Download CJK Workbench for Windows
This is the official CJK Workbench download, the original build for Windows 10 and 11. The setup program is about 34 MB, and a portable single .exe of about 25 MB also exists for version 2.9.22.
- Press Download CJK Workbench and save the file to your Downloads folder.
- Compute the file's SHA-256 checksum with the certutil command shown below and compare it with the published manifest.
- Run the setup program. If Windows SmartScreen warns you, choose More info, then Run anyway, but only after the checksum matches.
- Open CJK Workbench, connect a model, then choose the project folder that holds only your own files and practice material.
No account is needed. A cloud AI provider may charge separately for its API, and that bill is between you and the provider, not CJK Workbench. Use the app only on files you own or may lawfully analyse.
System requirements
CJK Workbench runs on Windows 10 and 11 as a 64-bit (x64) app. It needs a model to talk to: a cloud AI provider, a model running locally on your PC, or the built-in model. The interface is available in 13 languages.
Updates
When a new version is ready, the app shows an Update button. Press it. Version 2.9.22 was released on 28 Oct 2026, and newer releases arrive the same way.
Check the installer
certutil -hashfile "C:\Users\you\Downloads\<downloaded file>.exe" SHA256The installer is not code-signed yet, so compare this SHA-256 value with the one in the published manifest. Run the setup only if the two values match exactly. A mismatch means stop.
