Gems

Gems are custom Gemini personalities you build inside the Gemini chat app — instructions, optional knowledge files, and a name. Think of them as the Gemini-app equivalent of Custom GPTs: no-code chat assistants tailored for a specific role (Coding Partner, Writing Editor, Career Guide, etc.) Google ships several premade Gems for free; custom Gems live behind a paid Google AI Pro / Ultra subscription. Different from the Apps SDK / Vertex AI Agents — Gems are no-code, chat-only, and live inside the Gemini app. Sourced from gemini.google.com/app/gems.
