Download Arraydeck and check the build before you run it
This is the official Arraydeck download of the original build. The button gives the setup program of about 34 MB for Windows 10 and 11, and the checksum steps below show you how to confirm that the file is the one that was published.
- Press Download Arraydeck. The browser saves the setup program of about 34 MB, and this website records the download as described on the privacy page, then redirects you to the installer. Keep the saved file in your Downloads folder until you have checked it.
- Compare the SHA-256 checksum of the saved file with the value in the published manifest. The command further down this page prints the checksum of the file you downloaded, so you can read the two values side by side. If they differ, delete the file and download it again.
- Run the setup program. Windows SmartScreen may warn you because the installer is not code-signed yet. Choose More info and then Run anyway, but only after the checksum matches the published value.
- Open Arraydeck, connect a model (a cloud AI provider, a model running on your PC or the built-in model) and choose the project folder that holds your .dpr and .pas files as the working folder. A first read-only request, such as a search for one procedure, is a safe way to see how the cards work.
No account is needed to run Arraydeck. A cloud AI provider may charge separately for its own service, and that billing is between you and the provider. The built-in model is ready to use without an endpoint of your own. Use Arraydeck only on projects you own or are allowed to change, and build and test every result yourself before you rely on it. Send long units to a cloud provider only when you accept its terms for that text.
System requirements
Arraydeck is for Windows 10 and 11 on a 64-bit (x64) PC. The setup program is about 34 MB, and the interface of the app comes in 13 languages. You also need a model: a cloud AI provider with its API endpoint and key, a model running locally on your PC, or the built-in model. Shell runs your own build and test commands, so the tools you already use to compile a project must be installed on the PC or on the server you connect to. Keep enough disk space for the setup program, for your projects and for the files the agent writes into the working folder.
How updates work
New versions are published automatically, and the app shows an Update button when one is ready. The installer build enables auto-updates. The current version is 2.9.30, released on 8 Nov 2026. The Update button appears only when a new version is ready. Press Update when it suits you, ideally between two tasks and not in the middle of a long run, because a restart interrupts the task that is open, and compare the version number shown in the app with the one on this page if you want to know whether you are current.
Check the file before you run it
certutil -hashfile "C:\Users\you\Downloads\<downloaded file>.exe" SHA256Open a Windows command prompt, replace the path with the real location and name of the file you downloaded, and run the command. It prints the SHA-256 checksum of that file. Compare it with the published manifest character by character, and stop if the two values differ. A mismatch means the file is not the published build, even if the download looked normal.
