Weixin AI Assistant

Get started

1. Sign in with your verified JYI account on this page; once you are signed in, this page shows the current download button. Future versions do not require getting access again.
2. On Windows 10/11 x64, save the ZIP file to a writable local folder and choose “Extract All”. Do not run the app from the archive preview.
3. Keep the extracted folder structure intact. Open the folder and double-click “启动威信AI智能助理.bat”. Start and sign in to the Windows desktop WeChat app first.
4. On first launch, sign in with the JYI OAuth account you enabled access with. Internet access is required for authorization and update checks.

Before you start

Current JYI portable package: Windows 10 or 11, 64-bit x64. This is an x64 build; 32-bit Windows, Windows on ARM, macOS and Linux have not been validated. Enterprise WeChat is not supported. Project documentation lists WeChat Desktop 3.9.12.x and 4.1.6+ for different modules; this does not mean every feature works on every version. Some WeChat 4.x accounts may not expose the UI Automation tree. The launcher first looks for a bundled runtime, then tries the Windows Python launcher or Python on PATH; if it reports Python missing, Python 3.10+ is required. Keep the app folder writable. Internet access is required for JYI OAuth access and update checks.

Permissions

We recommend running this tool with a secondary WeChat account; any account risk arising from the use of this tool is borne by the user.

Usage guide

Troubleshooting 1. If the client reports that access is not enabled or the download is unavailable, sign in again on the product page and download the installer from this page; if it still fails, contact JYI to check your access status. 2. If the launcher reports that Python is missing, contact JYI to confirm the package. Python 3.10 or later may be required if no runtime is bundled. Data and updates The app stores data in the data folder inside the app directory. Close the app before backup or migration, then copy the entire app directory. Once enabled, the desktop client uses the same JYI OAuth account for automatic updates; new versions do not require getting access again.

How data is handled

Data & permissions notice: when you click 提取密钥 (Extract key), this tool reads WeChat's process memory to obtain the decryption key of your local WeChat database. The key is stored only on your computer (encrypted with Windows DPAPI) and is used for nothing else. Chat history is read from the local WeChat database on your PC; decrypted copies stay local and are deleted after use. When you run AI analysis, the text of the messages you selected (and images, where the model supports them) is sent to JYI's AI gateway to produce the report. Nothing else about you is uploaded.
