EchoTrace is a local tool for exporting, analyzing, and generating annual reports from WeChat chat records.
The tool solves the problem of accessing and understanding WeChat conversation history by decrypting chat records and storing them locally for offline viewing. It works by extracting messages from WeChat's encrypted database, then analyzing the data to generate visualizations and annual reports that show conversation patterns, message frequency, and word clouds between users. Users can export their chat history as HTML to share with friends or keep reports private on their device.
EchoTrace suits anyone who wants to review their WeChat conversations without relying on WeChat's built-in search or storage limitations, and who values keeping their data local rather than uploading it to external services. The tool is particularly useful for generating reflective year-end reports that highlight conversation milestones with specific contacts. Those seeking deeper analysis of exported chat content may want to explore complementary tools, and users should be aware that the project is no longer actively maintained, with alternatives available for real-time functionality and backup features.
The project shows minimal recent development activity, with no ongoing commits or updates to address issues or implement planned features. The README indicates the project has entered a maintenance-free state, and the maintainers have explicitly recommended users explore successor projects for continued support.
