Inbox puts an AI-powered sales associate on your storefront. Buyers can ask questions and get help finding the right products from your catalog. When buyers sign in with Shop, your Inbox agent can personalize replies using their preferences and purchase history from across Shopify. Run Inbox with or without the agent. Inbox learns from your catalog, policies, and store content while you control its tone, style, and rules.

(HDYHAU) and compare revenue and AOV by channel with Meta Ads Manager and GA4. Collect zero-party data, NPS and CSAT, and learn why visitors don't buy. AI sorts open-ended customer feedback into themes and sends weekly reports. Sync answers to Klaviyo, Shopify Flow and Google Sheets, or query them with AI via API and MCP.
