Handler is the consolidated desktop product of Julian Utility Company. The downloads below come from the official GitHub release, and each archive has a published SHA-256 checksum you can verify before running it. Handler is early software, and this release is labeled alpha accordingly.
The integrity files for this release are SHA256SUMS.txt and PROVENANCE.txt. PROVENANCE.txt records the commit and tag the artifacts were built from.
Compare the hash of your download against the value printed above, or against SHA256SUMS.txt on the release page. On Windows, run this in a Command Prompt from your Downloads folder:
certutil -hashfile Handler-windows-x64.zip SHA256
On Linux, run:
sha256sum Handler-linux-x64.tar.gz
Windows. Extract the zip into a new folder. The archive does not contain a folder of its own, so extracting into a fresh directory keeps its files together. Start Handler by running Handler.exe.
Linux. Extract the archive and run the executable:
tar xzf Handler-linux-x64.tar.gz
./Handler/Handler
If your system reports that the file is not executable, run chmod +x Handler/Handler first.
Both builds are self-contained. They bundle the runtime Handler needs, so there is nothing else to install first.
This is an early development release. The current build includes the desktop shell, first-run configuration, clipboard capture, the radial workflow menu, Bento text transformations, original-text restore, and update checking.
Voice input, screen understanding, and general agent execution are in active development. They are announced on the homepage as designed capabilities, and they are not part of this build.
Platforms. Windows and Linux are supported today and are co-equal targets. macOS is planned once it can be tested on real hardware.
