J-AST Help

Desktop application

The J-AST desktop application is a standalone program that runs entirely on your local machine. It bundles a Java 21 runtime and the JIPipe image processing engine, so no additional software needs to be installed.

Where your data is stored

The desktop application stores all data — including the H2 database, uploaded images, and temporary processing files — within the application directory under a storage/ subfolder.

Updating J-AST

To update J-AST, download the latest version from the website and replace the old installation. Your data in the storage/ directory will be preserved if you keep it in the same location.
