Google unveiled a radical overhaul of Search at I/O 2026, replacing the traditional search box with an AI-powered interface built on Gemini 3.5 Flash. The update introduces “information agents” that monitor the web around the clock, generative UI that builds custom tools on the fly, and mini-apps users can create in natural language.TL;DR
For a quarter of a century, Google Search has opened with the same proposition: a blank white rectangle, a blinking cursor, and the implicit instruction to reduce your question to a handful of keywords. On Monday, at its annual I/O developer conference, Google declared that era over.
The company unveiled what it calls an “intelligent search box,” a dynamically expanding input field powered by Gemini 3.5 Flash that accepts text, images, files, video, and even open Chrome tabs. Rather than returning a list of blue links, the redesigned interface drops users into AI-generated interactive experiences, complete with custom visualisations, tools, and what Google is calling “information agents” that monitor the web around the clock on your behalf.
Liz Reid, Google’s vice president and head of Search, described the update as “the biggest upgrade to our iconic search box since its debut over 25 years ago.” The language is deliberate. Google is not tweaking autocomplete; it is reimagining the foundational interaction between its flagship product and the billions of people who use it every month.

The numbers framing the announcement are staggering. AI Overviews, the feature that places AI-generated summaries above traditional results, now reaches 2.5 billion monthly users. AI Mode, the conversational search interface launched just a year ago, has crossed one billion monthly users, with queries more than doubling every quarter. For context, OpenAI reported that ChatGPT hit 900 million weekly active users in February 2026.
Google’s response to that competitive pressure is not to retreat into its legacy format but to push further into agentic territory. Information agents, the headline feature of the announcement, work in the background 24/7, reasoning across blogs, news sites, social posts, and real-time data on finance, shopping, and sports to alert users when something relevant changes. Think of Google Alerts, the 2003-vintage notification tool, rebuilt with a frontier language model’s capacity for nuance and inference.
Information agents will launch this summer for Google AI Pro and Ultra subscribers in the United States. The new search box, meanwhile, begins rolling out globally this week.
Beyond the search box itself, Google introduced “generative UI,” a system in which Gemini 3.5 Flash builds custom widgets, simulations, and visual tools on the fly to match a query. Ask about mortgage rates and you might see a live calculator; ask about a hiking trail and you could receive an interactive map with elevation data.
Even more ambitious is Antigravity, Google’s platform for building agentic experiences, which is being woven directly into Search. Users will be able to describe a “mini-app” in natural language, a custom fitness tracker or a wedding planner, for instance, and Search will code it on the spot, pulling in real-time data from reviews, maps, and local sources. Mini-apps will also arrive this summer for AI Pro and Ultra subscribers.
Generative UI, by contrast, will be free for everyone, a distinction that signals Google’s intent to keep its broadest user base engaged while reserving the most capable agentic features for paying customers.
The shift carries significant implications for publishers and the broader web ecosystem. If Google’s AI can synthesise information, build interactive tools, and dispatch background agents to track changes, the incentive for users to click through to source websites diminishes further. Referral traffic from Google Search has already been declining as AI Overviews expanded, and the new features are likely to accelerate that trend.
The European Union is already paying attention. In April, the European Commission published measures requiring Google to share anonymised search data with rival search engines and AI chatbot providers under the Digital Markets Act, with a compliance deadline of 27 July 2026. The more Google’s search interface resembles a self-contained AI application, the sharper the regulatory scrutiny is likely to become.
None of this is happening in isolation. The broader industry is moving rapidly toward AI-driven search paradigms, with OpenAI, Perplexity, and others building conversational alternatives. Google’s advantage remains its scale, 2.5 billion monthly users is a moat few competitors can approach, but the company is clearly betting that the best defence is to make its own product unrecognisable from the one that defined the internet age.
The search box is dead. Long live the search agent.
