Google has started testing a feature inside Discover called “Dive deeper” that opens an AI-generated topic overview instead of sending the tap to a publisher’s page. Google’s Robby Stein announced the test late on a Friday on X. The rollout starts with video content and multiple visual designs are being tried over the coming weeks.
The mechanic works in two layers. Tapping “Dive deeper” on a Discover card surfaces a short, AI-generated topic overview, labeled “generated with AI” and carrying Google’s standard disclaimer that the summary “can make mistakes.” A longer version of the overview does include links to publisher articles, alongside community reactions and what Google calls original reporting.
Stein described the goal as making “exploring a topic and discovering related web content easier in Discover.” His fuller explanation: by tapping “Dive deeper,” a user sees “a short topic overview with prominent links to related stories, community reactions and original reporting.”
The design puts a fully formed AI answer ahead of any single publisher’s version of the story, then asks the reader to choose to go further. That ordering matters more in Discover than it would in a standard AI Overview, because Discover traffic already skews toward users browsing passively rather than searching with intent. A summary that resolves the “what happened” question up front could remove the main reason a passive browser taps through at all.
Barry Schwartz, who broke the test for Search Engine Roundtable, raised that concern directly: the AI-generated overview gives a user “the full context,” so he questioned why that user would still click to a publisher’s site. Google’s announcement, notably, includes no data on click-through rates or how the first-layer summary affects traffic to the linked sources.
This test also follows a separate, more drastic change to the same product. On September 18, we reported that Discover had disappeared from the desktop version of Google.com, with no public explanation for the removal. Read together, the two changes point toward Discover shrinking as a direct-to-publisher channel: gone from one surface, and on the surface where it remains, now interposing an AI summary between the reader and the source.
Neither change has a confirmed cause tied to the other, and Google has not said whether “Dive deeper” will expand beyond video content or reach desktop Discover if that surface returns. What is measurable now is exposure. Publishers who rely on Discover for a meaningful share of referral traffic should isolate that segment in Search Console and Google Analytics this quarter, so any drop tied to the AI overview layer is visible before it gets buried in normal seasonal swings.
