Chalkline for Windows and Linux.

Two builds, so it runs on both kinds of Windows PC: 64-bit for nearly everything made in the last decade, and 32-bit for the older machines still working hard in school labs. Windows 10 or later. Linux users get a single AppImage.

Most computers

Windows may warn you the first time. The 2.0.0 builds are not yet code-signed (signing is the first item on the roadmap), so SmartScreen can show “Windows protected your PC”. Choose More info → Run anyway, and check the SHA-256 above against your file if you want to be sure it is untouched.

Which one do I have?

Not sure if your PC is 32 or 64-bit?

Open Settings → System → AboutPress Win + I, then choose System and scroll to About.
Read “System type”It says either 64-bit operating system, x64-based processor or 32-bit operating system.
Pick the matching downloadWhen in doubt, try 64-bit — if your PC is 32-bit it will tell you it cannot run, and nothing is harmed.

Installer or portable?

Two ways to run it

Installer

Adds a Start-menu entry and a desktop shortcut and can be removed from Windows Settings. Best for your own computer.

Portable

A single .exe that needs no installation and no administrator rights. Put it on a USB stick or a shared folder; set CHALKLINE_DATA_DIR to keep boards beside it.

Your files

Boards are saved to Documents\Chalkline as ordinary .board files. Uninstalling never touches them.

Requirements

Runs on modest hardware

Operating system	Windows 10 or 11 (64-bit or 32-bit), or a 64-bit Linux desktop
Input	Mouse, pen or touch screen
Network	Not required. Only the optional online AI uses the internet.

Price	Free for teachers and schools
