ChatIn hasshut down
The AI sales and support agent for Shopify stores was discontinued on . The app is uninstalled from every store and all merchant and customer data has been deleted.
What it was
ChatIn put an AI agent on the Shopify storefront. Shoppers asked it for products, compared options, added items to their cart and went to checkout without leaving the chat. The same agent answered order, shipping and returns questions and handed the conversation to a human when it had to. It shipped an agentic shopping experience in mid-2025, before the major storefront-chat vendors offered one.

How it worked
A solo build, end to end: storefront widget, multi-agent backend, merchant app, sync pipelines and billing.
Storefront widget
A React custom element in a shadow DOM, injected by a Shopify theme app extension. It talks to the backend over a WebSocket through the Shopify app proxy, streams the reply token by token, and renders structured data items (product cards, collection cards, variant chips, cart and checkout actions, tracking cards) as they arrive.
Multi-agent backend
Node.js and LangGraph. A supervisor classifies each message with structured output and routes to a sales agent or a support agent, each with its own system prompt and tool set. The graph is flattened so every node is checkpointed and a conversation can be replayed step by step.
Tool layer
Hybrid semantic search over the synced catalog (vector plus full-text with reciprocal rank fusion), collection browsing, product details and comparison, knowledge-base search, add-to-cart, checkout, order tracking and human escalation. Each tool returns a typed result that becomes a per-tool instruction telling the model which data models to emit.
Guardrails
A JSON-only response contract validated on the server; escalation gated behind a tool that requires real contact details; separate tool sets for anonymous and logged-in customers; off-topic routing; prompts and tool descriptions versioned in the database and editable from an admin console without a deploy.
Data and sync
Azure Cosmos DB for products with embeddings, collections, customers, orders, knowledge chunks, conversations, checkpoints and per-shop memory. Azure Functions on Service Bus queues handle catalog sync, Shopify webhooks, analytics and nightly memory generation from conversation checkpoints.
Merchant app and platform
An embedded Remix app for onboarding, inbox, analytics, training data and billing. Shopify OAuth, usage-based billing, GDPR compliance webhooks, and Slack, Discord, email, WhatsApp and Messenger integrations for escalations and notifications.
Evaluation
No offline benchmark; the product was small enough to evaluate on live traffic. Every graph step was checkpointed, a nightly job classified each conversation by topic and outcome, and shoppers could rate the interaction in the widget. Those three sources are where the numbers above come from.
Why it ended
The product worked; the business did not. Almost every install stayed on the free tier, free-tier stores churned quickly, and the one paying account generated more support load than revenue. Per-conversation model cost never fell below what merchants were willing to pay. With unit economics negative for over a year, sunsetting was a decision, not an accident: merchants were notified, subscriptions cancelled, the app uninstalled from every store, and all data deleted on the shutdown date.
