Google (GOOGL) just announced the biggest Gmail update in 20 years. Gemini AI is now embedded across the platform, bringing AI-generated thread summaries, natural language search, smart replies, and a completely redesigned inbox view. FYI: these features are turned on by default for all 3 billion Gmail users. If you don’t want AI reading your email, you have to opt out.

The new features are genuinely useful. Ask your inbox, “Who was the plumber that gave me a quote last year?” and Gemini pulls the answer instantly. Open an email thread with 47 replies and get a concise summary of key points. Help Me Write, previously a paid feature, is now free for everyone.

In the U.S., Gemini access to Gmail is enabled automatically. You have to manually find the settings and turn it off. In Europe, GDPR requires explicit opt-in consent, so Gemini is off by default and users must actively enable it. Same product, opposite defaults, based entirely on regulation.

The opt-out process is a little bit complicated. If you want to turn it off, here’s how:

Step-by-Step (Web/Desktop):

1. Open Gmail in your browser.
2. Click the gear icon in the top right and select See all settings.
3. Scroll to Smart features and personalization under the General tab.
4. Uncheck “Turn on smart features in Gmail, Chat, and Meet.”
5. Scroll down to Google Workspace smart features and click Manage Workspace smart feature settings.
6. In that screen, turn off both “Smart features in Google Workspace” and “Smart features in other Google products.”
7. Save changes if prompted.

On Mobile (Gmail App):

1. Open the Gmail app.
2. Tap Menu (three lines) at top left” or “settings at the bottom of the inbox menu” → Settings → choose your account.
3. Scroll to Data privacy at the bottom.
4. Turn off Smart features.
5. Then open Google Workspace smart features and turn those off, too.

Turning these settings off disables AI-driven suggestions, summaries and other automated actions tied to Gemini or smart features, but be careful: it also affects many of Gmail’s built-in conveniences such as automatic categorization, predictive text, and quick suggestions.

At the moment, Google does not offer a single “Gemini off” switch separate from these smart features.
