What Are Gemini Gems? — AI Glossary

What it is: Gemini Gems are custom, reusable AI assistants you build inside Google Gemini. They’re Google’s direct equivalent of OpenAI’s Custom GPTs — pre-configured Gemini personas for specific tasks.
Who it’s for: Anyone using Gemini who repeats the same kind of task and wants a saved setup.
Best if: You want a plain-English explainer before creating your first Gem.
Skip if: You already use Gems regularly.

A Gem is a saved configuration of Gemini for a specific job — you give it a name, instructions, optional reference files, and (on Gemini Advanced) a starting model. Once saved, the Gem appears in your Gemini sidebar; click it and you’re already set up for that task without re-explaining the context. Google launched Gems in 2024 and has steadily expanded the feature ever since.

Google ships several pre-made Gems for common tasks — Writing Editor, Brainstormer, Career Guide, Coding Partner, Learning Coach — that you can use immediately without setup. Beyond those, you can create unlimited custom Gems tuned to your specific work.

What goes into a Gem

• Name and description: what this Gem does and when to use it.
• Instructions: plain-English rules for the Gem’s role, tone, output format, and constraints.
• Reference files (Gemini Advanced): documents the Gem can consult on every conversation — your style guide, a research corpus, product docs.
• Optional starter prompts: suggested questions users see when opening the Gem.

How to create or use a Gem

• To use a pre-made Gem: Go to gemini.google.com, click “Gems” in the sidebar, pick the one you want. Available on the free Gemini tier.
• To create your own Gem: Click “+ New Gem” in the Gems panel. Fill in the name, instructions, and (optionally) upload reference files. Save. The Gem appears in your sidebar.
• Requirements: Creating custom Gems is included with the free Gemini tier as of 2026, with deeper customization on Gemini Advanced ($20/month). Reference-file Gems require Gemini Advanced.
• Sharing: As of 2026 Gems are personal — there is no public store like the GPT Store. You can share a Gem by link inside Google Workspace.

How Gems compare to similar features

• vs. Custom GPTs: Custom GPTs are OpenAI’s equivalent inside ChatGPT, with a public store of 3M+ shared GPTs. Gems are Gemini-internal and personal, with smaller curated pre-made options.
• vs. Claude Skills: Claude Skills are Anthropic’s portable instruction packages that work across Claude products. Gems only work inside Gemini.
• vs. system prompts: A system prompt configures Gemini for one conversation. A Gem saves a reusable configuration that persists across all your sessions.
• vs. Workspace integrations: Gemini for Workspace plugs Gemini into Gmail/Docs/Sheets. Gems are saved configurations of Gemini; they live alongside (not inside) the Workspace surface.
