Gemini
Japanese Gemini（ジェミニ）
Gemini is the name of Google's AI models and of the AI assistant app that runs on them. It is also built into Google services such as Gmail and Chrome, and how your input is handled depends on where you use it.
Gemini is one name for an AI that shows up in many places. There is a Gemini app you open on its own, and there is Gemini you call up with one button inside Gmail, Google Docs or the Chrome browser. It is like a staff member with the same name working at both the head office counter and a branch counter: the rules for handling your papers depend on which counter you used.
Watch out In the Gemini app on a personal account, human reviewers may read some chats, and Google asks you not to enter confidential information you would not want a reviewer to see. Activity is deleted after 18 months by default, and you can turn it off in settings. Google says Gemini in a work Google Workspace account is not used for training without permission, so first check which account you are using.
