Google unveiled a major AI-powered overhaul of Search at I/O 2026, introducing an intelligent search box that expands for conversational queries and AI information agents that work 24/7 in the background. Powered by Gemini 3.5 Flash, the update moves Search beyond traditional blue links into interactive experiences. With over 2.5 billion monthly users already using AI Overviews, Google is doubling down on making AI the core of how people find information online.

Google Search Enters New Era with AI-Powered Overhaul

Google Search as users have known it for over two decades is fundamentally changing. At Google I/O 2026 on Tuesday, the company unveiled what it describes as the biggest transformation to its search box in more than 25 yearsโ€”an AI-powered overhaul centered around an intelligent search box and agentic features that shift how people interact with the web

The revamped experience marks a decisive move away from traditional search results. "This is really the next generation of what it means to be Search," said Robby Stein, Google's vice president of product for Search

3

. It accepts multimodal queries including text, images, videos, PDFs, and even open Chrome tabs as inputs

Driving this AI-heavy makeover is the new Gemini 3.5 Flash model, which Google describes as delivering "frontier performance for agents and coding, excelling at complex long-horizon tasks"

3

. The model enables faster inferencing, smarter results, and the ability to process different types of media, fundamentally changing how Search understands and responds to user intent

5

.

The conversational AI search experience now seamlessly transitions between AI Overviewsโ€”short summaries that appear at the top of resultsโ€”and AI Mode, Google's chatbot-like search interface

4

. Liz Reid, Google's vice president and head of Search, explained that the company wanted to eliminate the "friction" between these modes so users can simply go to the familiar search box and receive the best experience automatically

4

. Users asking natural-language questions will "reliably" see AI Overviews, and follow-up questions redirect them into AI Mode for deeper exploration

Agentic Features Transform Search Into Background Assistant

Google is entering what it calls "the era of Search agents," where users can create, customize, and manage multiple AI information agents within Search

3

. These agentic features represent an evolution of Google Alerts, the 2003 change-detection service that emailed users about new web results

1

. Unlike simple keyword tracking, these agents can work continuously in the background, monitoring topics 24/7 and making sense of changes across the web

Starting this summer, users will be able to deploy information agents for complex monitoring tasks. "You could send an alert to track market movements in a particular sector with very specific parameters, and the agent will map out a monitoring plan for you, including the tools and the data it needs to accessโ€”like our real-time finance data," Reid explained

1

. The agents then track changes and provide synthesized updates with links when conditions are met

1

. For apartment hunting, users can detail exact requirements, and agents will continuously scan listings, notifying them when matches appear

Generative UI Creates Interactive Experiences and Super Apps

Through a combination of Gemini and Google Antigravityโ€”the company's agentic development platformโ€”Search results now look more like interactive web pages

1

. The generative UI capability builds custom dynamic widgets and visualizations on the fly in response to user questions

1

. A question about black holes in space, for example, could generate an interactive visual that brings the concept to life, with the ability to ask follow-up questions and see brand new visuals in real-time

1

.

Google AI Pro and Ultra subscribers will gain access to create super apps directly within Search in the coming months

4

. Users can ask Search to build a home fitness tracker and connect it with real-time information like weather and calendar data

4

. These persistent mini apps become "stateful project spaces" that users can return to repeatedly and share with others

1

. The feature leverages multi-step workflows to create personalized tools tailored to individual needs

2

Booking Services and Personal Intelligence Expand Search Capabilities

Google is adding agentic booking capabilities for local services and appointments, allowing Search to show latest pricing and availability with direct links to complete reservations

3

. For select categories including home repair, beauty, and pet care, users can ask Google to call businesses on their behalfโ€”an evolution of the Duplex AI feature that launched with Google Assistant in 2018

3

5

.

The company is also expanding Personal Intelligence in AI Mode to nearly 200 countries and 98 languages without requiring a subscription

5

. This feature connects Gemini to Gmail, Photos, and Calendar information to deliver more accurate, personalized results

5

. Additionally, a new Universal Cart feature tracks shopping research across Search, Gemini, Google Pay, Gmail, and YouTube, remembering products under consideration and watching for price drops

Massive User Adoption Signals Shift in Search Behavior

The scale of adoption reveals how quickly AI has reshaped search behavior. AI Overviews now reach more than 2.5 billion monthly users, while AI Mode has surpassed 1 billion monthly users since launching last year

1

. For comparison, ChatGPT has 900 million weekly active users as of earlier this year, suggesting more frequent engagement with users returning repeatedly throughout the week, while Google captures more total unique people touching its AI features monthly

1

.

The updated search box with AI-powered autocomplete that goes beyond simple suggestions to help craft complex, nuanced queries rolls out globally across desktop and mobile starting Tuesday

1

4

. Users can still access traditional results by selecting the "Web" tab

4

. The new system, built free of charge for all Google users, fundamentally changes how "searching the web" worksโ€”increasingly performed by AI agents rather than humans manually clicking links

1

. "People can ask really anything on their mind and people's curiosity is fairly endless," Stein told reporters, framing the updates as doubling down on integrating frontier AI models with Google's live data to deliver deeper results
