 # WechatExplorer
 
-MAC系统 获取微信聊天记录 AI一键生成群聊总结
+macOS / Windows 微信聊天记录查看，AI 一键生成群聊总结。
 是一个基于 Electron + React + TypeScript 开发的微信聊天记录查看与分析工具。它支持查看解密后的微信数据库内容，提供聊天记录搜索、导出以及 AI 智能总结功能。
 
 ## 项目说明
@@ -9,17 +9,23 @@ MAC系统 获取微信聊天记录 AI一键生成群聊总结
 
 在微信 4.0 数据库解析、解密思路上，项目参考了 [WeFlow](https://github.com/hicccc77/WeFlow) 等开源项目的实现方式；此项目围绕我自己的使用场景做的定制化工具，重点放在本地聊天记录查看、群聊总结和个人工作流集成上。
 
+> macOS 支持相对稳定；Windows 已初步支持 但因聊天记录大/机械硬盘等问题 会有所卡顿，仍在持续兼容不同微信版本与本地目录结构。
+
 ## ✨ 功能特性
 
 - **聊天记录查看**: 浏览微信好友和群聊的聊天记录，支持头像显示。
 - **全局搜索**: 快速搜索聊天内容。
+- **消息防撤回**: 高亮查看对方已撤回消息
 - **AI 智能总结**: 支持多模型服务配置（DeepSeek/GPT-4o/Claude/Moonshot），一键总结群聊精华内容，生成话题报告。
 - **群聊日报生成**: 支持围绕群聊内容生成日报，通常会覆盖以下模块中的部分或全部内容：
   - **今日讨论热点**: 梳理群内主要话题，支持热度标签。
+  - **一句话速览**: 首屏突出今日核心结论与待跟进事项。
   - **实用信息与资源**: 提取分享的链接、资源等信息。

-- 如无法获取本地数据库密码，则无法使用当前项目
-- Node.js (推荐 v16+)
-- pnpm@7
-- 解密后的微信数据库文件 (`.db`) 和对应的密钥
-- AI API Key（支持 OpenAI 兼容 API，可选 DeepSeek/GPT/Claude/Moonshot 等）
+> 微信 4.0+ 在 macOS / Windows 上已支持部分能力，目前仍在持续适配。如需其他成熟方案，也可参考 [WeFlow](https://github.com/hicccc77/WeFlow) 和 [Chatlog](https://github.com/sjzar/chatlog)。

+# macOS 关闭 SIP 教程
+
+SIP（System Integrity Protection，系统完整性保护）是 macOS 的系统安全机制。关闭 SIP 会降低系统安全性，只建议在确实需要读取或调试本地微信数据时临时关闭；操作完成后，建议重新开启。
+
+## 准备
+
+- 一台 Mac 电脑，Intel 芯片和 Apple Silicon 芯片均可。
+- 需要进入 macOS 恢复模式。
+- 请先保存正在编辑的文件，并预留一次重启时间。
+
+## 关闭 SIP
+
+### Intel Mac
+
+1. 关机。
+2. 按下开机键后，立刻按住 `Command + R`。
+3. 保持按住，直到进入 macOS 恢复模式。
+
+### Apple Silicon Mac（M1/M2/M3/M4）
+
+1. 关机。
+2. 长按开机键不放。
+3. 直到出现启动选项界面后松开。
+4. 选择“选项”，进入 macOS 恢复模式。
+
+### 在恢复模式中执行命令
+
+1. 进入恢复模式后，点击顶部菜单栏的 **Utilities（实用工具）**。
+2. 选择 **Terminal（终端）**。
+3. 在终端中输入：
+
+```bash
+csrutil disable
+```
+
+4. 按回车执行。
+5. 看到关闭成功提示后，重启电脑。
+
+## 重新开启 SIP
+
+如果后续不再需要关闭 SIP，建议重新进入恢复模式，在终端中执行：
+
+```bash
+csrutil enable
+```
+
+然后重启电脑。

