How to Create Gemini Gems: Step-by-Step Guide with 12 Work Examples

A Gemini Gem is a version of Gemini that you set up once for a specific job, such as drafting job descriptions, reviewing sales emails or summarising reports, so you never have to re-type the same long prompt. This guide shows how to create Gemini Gems step by step, how to write instructions that make a Gem behave consistently, how to share it with your team, and gives you twelve examples you can adapt today.

What a Gemini Gem is, and when it is worth building one

A Gem is a saved set of instructions, plus optional reference files, that turns Gemini into a specialist for one task. Instead of starting each chat with “You are an HR expert, use this template, write in this format…”, you open your Gem and simply paste the rough notes.

A Gem is worth building when three things are true: you do the task often, the instructions are long enough to be annoying to repeat, and the output should look the same every time. A weekly report, a job description, a sales follow-up, a policy answer: all good candidates. A one-off question is not.

Google makes Gems available to Gemini users aged 18 and over, on the web and in the Gemini mobile app. Google announced in 2025 that Gems no longer need a paid subscription. Work accounts depend on what your Google Workspace admin has switched on.

Five steps to create a Gemini Gem: Explore Gems, New Gem, instructions, knowledge files, preview and save
Creating a Gem takes five steps and about ten minutes the first time.

How to create a Gemini Gem, step by step

  1. Open Gemini at gemini.google.com and sign in with the account you will use the Gem on (personal or work).
  2. Select Explore Gems in the sidebar, then New Gem.
  3. Name it specifically. “JD writer: Mumbai roles” is better than “HR helper”. You will thank yourself when you have ten Gems.
  4. Write the instructions using the four-part method below.
  5. Add knowledge files if the Gem needs reference material, such as a template, a policy or a price list.
  6. Test in the preview panel on the right. Paste a real example of the input you will give it and see what comes back.
  7. Refine and save. Most Gems need two or three rounds of instruction edits before they are reliable.

Google also offers premade Gems, such as Brainstormer, Coding partner and Writing editor. Opening one and reading its instructions is a quick way to see what good instructions look like.

Writing instructions that work: persona, task, context, format

Google’s own guidance for Gem instructions uses four building blocks. They are worth following closely, because vague instructions are the main reason Gems give inconsistent answers.

Example Gemini Gem instructions using persona, task, context and format
The same four parts work for almost any Gem. This example builds a job-description writer.
  • Persona: who the Gem is and how it should sound. “A senior HR business partner, warm and precise” produces very different writing from “a recruiter”.
  • Task: exactly what it produces every time. One Gem, one job.
  • Context: what it must know before it starts, such as your company, your audience and the files it should use.
  • Format: how the output should look: headings, length, bullet points, tables, tone.

Three additions make a big difference in practice:

  1. Tell it what to do when information is missing. “If the notes don’t mention a salary range, write [SALARY RANGE: CONFIRM] instead of guessing.”
  2. Give it one example of good output, either in the instructions or as a knowledge file.
  3. List what it must never do, such as invent figures, promise delivery dates or mention competitors by name.

If you already use detailed prompts with Gemini, a Gem is simply the best of those prompts, saved. Our collection of Gemini prompts is a useful source of starting points; many of them become good Gems with a persona and a format added.

Adding knowledge files: what to upload and what to leave out

Under Knowledge, you can upload reference files the Gem should use: Google Docs and Sheets, Word, PDF, Excel and CSV files, among others. Google’s Workspace update announcing the feature allowed up to 10 files per Gem.

What works well as knowledge:

  • Templates: your JD format, report layout or proposal structure.
  • Reference material: product sheets, a price list, a style guide, an FAQ.
  • Good examples: two or three past outputs you were happy with.

What to leave out: personal data about customers or employees, confidential financials, and anything your company has not cleared for AI tools. If you update a reference file, test the Gem again, because its answers depend on what it can read.

Test, refine and keep a version note

Before you rely on a Gem, test it with:

  1. A normal input, such as a typical set of notes.
  2. A messy input, with missing details, to see whether it flags gaps or invents them.
  3. An input it should refuse or question, such as a request outside its job.

Each time you change the instructions, add a line at the end such as “Version 3, 8 Oct: added rule on salary ranges”. When a colleague says the Gem has started behaving differently, you’ll know why.

12 Gemini Gem examples for work

Here are twelve Gems that work well in Indian and UAE offices. Each line is the core of the instructions; add your own persona details, files and format.

1. JD writer (HR)
Turns a manager’s notes into a job description in your template, flagging missing salary, location or reporting line.
2. Interview question builder (HR)
Creates role-specific questions with what a strong and weak answer looks like, from the JD you paste.
3. Policy answerer (HR)
Answers employee questions from your uploaded handbook, quotes the section, and says when HR must decide.
4. Sales follow-up writer
Turns meeting notes into a short follow-up email with next steps, in your company’s tone.
5. Proposal first draft
Builds a proposal from the client brief, using your uploaded capability sheet and past proposals.
6. Objection handler
Suggests honest responses to common objections, using only claims from your product sheet.
7. Variance commentary (Finance)
Writes month-end commentary from the figures you paste, asking for reasons rather than inventing them.
8. Vendor email drafter (Procurement)
Drafts polite, firm emails for delays, quote requests and clarifications, in the right formality.
9. Contract summariser (Legal support)
Lists parties, term, payment, termination and liability from a pasted contract, with clause numbers.
10. Meeting minutes formatter
Turns notes or a transcript into decisions, actions with owners and open questions.
11. Brand voice editor
Rewrites any draft into your brand’s tone using your uploaded style guide and banned-words list.
12. Bilingual message checker
Checks that an English and Arabic, or English and Hindi, version say the same thing, and lists differences for a fluent reviewer.

