Download the desktop build directly, no account or email needed. Start with synthetic examples before connecting a working API.
Use Windows 10/11 x64 or Linux x64 with a graphical desktop. The Java runtime is included in the archive. The phone-friendly website lets you read examples, but running the application requires a supported computer.
The full Windows archive with local AI is around 1.2 GB. Your account shows the exact size of the current build. Leave room for both the archive and its extracted folder. Local AI speed depends on CPU and memory; measured minimum requirements for AI have not been published.
No sign-up or email needed. Internet is needed for the first launch and occasionally for the license check. Your requests, responses and logs never leave the computer. On Windows, the 7z archive can be extracted with the free 7-Zip.
Downloads in a couple of minutes. Add the local AI later from the app with one button.

AI works offline from the first launch. Takes longer to download.

For desktop distributions: Ubuntu 22.04 and 24.04.
Checkcraft-Portable-Linux.tgzSHA-256:
On first launch, click Start for free and accept the license agreement. Bought Pro? Open File → Upgrade to Pro in the app and sign in to your account.
Extract the whole Windows archive and open Checkcraft.exe from the extracted folder. Keep the bundled runtime and library folders alongside the executable.
For Linux, download the tgz archive and follow its included launch instructions.
If Windows shows a warning. The “Windows protected your PC” or “Unknown publisher” window appears for new programs without a digital signature. Checkcraft is not signed yet, so Windows cannot name the publisher. That is what the warning reports, not that a virus was found in the file. Whether it appears also depends on the tool used to extract the archive. You can compare the file with the SHA-256 checksum next to the download button, or ask us in Telegram.
Use RU / EN on the sign-in screen or main window to choose the interface language. The app saves your choice and applies it after restart. Save open work before restarting. The language setting does not translate your requests, JSON values or saved rule identifiers.
Follow the first no-code test guide and run both the valid and broken input. You can create and execute ordinary checks without asking the local AI model to generate anything.
Separate archives are published for Windows 10 and 11 x64 and Linux x64. On Ubuntu, verify the Linux build requirements. Portable means launching from an extracted directory, not a Chrome or Firefox extension or a VS Code or IntelliJ IDEA plugin. A Linux archive does not establish macOS compatibility. Available builds and their sizes are listed on the download page.
