Chat SDK now supports Velt with the new [vendor-official adapter](https://chat-sdk.dev/adapters/vendor-official/agentphone).

Build bots that read and reply within Velt comment threads, right where your team already works: documents, text editors, and canvases. Tag the bot, and it will answer in the same thread, grounding its reply with the document name, URL, and anchored text.

**lib/bot.ts**
```typescript
import { Chat } from "chat";
import { createVeltAdapter } from "@veltdev/chat-sdk-adapter";
const bot = new Chat({
  userName: "mybot",
  adapters: {
    velt: createVeltAdapter(),
  },
});
bot.onNewMention(async (thread, message) => {
  await thread.post(`You said: ${message.text}`);
});
```

The adapter maps Velt documents to Chat SDK channels, comment annotations to threads, and individual comments to messages.

Read the [Velt](https://velt.dev/docs/ai/chat-sdk-adapter) documentation to get started.