Here is one complete set of instructions you can copy and adapt:

Name: Sales follow-up writer
Persona: You are an experienced B2B account manager. You write short, warm, professional emails. You never oversell.
Task: Turn my rough meeting notes into a follow-up email to the client.
Context: Our services are described in the attached capability sheet. Clients are mid-size companies in India and the UAE. Use only claims from the capability sheet.
Format: Subject line; greeting; two lines thanking them and recapping the need; three bullet points on agreed next steps with dates; one-line close. Under 150 words.
Rules: If a date or owner is missing, write [CONFIRM]. Never mention pricing unless it is in the notes.

Building Gems for a whole team?

A good Gem saves one person time; a set of well-designed Gems changes how a department works. In Gemini training sessions, teams build and test Gems for their own recurring tasks and agree how they are shared and maintained.

How to share a Gem with your team

Once a Gem works, sharing it means everyone gets the same quality. According to Google’s help centre:

  1. Open the sidebar, go to Gems, and select Share next to your Gem.
  2. Enter colleagues’ email addresses and choose a permission level.
  3. Optionally set an expiry date for access, or add a message.
  4. Select Send. You can also copy a link to share.

Viewers can use the Gem and see its contents. Editors can also change its instructions and files, and share it further. Shared Gems are saved in a new Google Drive folder, and you can transfer ownership to someone who already has access. Be careful with that last option: the new owner can remove your access.

On work accounts, your administrator may have turned Gem sharing off. If you see “Your organization has disabled Gem sharing”, that is a company setting, not a bug.

A tip for teams: keep one person as the owner of each shared Gem, give most colleagues Viewer access, and collect suggestions rather than letting everyone edit. Gems drift quickly when five people tweak the instructions.

Using Gems on your phone

Gems work in the Gemini mobile app as well as on the web, which is handy for quick jobs: dictating meeting notes into your minutes Gem in the car, or checking a policy answer between meetings. Longer instruction editing is easier on a laptop.

Gems vs ChatGPT Projects vs NotebookLM

People often ask which tool to use. They overlap, but each has a sweet spot:

A quick way to choose between three tools that look similar but suit different jobs.

If your main need is answers that stay strictly within your documents, with citations, NotebookLM (now called Gemini Notebook) is the better fit. Our guide on how to use NotebookLM for work covers it. If you want a reusable assistant for a repeat task, build a Gem.

Common Gem mistakes, and how to fix them

  • One Gem for everything. “Marketing helper” Gems produce average work. Split them: one for social posts, one for email, one for briefs.
  • No format instruction. Without one, output length and structure change every time.
  • No rule for missing information. The Gem fills gaps with plausible guesses. Tell it to flag them instead.
  • Uploading too much. A few focused files beat a pile of loosely related ones.
  • Never revisiting it. Review each shared Gem every quarter, especially if your templates or policies have changed.

A privacy checklist for company Gems

Before you build or share a Gem at work:

  • Use your work account if your company has approved Gemini, not a personal Gmail account.
  • Keep customer and employee personal data out of knowledge files unless your policy allows it.
  • Share with named colleagues or your organisation, not “anyone with the link”, for anything internal.
  • Remember that Viewers can see the instructions and files, so don’t put confidential details in them.
  • If your company does not yet have rules on AI tools, a short AI usage policy for employees is a good place to start.

Start with one Gem for the task you repeat most this week. Once it saves you time, the second and third come easily.

Questions people ask

Google announced in 2025 that Gems are available to Gemini users aged 18 and over without a paid subscription. On work accounts, availability depends on your Google Workspace settings.
Google’s update introducing knowledge files allowed up to 10 files per Gem, including Google Docs and Sheets, Word, PDF, Excel and CSV files. Check the current Gemini help centre for limits on your account.
Yes. Open Gems in the sidebar, select Share, enter email addresses and choose Viewer or Editor. You can set expiry dates or share a link. Work administrators can disable Gem sharing for an organisation.
Google’s help centre covers Gems on both the Gemini web app and the mobile app. Writing long instructions is usually easier on a laptop, but you can use your Gems on your phone.
A prompt is a one-time instruction in a chat. A Gem saves your best instructions, and optional reference files, so you get the same quality every time without re-typing them.
Yes. On work accounts, administrators control sharing, and you may see a message that your organisation has disabled Gem sharing.
If your team works in Google Workspace and Gemini, a Gem is the natural choice. OpenAI has announced that custom GPTs are being retired in favour of newer features, so for new builds on ChatGPT check OpenAI’s current guidance.
Usually because the instructions don’t specify the format, length or what to do when information is missing. Add those, include one example of good output, and test again.
