Google Chrome's Gemini-powered autofill now pulls form details from Gmail

• What it fills: Google lists order numbers, tracking information and flight bookings (Google). TechCrunch's list is longer: membership IDs, addresses, phone numbers and credit card numbers (TechCrunch).
• Requirements: U.S. location, Gemini in Chrome, and Personal Intelligence turned on. Users switch the feature on or off, and control what it can access, in Chrome settings.
• Model: Google does not name a model version for autofill. Personal Intelligence runs on the Gemini 3 family, according to DataCamp.
• Coming next: Google says autofill will soon pull from images in Google Photos, with no timeline (Thurrott).

Google has published no architecture, retrieval design or accuracy figures. What is documented:

• The feature works inside Chrome's normal autofill dropdown. A Gemini suggestion appears after Gemini has searched the inbox, and the email it came from is highlighted (Droid Life; Android Authority).
• The Chrome Canary test build drew on Gmail, Photos and "other connected apps." The stable release appears to use Gmail only (Android Authority).
• For form developers, this means more fields may be filled by an AI model rather than from a user's saved profile. Validating inputs on your side matters more as a result.
• There is no public benchmark or evaluation of how often it extracts the wrong value.

• "Sensitive data is encrypted" comes from Google only (Google). The reviewed sources do not say what encryption is used, where, or who holds the keys.
• User control in settings: Android Authority had not yet seen these controls in practice (Android Authority).
• No training on Gmail content: Google says it does not directly train models on Gmail or Photos content. It does train on filtered prompts and responses (afaqs!).
• Independent corroboration: none of the reviewed sources tests the feature's accuracy or its security.

• Earlier autofill expansions: Chrome's enhanced autofill grew in steps, first with Wallet IDs and vehicle details on desktop in November 2025, then on mobile in June 2026 (Android Central).
• Apple comparison: TechCrunch likens the feature to Apple's one-tap entry of verification codes from text messages (TechCrunch).
• Personal Intelligence reach: Google is extending Personal Intelligence across its products. The Search version is rolling out as a beta to adults worldwide, except in the EEA, Switzerland, the UK and Nigeria (The Hacker News).

• Ads question: The October 16 policy change lets connected Gmail data shape ads when users make it available to services that support personalised ads. Android Authority asks whether autofill data could be treated the same way; Google has not addressed this (Android Authority).
• Ad-off switch is not enough: Turning off personalised ads in My Ad Center does not necessarily stop connected-app data being used for AI personalisation (Relevant Audience).
• Reader poll: In a self-selected, non-representative Android Authority poll, 45% welcomed the feature, 32% rejected Gmail access outright and 23% wanted more granular controls.
• Conflicting data lists: Google and TechCrunch describe different sets of data types the feature can fill.

• Lock-in: The feature gives users a further reason to stay in Chrome and Google's AI ecosystem (TechCrunch). Browsers without access to the user's inbox cannot match it.
• Checkout and booking flows: Expect more fields to be pre-filled, such as order and confirmation numbers. Keep server-side validation in place.
• Enterprise: Admins should review whether Gemini in Chrome and Personal Intelligence are allowed on managed or work accounts, given the ad-policy change. The feature is U.S.-only for now.
