Software Usage Instructions

Start WeChat and log in: Before use, open and log in to the WeChat client on your computer, and make sure the local chat history is readable. The software relies on the running WeChat process to obtain the database key.
Set monitoring keywords: Enter the content you want to monitor in the "Keywords" input box. Multiple keywords are supported; separate them with a vertical bar "|" (for example: registration|shipping|payment collection). A reminder will be triggered when any one of them is matched.
Configure monitoring options:
- Automatically obtain key: When checked, the software will automatically try to obtain the WeChat database key, with no need to enter it manually
- Include messages sent by yourself: When checked, messages you send that match the keywords will also be recorded. This is unchecked by default
- Bottom-right reminder: When checked, a reminder window will pop up in the bottom-right corner of the screen when a keyword is matched
- Case sensitive: Choose whether keyword matching should distinguish uppercase and lowercase English letters as needed
Select account directory: The software automatically detects the WeChat account directory by default. If it cannot be detected, you can manually specify the corresponding account folder in xwechat_files.
Start monitoring: Click the "Start Monitoring" button. The software will first scan historical messages to complete the initial comparison, then enter real-time monitoring mode. The status bar will display the current progress and number of matches.
View and export records: Matched messages are automatically archived as CSV files by date, including fields such as chat window, sender, matched keyword, and message content. You can open the records directory at any time to view them or analyze them with spreadsheet software.

FAQ

A: Simply separate keywords with a vertical bar "|". For example, enter "registration|shipping|payment collection"; if any one of these words appears in a message, a reminder will be triggered. Extra spaces before and after each keyword will be automatically removed, and duplicate keywords will be automatically merged.

A: The software obtains chat history by reading the local WeChat database, and the database requires a key to be decoded. Only when WeChat is logged in and running can the software automatically obtain the key and read local records. Therefore, please make sure WeChat is open and logged in before use.

A: You can try the "Restart to Obtain" function in the software. After you click it, the software will close and restart WeChat. Follow the prompts to scan the QR code to log in or confirm the login. After login is complete, the key can be obtained automatically. Please make sure WeChat is installed on your computer and can be opened normally.

A: No. The software reads the local WeChat database. Keyword matching and record archiving are completed on your own computer. Chat content and matched records are saved in a local directory and will not be uploaded to any server. Your data remains under your control.

A: Real-time monitoring detects database changes, allowing new messages to be matched and alerts to be sent more quickly after they arrive. When real-time monitoring is unavailable in the current environment, the software automatically switches to scheduled checks that poll at fixed intervals. Keyword hit alerts can still be completed, but notifications may be slightly delayed.

A: Matched records are automatically saved by date as CSV files in the records folder under the software directory. They include fields such as record date, message time, chat window, sender, matched keyword, message content, and session ID, and can be opened directly in spreadsheet software such as Excel or WPS for viewing and statistics.

A: The software automatically detects common account directory locations by default. If it cannot be detected, you can manually specify the account folder in Settings. It is usually located in the corresponding account subdirectory inside the xwechat_files folder under the "Documents" directory. Once selected, it can be read normally.
