Google search is becoming something fundamentally different

At a glance:

• Gemini 3.5 Flash becomes the default engine behind AI Mode worldwide
• An "intelligent search box" that expands for long queries, accepts uploads and pulls context from open Chrome tabs
• AI‑driven widgets and agentic features will roll out this summer across 200 markets and 98 languages

Google unveils a new AI‑first search experience at I/O 2026

Google used its annual I/O developer conference in Mountain View, California, to signal a decisive shift away from the classic blue‑link search layout that has dominated for more than 25 years. Vice‑president of Search product Robby Stein framed the announcements as the next evolution of the company’s “AI Overviews” and “AI Mode” into a unified, conversational search experience. He noted that a billion people now use Google’s AI Mode each month and that the new system will answer more complex, multi‑step queries by tapping into live web data, business listings, product catalogs, images and financial information.

Gemini 3.5 Flash powers the new default AI engine

The centerpiece of the upgrade is Gemini 3.5 Flash, a frontier model that Google says is more capable at reasoning, coding and handling intricate tasks. Stein explained that building Search tools around this model “raises the overall answer quality on Search.” Gemini 3.5 Flash will be the default engine behind AI Mode globally, meaning every user who enables the mode will be interacting with the latest model without needing to opt‑in separately.

Intelligent search box expands the way we query

Alongside the model upgrade, Google is introducing an intelligent search box that dynamically expands for longer, more nuanced questions. Key capabilities include:

• Accepting uploads such as photos and PDFs
• Auto‑completing sophisticated prompts
• Accessing contextual sources like open Chrome tabs to support multi‑step research
• Seamlessly transitioning AI Overviews into AI Mode for follow‑up conversations These changes let users ask “real‑world” questions—like planning a move or tracking health metrics—without leaving the search page.

New widgets turn search results into mini‑apps

Google also showcased dynamic widgets and larger super widgets generated by Gemini and developer tooling. The widgets can:

• Simulate physics or visualize concepts
• Build calculators on the fly
• Act as persistent mini‑apps for tasks such as moving, health tracking or trip planning When users grant permission, the widgets can pull personal data from Gmail, Photos or Calendar to personalize results. The system will be available in 200 markets and 98 languages.

Agentic era: AI agents assist with everyday tasks

Stein described the upcoming features as ushering Search into an “agentic” era. AI agents will be able to monitor topics, send alerts (e.g., when a favorite artist announces a tour) and help with reservations. While the agent cannot complete a booking directly, users can share details like preferred dates, party size and budget to receive curated lists with up‑to‑date availability and pricing, plus links to finalize the reservation. Google plans to make these capabilities generally available this summer.

What this means for users and developers

For everyday users, the overhaul promises a more conversational, task‑oriented search experience that feels closer to interacting with a personal assistant than a list of links. Developers will gain new APIs to create custom widgets and integrate personal data sources, expanding the ecosystem of third‑party services that can run inside Google Search. The rollout across nearly every market and language suggests Google is betting on AI to keep its search dominance amid rising competition from generative‑AI‑centric platforms.

Looking ahead

Google’s pivot raises questions about privacy, data usage and the balance between helpful personalization and intrusive profiling. As the intelligent search box and agentic features gather more contextual data, regulators and privacy advocates will likely scrutinize how consent is obtained and how long user data is retained. Observers will also watch how quickly competitors can match Google’s integrated AI stack, especially as other big tech firms accelerate their own generative‑AI search experiments.
