A Gem is a saved version of Gemini with your own instructions, for jobs you do again and again, such as replying to customer enquiries in your company's tone or checking quotations against a price list. Gems are included in the Gemini app on all Business and Enterprise plans.

## Create a Gem

Build Gems on your computer at [gemini.google.com](https://gemini.google.com), signed in with your work account.

1. Click **Settings** (the gear icon at the bottom left), then **Gems**. The **Gem manager** opens.

2. Click **New Gem**.

3. Enter a **Name** and the **Instructions**. For example: "You help our sales team reply to customer enquiries. Write in polite, simple English, keep replies under 150 words and always end with our office phone number." You can also add a short **Description** so colleagues know what the Gem is for, and pick a **Default tool** if you want the Gem to always start with one.

4. Optional: under **Knowledge**, click the **+** in the **Add files for your Gem to reference** box to upload a price list or product sheet, or add a file from Drive.

## Use a Gem

Your saved Gems appear in the Gemini app and in the Gemini side panel of Workspace apps.

1. Go to [gemini.google.com](https://gemini.google.com), click **Settings** (the gear icon at the bottom left), then **Gems**.
2. Under **My Gems**, pick the Gem.
3. Type your request and click **Submit**.

## Share a Gem with colleagues

Sharing saves everyone rebuilding the same assistant.

1. At [gemini.google.com](https://gemini.google.com), click **Settings** (the gear icon at the bottom left), then **Gems**.
2. Next to the Gem, click **Share**.
3. Enter your colleague's email and choose **Viewer** or **Editor**.
4. If the Gem uses uploaded files, choose whether to share those files too.
5. Click **Send** or **Share**.

Anyone with access can read the Gem's instructions and files, and editors can change or delete it. Shared Gems are stored in Google Drive, so your company's Drive sharing rules apply, including whether they can go outside the company.

## Common issues

### I cannot see Gems in the Gemini app on my phone. Why?

Work accounts cannot use Gems in the Gemini mobile app. Create and use them at gemini.google.com on your computer.

### A colleague shared a Gem with me but it is not in my list. Where is it?

Shared Gems are not added automatically. Open the link your colleague sent and use the Gem once; it then appears under My Gems.

### Why can I not share my Gem?

Your admin may have turned off Gem sharing. Admins find it in the Admin console under Generative AI > Gemini app > Sharing > Gem sharing.
