OverRec is an all-in-one screenshot tool, screen recorder, and window manager for Windows. Draw a precise overlay rectangle anywhere on screen, capture pixel-perfect screenshots, record any region to GIF, animated WebP, or MP4, and snap any app window to an exact size and position — from the toolbar, the command line, or an AI agent. A floating overlay rectangle always shows its live position and size, so everything you capture, record, and arrange is measured to the pixel.
