+## 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 |
