## What it is
EchoTrace is a fully local, privacy-focused desktop application for exporting, decrypting, and analyzing WeChat chat records. It generates personalized annual reports and visualizations (word clouds, statistics) from your chat history, with export to shareable formats like HTML.

## Use cases
- export wechat chat history locally
- generate annual report from wechat chats
- analyze my wechat chat statistics
- create word cloud from chat messages
- decrypt wechat chat database
- share chat history as html
- see who I chat with most on wechat

## When to choose
- you want a fully local, offline tool with no data leaving your machine
- you want a visual annual report or word cloud from WeChat chats
- you want to export WeChat messages to shareable HTML

## When to avoid
- you need real-time chat features or ongoing maintenance - the project is no longer maintained (see WeFlow or Miyu alternatives)

- you need a server-side or multi-user analytics solution
