How to Save Prompts in Grok

When you are signed in, your past conversations are on the history page at grok.com/history, and its maker says history is synced between the web and the phone apps. A conversation held in Private Chat is not shown there and is deleted within 30 days.

Little is published about how Grok works. The pages at x.ai say where the history is, and not how to search it.

• Custom instructions are listed as a way to tailor responses to your style and needs. Where they are set and how long they can be is not on the pages at x.ai.
• Projects are workspaces you create and upload files to.
• Skills, added in May 2026, let you teach Grok a way of doing something once so that it keeps it across conversations. You make one by describing it in a chat, uploading a file or writing it out.
• Automations, added in July 2026, are instructions you write like a chat message, name and save. Grok then runs them on a schedule or when an email arrives, and each run is a fresh request.

An Automation is the nearest thing to a saved prompt, and it is built for a job that runs by itself. None of the pages at x.ai describes a list of prompts you pick from and put into the message box.

1. Install PromptTray from the Chrome Web Store and open Grok. You do not need an account: prompts are saved in your browser, and signing in later adds sync and a backup.
2. Type or paste the prompt in the message box. A Save button appears in the box as soon as there is text.
3. Press Save. PromptTray’s panel opens with the prompt filled in and a title taken from its first line. Shorten the title, pick a category, add tags if you want them, and press Save Prompt.

To use it again, press CtrlShiftKControl Shift K in any chat. Spotlight opens over the page: type a few letters of the title and press Enter. The prompt is in the message box, and nothing is sent until you send it.

Short prompts are the easiest to lose, because they never seem worth filing. These are worth it:

• Arguments for and against: “Give me the three strongest arguments for and against this claim: {claim}. Say which side has the better evidence.”
• Summarize the reaction: “Summarize the reaction to {event}: the main positions, who holds them, and what is still unknown.”
• Explain to a newcomer: “Explain {topic} to someone new to it in {length}, then list three things experts still argue about.”
• Draft a short post: “Draft a post about {subject} for {audience}, under 280 characters, with no hashtags. Give three versions.”

The words in curly braces are variables: PromptTray asks for them in a short form each time you insert the prompt. The guide to organizing AI prompts has the rules for titles, categories and tags.

The same library opens in 21 other apps, with the same shortcut. There is a guide like this one for ChatGPT, Claude, Gemini and Perplexity, and one on keeping one library across AI apps.

What this page says about Grok comes from its maker’s own pages, read on October 10, 2026: the Grok product page, the consumer FAQ, the announcement of skills, the announcement of Automations. Apps change, so check there if something here looks out of date.
