 ## 主要功能
 
 - 本地实时查看聊天记录
+- 朋友圈图片、视频、**实况**的预览和解密
 - 统计分析与群聊画像
 - 年度报告与可视化概览
 - 导出聊天记录为 HTML 等格式
-- 本地解密与数据库管理
+- HTTP API 接口（供开发者集成）
+- 查看完整能力清单：[详细功能](#详细功能清单)
 
 ## 快速开始
 
 若你只想使用成品版本，可前往 Release 下载并安装。
 
+## 详细功能清单
+
+当前版本已支持以下能力：
+
+| 功能模块 | 说明 |
+|---------|------|
+| **聊天** | 解密聊天中的图片、视频、实况（仅支持谷歌协议拍摄的实况）；支持**修改**、删除**本地**消息；实时刷新最新消息，无需生成解密中间数据库 |
+| **实时弹窗通知** | 新消息到达时提供桌面弹窗提醒，便于及时查看重要会话，提供黑白名单功能 |
+| **私聊分析** | 统计好友间消息数量；分析消息类型与发送比例；查看消息时段分布等 |
+| **群聊分析** | 查看群成员详细信息；分析群内发言排行、活跃时段和媒体内容 |
+| **年度报告** | 生成按年统计的年度报告，或跨年度的长期历史报告 |
+| **双人报告** | 选择指定好友，基于双方聊天记录生成专属分析报告 |
+| **消息导出** | 将微信聊天记录导出为多种格式：JSON、HTML、TXT、Excel、CSV、PGSQL、ChatLab专属格式等 |
+| **朋友圈** | 解密朋友圈图片、视频、实况；导出朋友圈内容；拦截朋友圈的删除与隐藏操作；突破时间访问限制 |
+| **联系人** | 导出微信好友、群聊、公众号信息；尝试找回曾经的好友（功能尚不完善） |
+| **HTTP API 映射** | 将本地消息能力映射为 HTTP API，便于对接外部系统、自动化脚本与二次开发 |
+
+## HTTP API
+
+> [!WARNING]
+> 此功能目前处于早期阶段，接口可能会有变动，请等待后续更新完善。
+
+WeFlow 提供本地 HTTP API 服务，支持通过接口查询消息数据，可用于与其他工具集成或二次开发。
+
+- **启用方式**：设置 → API 服务 → 启动服务
+- **默认端口**：5031
+- **访问地址**：`http://127.0.0.1:5031`
+- **支持格式**：原始 JSON 或 [ChatLab](https://chatlab.fun/) 标准格式
+

+### JavaScript / Node.js
+
+```javascript
+const BASE_URL = "http://127.0.0.1:5031";
+
+// 获取会话列表
+const sessions = await fetch(`${BASE_URL}/api/v1/sessions`).then(r => r.json());

+  .then(r => r.json());
+console.log(messages);
+```
+
+---
+
+## 注意事项
+
+1. API 仅监听本地地址 `127.0.0.1`，不对外网开放
+2. 需要先连接数据库才能查询数据
+3. 时间参数格式为 `YYYYMMDD`（如 20260205）
+4. 支持 CORS，可从浏览器前端直接调用
