DEV3 AI Shopify Apps Bundle – 4 AI Apps Source Code (React Router 7 + Polaris)

The complete TypeScript source of four AI Shopify apps by DEV3 Technologies, in one npm workspaces monorepo with shared packages for Shopify API helpers, queues, billing and the Gemini client. Run them as your own apps in your own Partner Dashboard.

DEV3 AI Product Description & SEO Optimizer

Audits a whole catalog and writes titles, descriptions, meta tags and vision-based alt text in bulk. Nothing changes until the merchant approves, and every applied change can be rolled back for 30 days.

DEV3 AI Upsell & Cross-Sell Cart Drawer

A fast slide-out cart that suggests AI-ranked add-ons from the store's catalog and advertises bundle offers using the same rule engine (a Shopify Function) that checkout runs to apply them.

DEV3 AI Support Chat & Order Tracking Assistant

A storefront chat that shows order status only to the verified owner, answers from the store's own policies with cited sources, and hands complex cases to the merchant's helpdesk.

DEV3 AI Inventory & Supplier Price Sync

Syncs stock and prices from supplier feeds over SFTP, FTP, URLs or APIs, applies margin formulas and FX, and holds any suspicious run for approval after deterministic guards and an AI review.
