Gemini Gem: Definition and Creation (Google)
A Gemini Gem is a custom Gemini (Google) assistant, equivalent to OpenAI's Custom GPTs, configured with specific instructions and context for recurring use.
Full definition
Gemini Gems were introduced by Google in 2024-2025 as part of Gemini's ecosystem strategy, originally under Google Bard. A Gem is a preconfigured Gemini assistant that the user can create and then quickly invoke from the gemini.google.com interface or from Google Workspace apps.
A Gem is defined by:
- Behavioral instructions (role, tone, constraints) - A default context used: Drive documents, calendars, Gmail emails (depending on permissions granted) - Native integration with Google Workspace (Docs, Sheets, Slides, Calendar, Gmail) - An optional knowledge base via uploaded files
The major difference from a Custom GPT is the deep integration into Google Workspace: a Gem can natively analyze a shared Drive, read emails, write in a Doc — capabilities that in OpenAI require custom Actions to configure. On the other hand, the sharing and discovery ecosystem of Gems is less developed than the GPT Store.
Etymology
The name Gem (gem in French) evokes the notion of a precious and personalized object, and follows the lineage of Google AI product names (Gemini, before it Bard). Google explicitly positioned Gems as the cornerstone of their custom assistant strategy in 2024.
Concrete examples
Workspace productivity Gem
Create a Gem "Meeting Brief" that, from a Google Calendar event, reads the associated Drive attachments and generates a 1-page brief with context, objectives and questions to ask.
Personal assistant Gem orchestrating multiple Google apps
Configure a Gem "Inbox zero" that scans unread Gmail emails, classifies by urgency, suggests preformatted replies and creates Google Calendar tasks for important actions.
Business Gem leveraging a document corpus
Build a Gem "Financial Analyst" connected to a shared Drive containing quarterly reports from my portfolio, and answers questions by cross-referencing data.
Practical usage
To create a Gem, open gemini.google.com > Gems > Create a Gem. Define name, description, instructions, and choose default data sources (Drive, Gmail, Calendar). Gems are particularly powerful for productivity uses related to Google Workspace: email sorting, Calendar meeting summaries, leveraging a team Drive. They are invoked from the Gemini menu in any compatible Google app.
