What is crosshair-studio-engine?

Crosshair-Custom-Overlay-Games, described in the repository as Crosshair Studio Engine, is a tool that draws a customizable crosshair overlay on top of any game or application window. Instead of being tied to one game's built in reticle options, it works as a transparent layer that sits above whatever window or fullscreen game you are running, so you can add a custom crosshair to titles that do not offer one. You can configure the crosshair's shape, thickness, gap, length, and color, and set up conditional behavior such as the crosshair shrinking when you move, expanding when firing, or changing color based on ammo or proximity settings you define. Profiles are stored as JSON files and can be loaded through a command line interface or a graphical configurator, and the tool supports hotkeys for reloading configuration without restarting. The README describes an optional AI layer using the OpenAI and Claude APIs, which is opt in and off by default, letting you generate a crosshair configuration from a natural language description or analyze locally recorded gameplay footage for suggested adjustments. The README states no telemetry is collected without consent and that cloud analysis is disabled unless a user turns it on. It runs on Windows 10 and 11 with full support, Linux with X11 or Wayland, and macOS in beta with partial Metal API support. Android support through Termux is described as experimental, and the Steam Deck is listed as optimized. The README states the interface supports six languages and scales to different screen sizes and resolutions.
