What are Gems in Gemini?

Recurring workplace tasks often require the same instructions, references, and output format. A custom Gem saves that setup and applies it each time you return to the task.

In this Quick Hit, you’ll build a Project Update Gem, define its boundaries, add a focused knowledge source, and test how it handles real notes, missing information, vague claims, and out-of-scope requests. You’ll also review the permissions that control who views or changes the Gem.

What you'll learn: 

  • Choose a recurring workplace task that fits a classic Gem
  • Write persistent instructions with clear boundaries and output rules
  • Add a focused knowledge source that supports the task
  • Test the Gem against normal, incomplete, vague, and out-of-scope requests
  • Review sharing roles and file visibility before wider use
This lesson assumes you already use Google Gemini and understand how to prompt effectively. You do not need coding experience, but you need access to the Gems feature in the Gemini web app.
