## What it is
A desktop application that decrypts WeChat 4.x's encrypted local databases (SQLCipher/WCDB) by scanning memory for the key, then lets users browse, search, edit, and export chat history, Moments, and favorites in a WeChat-like interface. It runs 100% locally, generates animated annual summary reports, and exposes an MCP server so AI assistants can query the message archive.

## Use cases
- decrypt wechat chat database
- export wechat chat history to files
- generate wechat annual summary wrapped
- view wechat moments and favorites offline
- search and edit old wechat messages
- let an AI assistant query my wechat messages via mcp
- back up wechat data before uninstalling wechat

## When to choose
- you want to recover and read your own WeChat 4.x data locally with zero cloud upload
- you need a polished, WeChat-faithful viewer with export, editing, and real-time message sync
- you want shareable annual chat statistics and wrapped-style summaries

## When to avoid
- you need to decrypt QQ or other messaging platforms (this targets WeChat 4.x only)
- you require a signed, formally licensed build - the repo currently has no license file
- you need a headless CLI-only pipeline rather than a GUI desktop app
- you intend to access someone else's account data, which is outside the tool's intended and legal use
