A Gemini Gem is like creating your own AI assistant for one specific job. In this video, I walk you through exactly how to build your first Gem inside Google Gemini so you can stop rewriting the same prompts over and over again. I show you where to find Gems in the left-hand menu (and which “Gem Manager” area to use), how to name your Gem in a descriptive way, and why adding a short description helps you stay organized once you start building more of these. The real magic is in the instructions. I demonstrate how I set up a Gem that takes uploaded discovery call meeting notes and produces a complete client proposal with three options. You’ll see how to save early (because I like to be saved), how to test your Gem in the preview/chat window, and how to use Gemini’s “rewrite” button to expand simple instructions into a more detailed set of rules, structure, and even a comparison table. I also cover default tools and the knowledge base—when to leave defaults alone, and when it makes sense to add reference material—so you can repurpose the same Gem again and again without feeling overwhelmed.
