MAC系统 获取微信聊天记录 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
本项目的目标,是在自己的电脑上实现“本地查看微信聊天记录 + 一键生成群聊总结”的实用能力。
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。
## ✨ 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。
- **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。
- **实用信息与资源**: 提取分享的链接、资源等信息。
- **重要消息汇总**: 标记并展示重要消息,带发送者头像。
- **有趣对话或金句**: 收录群内的精彩对话。
- **问题与解答**: 整理群内的问答内容。
- **群内数据可视化**: 消息热度条形图、话唠榜 TOP5、活跃时间线。
- **词云/关键词**: 可视化展示群聊关键词。
- **图片生成**: 将 AI 总结的内容生成精美图片,方便分享。
- **数据导出**: 支持导出聊天记录为 CSV 文件(今日、昨日、近7天或全部)。
- **安全隐私**: 所有数据仅在本地处理,AI 功能需自行配置 API Key。

## 🚀 快速开始
### 使用前置要求
- **微信版本**: 推荐使用微信 **4.0 以下**版本(4.0以上版本不支持数据库解密)
- **微信版本**:
- 微信 <= 4.0: 可正常使用,获取数据库密码方式参考:[Mac 导出微信聊天记录](https://blog.vcvit.me/2024/08/02/mac-export-wechat-chat-records/)
- 微信 >= 4.0: 可正常使用 (正在迭代) ,推荐使用 [WeFlow](https://github.com/hicccc77/WeFlow) [Chatlog](https://github.com/sjzar/chatlog)
- 微信 >= 4.0: 已支持部分能力,仍在持续迭代与兼容性验证中;如需更成熟的完整方案,推荐使用 [WeFlow](https://github.com/hicccc77/WeFlow) [Chatlog](https://github.com/sjzar/chatlog)
- 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
