What is OverRec?

OverRec is a Windows tool that draws a transparent overlay rectangle on your screen, always staying on top of other windows. It helps you resize any application window to an exact size, measure screen regions, and take precise screenshots.

What are the three drawing modes?

• Free Drawing Mode — drag to draw a rectangle of any size with your mouse.
• Docking Mode — snap to common preset resolutions (320×240, 640×480, 800×600, 1024×768, 1280×720, 1920×1080, and more).
• Fixed Coordinate Mode — type exact X, Y, width, and height values for pixel-perfect positioning.

How do I take a screenshot?

Click the screenshot button in the toolbar. The captured image is automatically copied to your clipboard, ready to paste anywhere instantly.

Does OverRec work with multiple monitors?

Yes. OverRec supports multiple monitors and the overlay rectangle can be placed on any of them.

Can I use OverRec from the command line?

Yes. OverRec includes a full CLI for automation and scripting:

OverRec.exe cli monitors
OverRec.exe cli draw --location 100,200 --size 1280x720
OverRec.exe cli screenshot --location 0,0 --size 1920x1080 --clipboard

Can AI agents use OverRec?

Yes. The CLI is designed for seamless integration with AI agents and automation tools. An AI agent can call OverRec to capture specific screen regions or draw overlays as part of a larger automated workflow — no GUI interaction required.

Does OverRec require an internet connection?

No. OverRec works entirely offline with no network connections required.
