, Grok handles question answering by voice and text, information retrieval, creative writing, image generation, image editing, image and video understanding, and coding help. The free version gives you access to those features, with usage limits.
- Chat on grok.com or in the apps for iOS and Android.
- Use Grok inside X, which X says is available in every country where X itself is available.
- Generate and edit images, subject to the free usage limits.
- Choose personas that change how Grok answers you.
- Keep a conversation history you can search and delete.
Free Grok vs SuperGrok
xAI doesn't publish exact message caps on its product page. It describes the difference like this:
| Feature | Free Grok | SuperGrok |
|---|---|---|
| Web and app access | Yes | Yes |
| Usage limits | Limited, and access varies by location | Higher limits |
| Priority access | No | Yes |
| Multi-agent reasoning | No | Yes |
| You own your outputs | Yes | Yes |
The honest reading is that free Grok is fine for everyday questions and a few images, and SuperGrok is for people who hit the limit regularly or want the heavier reasoning mode.
The catch: your chats can train Grok
This is the part worth knowing before you paste anything in. xAI's FAQ says it may use your content and interactions, including prompts, searches and the materials you submit, along with Grok's responses, to train its models. You control whether that happens through the data controls in the app and on grok.com.
On X, the help centre says X may share your public X data, plus your interactions, inputs and results with Grok, with xAI to train and fine-tune Grok and other models. You can switch that off in your X privacy settings. xAI also notes that a limited number of authorised staff may review conversations for purposes such as improving the model and investigating misuse.
X's own help page goes further and asks you not to share personal data or sensitive and confidential information in conversations with Grok. For a small business, that means client names, contracts and anything under a confidentiality agreement stay out of the free chat.
Can you use free Grok images for business?
Yes. xAI's FAQ says you own both your inputs and Grok's outputs, including generated images, and you're free to use them as you wish, including for commercial use. There's one courtesy request attached: xAI asks you to attribute generated work to Grok, as set out in its brand guidelines.
If you're making social graphics with it, my collection of Grok Imagine prompts is a good place to start, so you get usable images inside the free allowance rather than burning it on retries.
How to start using Grok for free
- Go to grok.com or download the Grok app from the App Store or Google Play.
- Sign in and confirm you're at least 13. xAI says users aged 13 to 17 need a parent or guardian's permission.
- Open Settings and find the data controls, then decide whether your content can be used for training.
- If you use Grok on X, check the matching setting in your X privacy settings too.
- Start chatting, and keep anything confidential out of your prompts.
Managing and deleting your Grok history
Your past conversations stay in your history. On iOS, xAI says you tap your profile picture at the top left to open it. On grok.com, the history icon sits at the top right of the screen.
To delete a single conversation on grok.com, open the history page and select the trash button next to it. To delete every conversation, or your whole account, go to Settings and choose the matching option. It's worth doing a clear-out if you've tested Grok with anything work related.

Where Grok's answers need checking
X's help page describes Grok as able to confidently give factually incorrect information, missummarise or miss context, and encourages you to verify what it tells you. Personas matter too. xAI's FAQ explains that some modes, such as the one it calls unhinged, can produce objectionable or offensive replies. For anything that'll be read by a client, stick to the standard mode and fact-check the output.

Who free Grok suits
Free Grok suits business owners who want a second AI assistant for quick research, brainstorming and the odd image, especially if they already use X. It's a weaker fit for confidential work or heavy daily use, because the limits aren't published and the training setting needs managing.
My verdict: Grok is free and capable enough for everyday tasks. Turn off training in the data controls first, keep client details out of it, and only think about SuperGrok if you keep hitting the limit.
