Disable Gemini in Gmail
Google's integration of Gemini in Gmail changes the way the email service is used. Features like 'Summarize' and writing suggestions, which Google calls an entry into the 'Gemini era,' are turning Gmail into a 'personal, proactive inbox assistant'. However, these innovations can be perceived as an intrusion into the usual routine, especially if the automatic functions are not transparent and a clear 'off' button is missing. Disabling Gemini in Gmail is usually not done directly via a Gemini switch, but through the settings for 'Smart features'.
Gemini in Gmail
Google is introducing new AI features in Gmail that are intended to make the service an assistant. These include summaries of long email threads, , the ability to query the inbox in natural language, as well as writing aids such as 'Help me write' and 'Suggested Replies'. The most visible innovation is the 'AI Overviews' directly in the thread, which summarize conversations concisely and update them with new replies. This feature is also being expanded as 'AI Overview in Gmail search' , allowing users to ask questions and receive synthesized answers from multiple emails, rather than just entering keywords.
The writing assistance includes 'Help me write,' which generates drafts or revises texts, and 'Suggested Replies,' which provides context-aware reply suggestions. Google promises less searching and scrolling as a result. However, this also means that Gmail analyzes content more extensively, which meets with resistance from users who prefer a simple email experience.

Smart Features
There is no direct 'Gemini: On/Off' switch in Gmail. Control is exercised through 'Smart features & controls,' which are divided into 'Smart features in Gmail, Chat & Meet,' 'Smart features in Google Workspace,' and 'Smart features in other Google products.' Google justifies this with 'more granular control', , even though the underlying privacy practices remain unchanged.
Turning off these features can disable classic convenience functions such as automatic inbox categories, Smart Compose, Smart Reply, or Summary Cards, in addition to AI summaries. For Google, these are all 'smart' functions that require context. For users, this often means a package deal: either Gmail thinks along or it leaves the user alone. Disabling Gemini in Gmail is therefore a decision about the entire smart feature ecosystem.

Disable intelligent features in Gmail to control Gemini.
In the browser, deactivation is done via the settings in the 'General' tab. To hide AI overviews, 'Smart features in Google Workspace' must be switched off, which also makes other Gemini functions such as the Gemini sidebar disappear. On the smartphone, the path is via Menu, Settings, select account, and then in the 'General' section under 'Smart features.' Here, there are also 'Google Workspace smart features' for separate control.
In Switzerland, 'Google Workspace smart features' are deactivated by default, which is why some users do not see the new AI overviews. To remove Gemini elements, two levels often need to be deactivated: the smart features in Gmail itself and the smart features in the Workspace context. This is the central logic of the new setting layer.

When switching off 'Smart features in Gmail, Chat & Meet,' automatic inbox categories, Smart Compose, Smart Reply, and Summary Cards also disappear. Smart Compose is an account setting that works across devices. Summary Cards extract information from emails about orders or travel. The new Gemini wave intensifies this effect, as AI Overviews, 'Help me write,' 'Suggested Replies,' and 'Proofread' are offered as a complete package. This leads to users who turn off AI often also losing other smart functions.
Privacy
For private Google accounts, Google refers to the Google Privacy Policy. . For Workspace accounts, the Google Cloud Privacy Notice. also applies. Google assures that content from Google Workspace will not be used to train Gemini or other generative AI models. Prompts and generated outputs will not be stored without permission.
Nevertheless, there are misunderstandings. Google has clarified that Gmail content is not used to train Gemini and that Smart Features have existed for years without this automatically meaning 'training.' There is a difference between 'a feature needs access to work for you' and 'content is used for model training.' Those who feel uncomfortable can reduce feature access and simplify the interface via the smart feature switches.
Business and School Accounts
In company and school accounts, deactivating Gemini is often a policy issue. Google offers an admin control 'Gemini for Workspace' to enable or disable Gemini features per service (including Gmail). Google points out that users can still ask questions about content from a deactivated service if Gemini is active in other services. To use Gemini in Workspace services, users must enable 'smart features and personalization' .

Administrators can disable Gemini for their organization in the Google Admin console.
This means that organizations that turn off Gemini centrally may find that a smart feature layer remains active or vice versa. A clear line regarding allowed functions and data flows, as well as internal communication, is necessary to resolve this cleanly.
