About Gemini
Gemini is Google's AI assistant, available through the Gemini app and on the web. It is designed for conversational help, writing, summarizing information, brainstorming, and working with uploaded files. Depending on the user's Google account, region, plan, and app version, Gemini may also connect with Google services such as Gmail, Calendar, Drive, Photos, and Search.
Gemini is best understood as a general-purpose assistant rather than a guaranteed source of truth. It can produce useful drafts and explanations, but important facts, numbers, and citations should be checked before they are used.
