Google started testing ads in AI Mode for users who connect Gmail, Calendar, and Photos through Personal Intelligence. Now, what the AI knows about a user in order to answer their questions can also help decide which ads to show them.
On October 16, 2026, Google confirmed to Search Engine Land that it’s testing ads in AI Mode for users who connect their apps. On October 19, Search Engine Roundtable published the updated help page: ads won’t be based “directly” on a user’s Gmail inbox or Photos library, but Search can use “summaries, snippets, and inferences” from those sources, and that same information can be used to show ads “to make them even more useful.” According to Techlicious, the privacy policy was updated that same day, October 16.
On March 17, a spokesperson told Search Engine Land that “there are currently no ads” for users who connect their apps and that “this isn’t changing for now.” In the same statement, the spokesperson suggested that ads would eventually work similarly for those users. Google’s official announcement that day made no mention of the possibility of ads.
The shift in language, from “there are no ads” to “more useful” ads, marks the moment when an AI assistant’s personal context becomes an advertising asset. For brands, that means targeting is no longer defined solely by what someone searches for, but by what the AI infers about their life.
What changes in practice
Until now, a Google ad responded mainly to what a user searched for. With this test, it can also respond to what Google infers from their emails, calendar, and photos. The example Google gives, according to Techlicious, is AI Mode reading a hotel booking, a flight itinerary, and restaurants from past trips to recommend places near the hotel.
Google maintains some limits. The connection is optional and can be turned off. Advertisers don’t get access to connected apps. Sensitive categories like religion, health, or sexual orientation aren’t used. Techlicious adds two caveats: disconnecting an app doesn’t delete the information Search has already stored, and turning off personalized ads in My Ad Center doesn’t stop that data from being used to personalize the AI.
What remains unknown
Google hasn’t disclosed the size of the test, which countries it’s running in, what ad formats are involved, or whether new controls will be introduced for advertisers. Search Engine Land notes that Google hasn’t announced targeting options or a broader rollout. Personal Intelligence was available in the United States as of March, but there’s no confirmation that the test is limited to that country.
What it means for brands
If user context drives targeting, advertisers lose part of their control over why their ad appears. They don’t choose an audience: Google decides, based on inferences the advertiser can’t see, when their product is relevant. That favors brands that already have strong signals in that context, like purchase confirmations in Gmail or photos of their products, and makes it harder for those that don’t to break in.
The boring explanation
Google lives off advertising, AI Mode is taking clicks away from traditional results, and it needed to monetize it. Testing ads in the personalized version was only a matter of time, and Google had already signaled as much.
What’s new isn’t that there are ads in AI Mode, which were already being tested, but that the raw material for targeting now becomes what the AI knows about the user. What could change this reading is if Google limits the test to signals from the query itself rather than connected apps, something its own help page currently doesn’t say.
What to watch next
The first thing to watch is whether Google expands the test, and to which countries, especially outside the United States, where privacy rules are stricter. The second is whether controls tied to Personal Intelligence appear for advertisers. The third is how many users disconnect their apps once the ads become visible.
If the assistant that plans your trip also decides which hotel to show you as an ad, the line between recommendation and advertising will depend on a label the user may never read.
