Lesson 2 of 8
Gems
6 min read
You keep telling Gemini the same setup: "you're my chef, keep it short, use metric." Every single chat. What if you could bottle that once and just… reuse it?
A mini-assistant you build once
A Gem is a custom version of Gemini, pre-set for one job. You give it a name and a few standing instructions — a role, a tone, some rules — and save it. From then on, opening that Gem is like talking to a specialist who already knows how you like things, with no re-explaining.
A Gem packages your setup once, so every chat with it starts ready — in character, in format, on your terms.
Made for the jobs you repeat
Gems shine on anything you do again and again: a study coach, a code reviewer, a brand-voice writer, a meal planner. You can build your own in a few minutes with plain-language instructions, or start from one of the ready-made Gems. No coding — just describe how it should behave.
A Gem turns a good one-off prompt into a reusable tool you can open any time — or share with others.
Keep a Gem's instructions short and about how it should answer — its role, tone, and format. A tight brief steers far better than a wall of rules.
The shape of it
- —A Gem is Gemini pre-configured for one repeated job.
- —You set its instructions once; every chat with it follows them.
- —Build your own in minutes, or start from a ready-made one.
You review pull requests all week and keep pasting the same "be concise, flag security issues" instructions. What removes the repetition?
