Google announces 'Universal Cart,' which uses AI to automatically monitor prices and optimize checkout

Google unveiled Universal Cart and UCP at I/O 2026 to unify shopping across Search, Gemini, and other services.

Gemini will track price changes, send restock alerts, check item consistency, and suggest the best payment method.

The rollout starts in the U.S. this summer through Search and Gemini, then expands to other Google products.

The move could reshape e-commerce by linking discovery, comparison, checkout, and delivery tracking with AI.
