+title: Quick Replies
+description: Quick start guide for quick replies in FastGPT chat
+---
+
+Quick replies let the AI output a group of clickable buttons in its response. When a user clicks a button, FastGPT sends that button text directly as the user's next message. This is useful for customer support, product introduction, sales guidance, and other scenarios where users need clear next-step options.
+
+## Usage
+
+Output a `quick-replies` code block in the AI response. Each line inside the code block is rendered as one quick-reply button.
+
+### Syntax
+
+````md
+```quick-replies
+View feature introduction
+Learn pricing plans
+Book a product demo
+```
+````
+
+### Preview
+
+![](/imgs/chat/specialMarkdown/quickReplies.png)
+
+## Notes
+
+- Write one quick-reply option per line. Blank lines are ignored.
+- The total code block content must not exceed 300 characters.
+- Clicking a quick reply sends the corresponding text directly and does not clear existing input.
+- If the AI is still responding, clicking a quick reply will not send a new message immediately. FastGPT will prompt the user to wait until the current chat finishes.
+- Quick replies only take effect in chat contexts where this capability is enabled, such as app chat, share link chat, and home chat.
+
+## Recommended Format
+
+We recommend providing 2 to 5 short and clear options each time.
+
+````md
+```quick-replies
+Check order status
+Request after-sales service
+Contact support
+```
+````

+title: 快捷回复
+description: FastGPT 对话中快捷回复的快速使用说明
+---
+
+快捷回复可以让 AI 在回复中输出一组可点击的按钮，用户点击后会直接发送对应文本。它适合用于客服咨询、产品介绍、售前引导等需要给用户提供下一步操作选项的场景。
+
+## 使用方式
+
+在 AI 回复正文中输出 `quick-replies` 代码块，代码块内每一行都会渲染为一个快捷回复按钮。
+
+### 语法
+
+````md
+```quick-replies
+查看功能介绍
+了解价格方案
+预约产品演示
+```
+````
+
+### 效果图
+
+![](/imgs/chat/specialMarkdown/quickReplies.png)
+
+## 使用说明
+
+- 每行一个快捷回复选项，空行会被自动忽略。
+- 代码块内容总长度不超过 300 字符。
+- 点击快捷回复后，会直接发送对应文本，不会清空输入框中已有的内容。
+- 如果当前 AI 仍在回复中，点击快捷回复不会立即发送新消息，而是提示「正在聊天中……请等待结束」。
+- 快捷回复仅在已开启该能力的对话场景中生效，例如应用对话、分享链接对话、首页对话等。
+
+## 推荐写法
+
+建议每次提供 2 到 5 个选项，并让选项尽量简短明确。
+
+````md
+```quick-replies
+查询订单进度
+申请售后服务
+联系人工客服
+```
+````