+# WechatExplorer 使用教程
+
+本文介绍如何安装 WechatExplorer、自动获取微信数据库密钥，并完成首次连接。
+
+## 1. 使用前准备
+
+### 支持的版本
+
+| 系统 | 已测试的微信版本 | 说明 |
+| --- | --- | --- |
+| macOS | `4.1.8.100` | 支持相对稳定；自动获取密钥前需要关闭 SIP |
+| Windows | `4.1.9.57` | 已初步支持；不同安装路径和数据目录可能仍需手动调整 |
+
+- macOS 微信下载：[wechat-versions v4.1.8.100](https://github.com/zsbai/wechat-versions/releases/tag/4.1.8.100)
+- Windows 微信下载：[wechat-win-archive v4.1.9.57](https://github.com/iibob/wechat-win-archive/releases#release-v4.1.9.57)
+- WechatExplorer 下载：[GitHub Releases](https://github.com/Wxw-Gu/WechatExplorer/releases)
+
+> [!IMPORTANT]
+> WechatExplorer 必须取得本机微信数据库密钥才能读取聊天记录。请仅处理你有权访问的数据。
+
+### macOS：关闭 SIP
+
+macOS 自动获取密钥前需要关闭 SIP，具体操作见 [macOS 关闭 SIP 教程](../mac-disable-sip.md)。
+
+关闭 SIP 会降低系统安全性。建议了解风险后再操作，并在不再需要自动获取密钥时重新开启。
+
+## 2. 安装 WechatExplorer
+
+### macOS
+
+1. 从 Releases 下载 `.dmg` 文件。
+2. 打开 DMG，将 WechatExplorer 拖入“应用程序”文件夹。
+3. 如果系统提示“无法打开，因为开发者无法验证”，请前往“系统设置 → 隐私与安全性”，点击“仍要打开”。
+4. 如果系统提示应用已损坏，在终端执行：
+
+   ```bash
+   xattr -cr "/Applications/WechatExplorer.app"
+   ```
+
+### Windows
+
+1. 从 Releases 下载 `-setup.exe` 安装包。
+2. 双击安装，并按安装向导完成操作。
+
+## 3. 自动获取密钥
+
+### 第一步：确认微信数据目录
+
+启动 WechatExplorer 后，先检查页面中的“存储路径”是否正确。
+
+![确认微信数据目录](./images/initial-setup.png)
+
+Windows 当前不会扫描二级目录。如果没有正确识别微信数据，请进入“设置”，手动选择微信数据所在目录。
+
+![Windows 自定义数据目录](./images/windows-data-path.png)
+
+### 第二步：让微信停留在登录页面
+
+如果微信已经登录，请先退出登录；然后重新打开微信，让它停留在未登录页面，暂时不要点击登录。
+
+![微信未登录页面](./images/wechat-login-window.png)
+
+### 第三步：开始获取密钥
+
+返回 WechatExplorer，点击“自动获取密钥”。
+
+- **Windows**：看到“Hook 注入成功”后，返回微信完成登录。
+- **macOS**：系统会弹出授权提示，请输入当前 macOS 用户密码并完成授权，然后返回微信完成登录。
+
+![macOS 授权页面](./images/macos-authorization.png)
+
+> 点击“自动获取密钥”前，微信必须停留在登录页面。WechatExplorer 提示可以登录后，再回到微信完成登录。
+
+### 第四步：完成连接
+
+如果系统环境和微信版本符合要求，WechatExplorer 会自动填写数据库密钥并连接数据库。连接成功后即可查看、搜索和导出聊天记录，也可以配置 AI 服务生成群聊总结。
+
+![密钥获取完成](./images/setup-complete.png)
+
+## 4. 图片解密密钥
+
+微信 4.0 及以上版本的图片通常以 `.dat` 文件存储，显示图片还需要：
+
+- **XOR Key**：单字节十六进制值，例如 `0x40`。
+- **AES Key**：用于 AES-128-ECB 解密的 16 字符字符串。
+
+可以通过以下方式配置：
+
+1. 使用首次连接页面的“自动获取密钥”。
+2. 在“设置 → 图片解密密钥”中自动获取或手动填写。
+3. 从 WeFlow 或 Chatlog 的设置中导出后手动填写。
+
+数据库连接成功但图片无法显示时，请优先检查这两项密钥。
+
+## 5. 常见问题
+
+### 自动获取密钥失败
+
+请依次确认：
+
+1. 微信版本是否与上方已测试版本一致。
+2. 点击“自动获取密钥”时，微信是否停留在未登录页面。
+3. 微信数据目录是否正确；Windows 用户尤其需要检查是否多选或少选了一层目录。
+4. macOS 是否已按教程关闭 SIP，并完成系统授权。
+5. 微信和 WechatExplorer 是否都保持运行。
+
+仍然失败时，可以切换到“手动输入”，粘贴从其他兼容工具中取得的数据库密钥。
+
+### Windows 使用时卡顿
+
+Windows 支持仍处于初步阶段，不同微信版本、安装路径、数据目录和权限环境可能存在差异。建议优先使用上方已测试的微信版本。
+
+### 数据会上传吗？
+
+聊天数据库在本机读取和处理。只有使用 AI 总结功能时，相关聊天内容才会按你配置的模型服务发送；是否启用以及使用哪个服务由你决定。
+
+## 6. 下一步
+
+- 在应用“设置”中填写兼容 OpenAI API 的模型服务和 API Key，使用 AI 总结功能。
+- 在应用的 **API** 页面安装 Reader Skill，让 Codex 或 Claude Code 读取和总结本地群聊。
+- 本地 API 的端点和调试方法见项目 [README](../../README.md#ai-集成本地-http-api)。

+# WechatExplorer WeChat Connector
+
+This repository-local service provides the minimal WeChat bridge required by WechatExplorer:
+
+- QR-code login with a single persisted credential
+- account discovery
+- inbound long polling and authenticated webhook delivery
+- local HTTP health and send endpoints
+- text and local/remote media sending
+
+The executable is managed by the Electron main process. It is not a general-purpose agent runtime and does not load external AI command-line tools.
+
+## Commands
+
+```bash
+go run . login --json
+go run . accounts --json
+go run . start --foreground --api-addr 127.0.0.1:18011 --account-id <account-id>
+```
+
+Credential and synchronization state is stored under `~/.wechatexplorer/wechat-connector/accounts`. A successful login is written before the older credential and synchronization state are removed, so an incomplete login cannot destroy the last working credential.
+
+## Attribution
+
+Low-level protocol and media transport portions are distributed under the MIT license in [LICENSE](LICENSE). WechatExplorer-specific process management, webhook contract, product UI, and Agent Hub behavior live in the surrounding WechatExplorer project.
