Descriptions:
This tutorial from The AI Advantage walks through the full set of Google Gemini customization options that most users never configure — covering everything from activity and data retention settings to the Instructions feature, Gems, and Workspace connectors. The video addresses a common friction point upfront: what you can configure differs significantly between consumer Google accounts and Google Workspace accounts, with admin-level controls required for the latter via admin.google.com.
The core of the video demonstrates building a Gem — Gemini’s equivalent of a custom GPT — from scratch using an email writing assistant as the example. The host shows how to use Gemini’s built-in prompt enhancer to refine a basic instruction set into a structured system prompt defining goals, tone, and behavioral rules. Practical tips include integrating the Canvas writing tool into Gems for document-style output, and progressively encoding frequently-asked context (like a manager’s name) directly into the Gem to reduce repetitive input over time.
For the Instructions feature (persistent personal context spanning all chats), the video recommends structuring entries around identity, main goals, and the underlying “why” behind those goals — giving Gemini enough context to connect day-to-day requests to longer-term objectives. The host also notes that this feature has inconsistent availability, appearing on US accounts but not reliably on European ones even at the Ultra plan tier. Google Workspace connectors for Gmail and Google Calendar are tested and rated as unreliable in practice — a candid assessment that rounds out an otherwise enthusiastic guide.
