Chrome can now fill forms using your Gmail: how it works and how to turn it on or off
Google Chrome's new AI-powered enhanced autofill can read your Gmail to fill in flight bookings, order numbers and tracking details. Here's how it works, who gets it, the privacy questions, and how to control it.
Google Chrome’s autofill used to fill in simple things like your name, address and card number. Now it can do much more. Since October 28, 2026, Google has been rolling out an AI-powered “enhanced autofill” that can read your Gmail to fill in forms for you.
It’s handy, but it also raises privacy questions. Here’s how it works and how to control it.
What does it do?
When a website asks for something like an order number, a tracking number or a flight booking reference, Chrome can use Gemini, Google’s AI, to find it in your Gmail and suggest it in the form.
Example: you’re on an airline website checking in, and it asks for your booking code. Instead of searching your inbox, Chrome suggests the code from your confirmation email.
Who can use it?
- Where: rolling out in the United States first. Google hasn’t said when other countries will get it.
- Devices: Chrome on desktop, Android and iPhone/iPad.
- Requirements: you need Gemini in Chrome with Personal Intelligence turned on. This is Google’s opt-in feature that lets Gemini use connected apps such as Gmail.
It’s off by default. You have to choose to turn it on.
How to turn it on
- Update Chrome to the latest version.
- Make sure you’re signed in to Chrome with your Google account.
- Turn on Gemini in Chrome and allow Personal Intelligence to connect to Gmail when asked.
- Open Chrome Settings → Autofill and passwords and look for the enhanced autofill option to switch it on.
Note: Google is rolling this out gradually, so menu names and locations may vary slightly, and you may not see it yet.
How to turn it off
- Go to Chrome Settings → Autofill and passwords and switch off enhanced autofill.
- To fully stop Gemini reading Gmail, disconnect Gmail from Gemini’s connected apps (Personal Intelligence) in your Gemini settings.
- Optionally, review your activity at myactivity.google.com and delete anything you don’t want kept.
Google says you can manage whether enhanced autofill is enabled, and what it can access, in Chrome’s settings, and that you can disconnect apps at any time.
The convenience is real, but you’re giving an AI permission to search your inbox. Turn it on only if you’re comfortable with that trade-off.
Is it safe? The privacy questions
- Google says “sensitive data is encrypted and you remain in control.”
- What Google hasn’t fully explained: exactly how your Gmail content is processed when Chrome searches it, and how long related data is kept.
- Training: Google has said Gemini doesn’t train directly on Gmail content, but it does use some data such as prompts and responses.
Should you turn it on?
Turn it on if: you book flights or shop online often, you already use Gemini, and you’re comfortable with Google’s privacy approach.
Leave it off if: you use a shared or work computer, your email contains sensitive information, or you simply prefer to keep AI out of your inbox.
Frequently asked questions
Can Chrome read my Gmail?

Is it available outside the US?
Not yet. It’s rolling out in the US first, and Google hasn’t announced dates for other countries.
How do I stop Gemini from accessing Gmail?
Turn off enhanced autofill in Chrome settings and disconnect Gmail from Gemini’s connected apps.
