I found an open-source project that truly allows AI to "use its hands" to work

cua, 16.7k stars, not a chat robot, but the infrastructure that enables AI to directly control a computer
The core idea is simple: provide AI with a sandbox environment where it can click the mouse, type on the keyboard, and see the screen, allowing it to operate software like a human
Several subprojects have clear divisions of labor:
✅ Cua Driver: macOS background operation driver, AI clicks buttons and types without stealing your cursor, doesn't switch your window, silently works in the background
✅ Cua Sandbox: unified API control for Linux/macOS/Windows/Android, runs in the cloud or locally
✅ CuaBot: provides sandbox environments for coding agents like Claude Code and Cursor, ready to use out of the box
✅ Cua-Bench: benchmark tests to evaluate agent operation capabilities, runs datasets like OSWorld and ScreenSpot
✅ Lume: runs macOS virtual machines on Apple Silicon, performance close to native
Looking at the code, it's a mix of Rust, Swift, and Python, with a pretty hardcore architecture. If you're interested in agent automation, desktop task orchestration, or just curious about "how AI uses computers," this is worth checking out the source code
