📝 Abhijeet's Take: I just bought a laptop charger without leaving Gemini. Asked "best laptop charger under ₹2000", got recommendations, compared prices, and checked out - all in chat. This is the future. Amazon should be worried.
What is Universal Commerce Protocol?
Universal Commerce Protocol (UCP) is an open standard that enables AI agents to handle the entire shopping journey - from product discovery to checkout - directly within chat interfaces.
UCP in Simple Terms:
- Before: Search → Click link → Open website → Add to cart → Checkout (5+ steps)
- After: Ask AI → Buy (1 step)
How It Works
The Shopping Flow:
- Discovery: Ask Gemini for product recommendations
- Research: AI shows options with prices, reviews, specs
- Compare: Side-by-side comparison in chat
- Checkout: Buy directly using Google Pay
- Track: Order tracking in chat
- Support: Post-purchase help via AI
💭 Real Example: I asked Gemini "wireless earbuds under ₹5000 with good bass". Got 5 options from different retailers, compared features, read reviews, and bought - all without opening a single website. Took 2 minutes.
Key Features
1. Instant Checkout in Chat
No more navigating to external websites. Complete purchases directly in Gemini using saved payment details.
Supported Payment Methods:
- ✅ Google Pay (available now)
- ✅ PayPal (coming soon)
- ✅ Saved credit/debit cards
- ✅ UPI (India)
2. Business Agent
Chat directly with brands in Google Search. It's like having a virtual sales associate for every store.
Example Conversation:
You: "Does this Nike shoe fit wide feet?"
Nike Business Agent: "Yes! The Air Max 270 has a wider toe box. Based on your previous purchases, I recommend going with your usual size 10. Would you like to see similar wide-fit options?"
Early adopters: Lowe's, Michaels, Poshmark, Reebok
3. Direct Offers
Google's AI detects when you're close to buying and surfaces exclusive discounts.
How It Works:
You're researching "iPhone 15 Pro Max"
Gemini: "I noticed you've been looking at iPhone 15 Pro Max. Flipkart has an exclusive offer: ₹8,000 off + free AirPods with purchase today. Interested?"
