Step by step

  1. Open Manage Prompts

    Click the round button in the bottom-right corner. In the AI Toolbox list, click Manage Prompts.

    If you don't see Manage Prompts, open Settings in the same list and switch on Prompt tools.

    You should see: A window called Manage Prompts. If it is empty, it says No saved prompts yet.

  2. Create a prompt

    Click New prompt. Type a short Name, for example Summarize, and the full text in the Prompt box.

    For parts that change each time, type a word in double curly braces, like {{topic}}. AI Toolbox asks you to fill it in when you use the prompt.

    You should see: The two boxes Name and Prompt, and an Add button.

  3. Save it

    Click Add. On the free plan, a bar shows how many of your 2 prompts you have used.

    You should see: Your prompt in the list with Insert, Copy, Edit and Delete buttons.

  4. Type // in the Grok message box

    Close the window. Click in Grok's message box, where you normally type. Type // at the start of the box or after a space.

    A list of your saved prompts opens. Type a word after // to narrow the list, for example //sum.

    You should see: A list of your saved prompts floating just above the message box.

  5. Pick a prompt

    Click a prompt, or use the arrow keys and press Enter. It replaces the // you typed. Anything else you already wrote stays.

    If the prompt has words in curly braces, a small window with the prompt's name opens first and asks for each one. Fill in each box and click Insert.

    You should see: The prompt text in Grok's message box, ready to send.

    You can also click Insert next to a prompt in Manage Prompts. The prompt goes after anything you already typed.

That's it. You have finished every tutorial in this section.

If something doesn't look right

Typing // does nothing

Type // at the very start of the box or after a space. It does not open in the middle of a word or a web address. Also check that Prompt tools is on: open Settings from the AI Toolbox list and look under Prompts.

Clicking New prompt opens an upgrade window

You already have 2 saved prompts, which is the free limit. Delete one you no longer need, or upgrade to Premium for unlimited prompts.

It says Name and prompt text are both required.

Both boxes need something in them. Give the prompt a short name and paste the prompt text, then click Add.

My prompts are not on my other computer

Prompts are saved to your AI Toolbox account and follow your X account. If Keep my Prompt Library on this device is on in Settings, they stay on this computer only. Switch it off to sync them again.

Free and Premium

The free plan saves 2 prompts. Premium saves unlimited prompts. The same prompts appear on grok.com and on X.

  • Free: 2 saved prompts.
  • Premium: unlimited saved prompts.
  • Prompts are the same on grok.com and X, and are shared with AI Toolbox on ChatGPT, Claude and Gemini.

What Grok does on its own

Grok lets you set custom instructions that shape how it answers you. That is one standing instruction that applies to your chats.

Saved prompts in AI Toolbox are different: a list of ready-made messages you pick from with //, each used only when you choose it, with blanks you fill in each time.

How do I save prompts in Grok?

Install AI Toolbox, click the round button in the bottom-right corner of grok.com or x.com/i/grok and choose Manage Prompts. Click New prompt, give it a name, paste the text and click Add. Then type // in the Grok message box and pick the prompt to insert it.

How many prompts can I save for free?

The free AI Toolbox plan saves 2 prompts for Grok. Premium saves unlimited prompts. Your saved prompts are tied to your AI Toolbox account, so the same list appears on grok.com, on Grok inside X, and on ChatGPT, Claude and Gemini when you use AI Toolbox there.

What does // do in Grok?

With AI Toolbox installed, typing // in the Grok message box opens a list of your saved prompts. Type a word after // to filter the list, then click a prompt or press Enter. The prompt replaces the // you typed and keeps the rest of your message.

Can Grok prompts have blanks I fill in each time?

Yes. In AI Toolbox, put a word in double curly braces in your prompt, such as {{topic}} or {{language}}. When you insert the prompt with // or the Insert button, a small window asks for each value, then puts the finished prompt into the Grok message box.

Do my saved prompts work on Grok inside X?

Yes. AI Toolbox saved prompts and the // shortcut work on x.com/i/grok and on grok.com. The prompts are saved to your account, so you see the same list on both sites. The shortcut only works in Grok's message box, not in the box for writing posts on X.
