【System Requirements】

Windows 10 / 11
Adobe Illustrator 2025 or later recommended
(Designed to work with earlier versions such as 2024 and before, but these environments are not available for verification.)

【Features】

Easy drag‑and‑drop script registration
No Illustrator restart required. Registered scripts can be executed immediately.
Centralized script management
No migration needed when switching between Illustrator versions.
Run scripts with keyboard shortcuts
Supports modifier key + main key, or main key alone (without interfering with text input).
Keep the launcher completely hidden
You can run shortcuts even while the launcher is fully hidden, so it never takes up workspace.
Pass arguments to scripts
Create input UI on the launcher with simple tag notation.
The launcher also manages user‑entered values, so scripts no longer need their own save/load handling.
Optional helper utilities for Illustrator
Convenient assistive functions you can turn on or off at any time.
Add notes to each script
Never forget what a script does — keep quick notes right inside the launcher.
Automatic update checks

【About Creating Argument Input UI】

By adding comment-based tags to your script, you can create argument input fields in the launcher and pass their values as arguments when the script is executed.

The launcher also saves these values, so you don’t need to implement your own save/load logic in the script when you want to preserve user settings.

Example: To create the following three input fields on the launcher:

Type: number / Label: "Offset" / Default: 0.000
Type: string / Label: "Unit" / Default: "px" / Format: dropdown
Type: boolean / Label: "Ignore Stroke width" / Default: false

Add these comments at the top of your script as instructions to the launcher:

// #IC_param {number} "Offset" 0.000// #IC_param {string} "Unit" "px" ["px", "mm", "%"]// #IC_param {bool} "Ignore Stroke width" false

To receive these values when the script is executed, use:

var arg_offset = arguments[0];var arg_unit = arguments[1];var arg_ignoreStroke = arguments[2];

That’s all there is to it.

For more details—such as how to make your script work even when run outside this app (e.g., by assigning fallback values when no arguments are provided), or how to embed help text displayed in the launcher—see "Explaining-Parameter-Tags-Demo.jsx" in the SampleScripts folder.

All bundled sample scripts are plain text, so you can open them in any text editor and use them as references for defining and retrieving arguments.

【Notes】

To run scripts that use the #include directive, all required external files must be placed in the correct relative paths, starting from the launcher's script management folder.

*The management folder is the "scripts" folder inside the location opened via "Open save data folder" in the main menu.

This tool may not work correctly depending on changes in Adobe Illustrator versions or specifications.
If you are considering purchasing the EX edition, we recommend using the trial mode of the EX features included in the free standard edition to verify that it works properly in your environment.

【Known Issues (Fixes Planned)】

✅Fixed The launcher layout may break when the system display scaling is set to values other than 100%
✅Fixed If an update notification appears at startup and you update to the latest version, the notification will continue to appear for up to 10 minutes. Launching the latest version again after more than 10 minutes will stop the notification.
✅Fixed Due to the method used to send scripts from the launcher to Illustrator, some jsxbin scripts may produce errors at runtime
✅Fixed When dragging scripts while a category filter is active, the drop position indicator may be incorrect
