Google Chrome with Gemini Auto Browse: The Browser Becomes an AI Agent

Google just transformed Chrome from a passive browser into an active AI agent. The new Gemini 3 integration includes Auto Browse, a feature that can execute complex multi-step tasks on behalf of the user.

What is Auto Browse?

Auto Browse is an agentic capability that allows Chrome to perform tasks automatically:

Capability	Example
Navigate between tabs	Search multiple sites simultaneously
Compare products	Analyze prices and features across stores
Apply coupons	Find and apply discount codes automatically
Complete forms	Fill repetitive information
Research topics	Gather information from multiple sources

New Gemini Features in Chrome

1. Persistent Side Panel

Gemini now has a permanent side panel instead of a floating window:

• Always visible while browsing
• Current tab context available
• Persistent conversation history
• Multitask without switching windows

2. Context Groups

Allows analyzing multiple tabs simultaneously:

Usage example:

"Compare these 3 hotels I have open:
 - Price per night
 - Distance to downtown
 - User ratings
 - Cancellation policies"

Gemini analyzes all 3 tabs and generates a comparison table.

3. Universal Commerce Protocol (UCP)

Google introduced a new open standard for agentic commerce, developed with:

Partner	Role
Shopify	E-commerce
Etsy	Marketplace
Wayfair	Retail
Target	Retail

This allows Auto Browse to interact securely with online stores.

Security and User Control

Google implemented multiple security layers:

Explicit confirmation required for:

• Making purchases or payments
• Posting on social media
• Sending emails or messages
• Modifying account settings

Built-in protections:

• Malicious site detection
• Form authenticity verification
• Sandbox for sensitive actions
• Logs of all agent actions
