Google has introduced a new AI feature called Dive Deeper as part of its Discover service, which curates news and content for users. The feature was announced by Robby Stein, Google's Vice President of Product, in a post on X. Dive Deeper has been available since September 18, 2026, and appears as a button beneath the AI-generated summary of a video card in the Discover feed. When users click the button, they are taken to a more detailed AI-generated overview of the topic, including links to related articles, community reactions, and original reports. A second screen titled Explore more stories then breaks the topic down into several angles, each with links to other media. The feature is currently in a test phase. Stein mentioned that Google will test "several designs in the coming weeks" to refine the user experience. For now, the Dive Deeper feature applies only to video content, though Damien Andell, co-founder of the analysis service 1492.vision, has noted that configuration markers affecting article cards have also been identified. The countries involved and the percentage of users exposed to the test have not been specified. Accessing content from social networks requires users to accept cookies and advertising trackers, which allow partners to offer personalized ads and content based on browsing habits, profile data, and interests. The Dive Deeper feature builds on AI summaries that have been tested in Discover since October 13, 2025, in the United States, South Korea, and India. Previously, these summaries directed users directly to the source. Now, an intermediate screen is introduced, with links to publishers that only appear at the bottom of this preview, also generated by Google. The gradual rollout of these AI previews risks further destabilizing publishers, who are already struggling with declining traffic linked to AI Overviews on traditional search. Last July, Bérangère Farcot, marketing and audience director of the Swiss media outlet Le Temps, told BDM that for evergreen and service-related content most affected by AI previews, the click-through rate has dropped by half since their introduction, from 6.8% to 3.3%. "For us, Google remains the main traffic provider, but mainly through the Discover channel. What is interesting is to see what happens when Overviews are deployed on Discover," she said at the time. To generate these previews, Google relies on content produced by publishers, which could reignite debates over their compensation. Recently, the company has been testing a compensation program called AI Contribution, which plans to pay publishers when their content is used to generate AI responses. The program, not yet publicly announced, is based on a notion of "value" that several participating editors find unclear.
