## Summary

A Japanese developer published a paid article describing a hardware method to let an AI model on one computer operate a second, isolated machine without installing software or using the cloud. The setup uses PC2 (which runs the AI) to capture PC1's screen over HDMI and send keyboard and mouse inputs to PC1 via USB, making the AI act as remote "eyes and hands." The author frames the approach as a way to bypass air-gap restrictions where only external display and input ports are permitted, and provides design blueprints, equipment guidance, a control loop, and seven Japanese-language prompts for Claude Code. The article omits the completed input-sending code for safety, requiring readers to build it themselves. It costs 980 yen and includes safeguards such as confirmation steps to prevent runaway actions.

## Key points

- AI on PC2 reads PC1 screen via HDMI capture and sends inputs over USB
- No software installed on target PC1 and no cloud connection used
- Article sells design, prompts, and safety guidance for 980 yen

## Why it matters

Shows a low-level hardware workaround that lets frontier models operate air-gapped systems, raising both productivity and security questions for isolated environments.
