Project Overview

WeChat CLI is a WeChat data query and export tool designed for individual and enterprise users. All data is processed entirely on your local machine — nothing is uploaded to any server — making it ideal for operations, sales, and research teams needing to archive, search, and analyze chat history.

Problems Solved

• WeChat chat history is scattered across multiple devices, making centralized search and archiving difficult.
• Critical conversations, files, and decision records lack unified backup.
• Business teams want to perform customer analysis or operational retrospectives using historical chats, but lack an efficient, reliable tool.

Use Cases

• Chat Archiving: Regularly export and back up important customer or project group conversations.
• Keyword Search: Quickly locate historical messages by time range, keyword, or sender.
• Operations Analytics: Analyze peak activity hours, top contributors, and message distribution to support data-driven decision-making.
• AI Tool Integration: Export structured data (e.g., JSON) as input for intelligent assistants or LLM agents.

Key Features

• 100% local processing — full privacy control and zero cloud exposure.
• Multi-dimensional queries: chats, contacts, group members, favorites, and more.
• Flexible filtering by time or keyword, with export to Markdown, plain text, and other common formats.
• Install-and-run experience — supports macOS, Windows, and Linux.
