Introduction
Google is blending conversational AI with e‑commerce, unveiling an “AI‑mode” chatbot that serves personalized product offers directly within user conversations. Powered by the same language model behind Google Search and Bard, the feature turns casual chat into an on‑the‑fly advertising channel, promising a smoother path from discovery to purchase.

## From Chat to Checkout: How AI‑Mode Works
– Intent Parsing: When a user mentions a product—e.g., running shoes, a home‑office desk, or a favorite coffee brand—the chatbot detects intent and product interest.
– Inline Offers: Instead of static banners, contextual prompts appear inline, linking directly to the item the user referenced or previously clicked.
– Shopping‑Assist Mode: Users can engage the chatbot in a dedicated shopping‑assist setting, where offers are surfaced only when relevant.
Key Benefit: A “more natural, less intrusive” ad experience that reduces friction between conversation and conversion, aiming for higher click‑through rates (CTR) and stronger return on ad spend (ROAS).
