Create a custom Gem in the Gemini web app by giving it a name, clear instructions for a recurring task, and—if useful—reference files under Knowledge. Test it in Preview, refine the instructions, then select Save. Previewing alone does not save the Gem.
How to create a Gem in Gemini
- Open the Gemini web app and go to Gems.
- Select New Gem.
- Enter a name that identifies the recurring job, such as “Meeting Notes Formatter” or “Product Description Reviewer.”
- Write instructions describing what the Gem should do each time. A useful structure is role, task, context, and output format.
- Optionally add reference material under Knowledge. See the file setup details below.
- Use Preview with a representative task, check the result, and revise the instructions as needed.
- Select Save when you are satisfied. Google cautions that Preview does not automatically save the Gem.
Google’s creation and saving steps are documented in its Gemini Apps Help guide to creating and managing Gems.
How to write instructions for repeatable work
Describe the recurring job, not just one example request. Google recommends making instructions clear and detailed, and suggests covering four dimensions:
- Persona: the role the Gem should take and how it should respond.
- Task: the recurring work it should perform or the output it should create.
- Context: background, audience, constraints, and any relevant reference material.
- Format: the structure or presentation the response should follow.
For example, adapt this template to your workflow:
Role: [what the Gem should act as]. Task: [the recurring job]. Context: [audience, constraints, and reference material]. Output: [format, length, and required sections]. If key information is missing, ask before assuming.

Google also says you can ask Gemini to rewrite or expand a short initial instruction. Treat the result as a draft: review and edit it so its role, constraints, and output requirements match your needs before saving. These instructions can guide a workflow, but Google does not promise identical responses or perfect compliance on every run. See its Gems setup guidance.
How to test and refine a Gem
- Choose a realistic example of the recurring task, including the kind of input the Gem will receive in ordinary use.
- Run it in Preview and compare the response with your requirements: Did it complete the task, respect the context, and use the requested format?
- If something is missing or inconsistent, revise the instructions. Make the relevant requirement explicit rather than adding a one-off correction to the test prompt.
- Preview again, then select Save to keep the revised Gem.
Preview is a practical check of the setup, not a guarantee that future answers will be identical. If a Gem’s response varies, refine the instructions and continue to review important outputs.

Should you add files to a Gem?
Knowledge files are optional. Add them when the recurring task depends on reference material—for example, a maintained style guide or process document. If the task can be described fully in the instructions and does not need shared reference material, you can start without files.
| Setup | When it fits | What to consider |
|---|---|---|
| Instructions only | The task’s rules and context are concise and stable enough to state in the Gem instructions. | Less file setup and maintenance; revise the instructions when the workflow changes. |
| Instructions plus Knowledge files | The task relies on reference material that is useful to keep separate from the instructions. | More setup and source maintenance; check that the Gem has access to the relevant files. |
Google documents adding files from your device or Google Drive under Knowledge. For Drive files, Google says Keep Activity must be on and Google Workspace must be connected to Gemini Apps. It also says the most recent version of a Drive file is used, so updating a maintained document can update the material available to the Gem. On a computer, Google’s help also describes adding a NotebookLM notebook. Details are in Google’s Gems guide and computer guide for using Gems.

Google does not publish comparative measurements showing that adding knowledge files improves a Gem’s output. Choose based on whether the task needs reference material, the effort required to maintain it, and whether you have the needed Drive access.
Where you can create and use a Gem
Google says Gems created in the web app appear in the Gemini mobile app and the Workspace side panel. Its help also says custom Gems can only be created, edited, or deleted in the Gemini web app, while saved Gems can be used on web and mobile. In other words, you can use a saved Gem from supported clients, but do not expect every management control to be available in each one. Check Google’s computer instructions for using Gems for client-specific details.

Google’s announced Gems-to-Skills transition
As of October 3, 2026, Google’s help page titled About the transition from Gems to skills says Gems will transition to Skills starting in November 2026. Google says it will automatically recreate Gems as Skills when Gems go away and also describes a manual recreation procedure. This is an announced future change, not a completed transition as of that date; check Google’s current help before following this tutorial because rollout timing or details may change.
Eligibility and account caveats
Google’s cited instructions do not comprehensively establish subscription requirements, availability in every country, or organization-specific administrator restrictions. If you do not see Gems or cannot connect a Drive file, check the current Gemini help and any applicable organization settings for your account rather than assuming the feature is universally available.
