# Build an AI assistant

A minimal **backend AI assistant** that accepts user questions over HTTP, maintains **sessions** per user, and optionally enables **dashboard logging**.

## What you will build

```
  Client (web/mobile)
         │ POST /api/chat { userId, message }
         ▼
  Your API server (DNotifier HTTP)
         │ sendAI + sessionId
         ▼
  DNotifier AI → JSON answer
```

{% hint style="info" %}
This example uses **`transport: "http"`** only. Realtime chat between humans uses WebSocket separately — see [Chat overview](/product-docs/chat/overview.md).
{% endhint %}
