From Gemini Native Checkout to UCP: Everything Google Announced on AI Shopping

Google has announced a significant expansion of its AI-shopping ecosystem, introducing new commerce features built atop its Gemini AI and AI Mode in Search that allow users to discover, interact with, and purchase products without ever leaving the AI interface. These innovations signal the company’s strategy to turn conversational AI into a central hub for ecommerce experiences.

Native Checkout in Gemini and Search

One of the biggest highlights is the rollout of an AI-driven checkout feature that enables users to buy products directly while searching or chatting with Gemini, using payment methods like Google Pay. This means you can browse, compare, and purchase all within the same experience, removing the need to jump to retailer websites.

• Currently, eligible US-based retailers are participating in the pilot.

• Google Pay integration lets users complete purchases seamlessly and securely.

This step integrates commerce more deeply into AI interactions and helps shorten the path from product discovery to purchase.

Universal Commerce Protocol (UCP)

At the core of Google’s AI shopping strategy is the Universal Commerce Protocol (UCP) — an open standard developed with major ecommerce and payments partners to support agentic AI commerce end-to-end.

What UCP enables:

• A common language for different AI agents and ecommerce systems to interact.

• Support for entire shopping flows: product discovery, checkout, and post-purchase tasks.

• Compatibility with existing protocols like Agent2Agent (A2A), Agent Payments Protocol (AP2), and Model Context Protocol (MCP).

By standardising how AI systems communicate with retailer inventories and payment processors, UCP lays the groundwork for seamless AI-assisted shopping across platforms.

Business Agent

Google introduced Business Agent, a feature that lets brands deploy their own AI shop assistants directly within Google Search.

• Acts like a virtual sales associate answering product questions in the brand’s tone.

• Retailers can personalise these agents via Merchant Center to reflect their identity and offerings.

This brings brands closer to customers at crucial decision points — earlier than ever before.

Direct Offers

Another new tool, Direct Offers, allows retailers to serve exclusive promotions — like special discounts — directly in AI Mode.

• Retailers set up offers in their campaign settings.
• Google’s AI decides when and where to show them based on relevance to the user’s journey.

This could change how consumers encounter promotions, making offers more personalised and context-aware.

Merchant Center Updates

Google is also enhancing Merchant Center with new product attributes:

• Answers to common product questions
• Compatible accessories or substitute recommendations

These additions help retailers present richer product information that AI agents can use to provide better shopping answers.

Gemini Enterprise for Customer Experience (CX)

To support retailers beyond just purchase flow, Google has unveiled Gemini Enterprise for CX — a suite of pre-built AI agents that manage the entire customer lifecycle, including discovery, order support, and even autonomous post-purchase resolution.

For example:

• Restaurants can integrate natural language ordering across devices.
• Agents can handle upselling and menu sync in real time.

What This Means

Google’s moves place the company deeper into the AI commerce race, competing directly with others like OpenAI and Amazon, which are also pushing AI-enabled shopping breakthroughs.

By merging search, AI chat, shopping, and payments, Google aims to redefine traditional ecommerce workflows — from browsing to checkout — inside a unified AI experience.
