OverRec FAQ
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.
How do I snap a window to an exact position?
Draw the rectangle where you want the window to go — use Fixed Coordinate Mode to type exact values, or Free Drawing Mode to drag it into place. Then click the Snap Window button (rightmost in the toolbar), search for your window by title, and click it. OverRec moves and resizes it instantly to fill the rectangle.
From the CLI:
OverRec.exe cli window chrome
OverRec.exe cli snap --windowid 657846 --location 0,0 --size 1280x720
How do I tile two windows side by side?
Use the CLI to snap each window to half the screen:
OverRec.exe cli snap --windowid 657846 --location 0,0 --size 960x1080
OverRec.exe cli snap --windowid 329812 --location 960,0 --size 960x1080
Or find both window IDs first:
LEFT=$(OverRec.exe cli window chrome | awk 'NR>2 && $1~/^[0-9]+$/ {print $1; exit}')
RIGHT=$(OverRec.exe cli window notepad | awk 'NR>2 && $1~/^[0-9]+$/ {print $1; exit}')
OverRec.exe cli snap --windowid "$LEFT" --location 0,0 --size 960x1080
OverRec.exe cli snap --windowid "$RIGHT" --location 960,0 --size 960x1080
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, snap windows into place, or draw overlays as part of a larger automated workflow — no GUI interaction required.
For Claude users, overrec-screen-skills provides ready-made MCP tools that wrap the OverRec CLI, letting Claude agents take screenshots, snap windows, and draw overlays directly.
Does OverRec require an internet connection?
No. OverRec works entirely offline with no network connections required.
What are the system requirements?
- Windows 10 or Windows 11
- No additional dependencies or software required
