EchoTrace is a completely local, secure software tool designed for exporting, analyzing, and generating annual reports from WeChat chat records. By decrypting local databases, it allows users to view chat histories offline without uploading personal data to any external server, ensuring privacy and security. The application enables users to export conversations into formats like HTML for easy viewing or sharing, facilitating offline backups of important communications. Beyond simple export, EchoTrace provides deep analytical capabilities to transform raw chat data into meaningful insights. Users can generate unique annual reports that reveal communication patterns, such as the total number of messages exchanged, interaction frequency over time, and the most common words used in conversations. The tool also supports specific pair analysis, offering statistics on when two individuals communicate most frequently and the evolving nature of their relationship timeline.
