Open-source tool that lets AI agents read vehicle diagnostic data through OBD-II adapters or simulated cars
About car-use
car-use is an open-source platform that enables AI agents to read and understand vehicle diagnostic data. Users can connect a real car via a $15 OBD-II adapter or use a virtual car to practice. The system reads error codes, live sensor readings and self-checks, then explains what's wrong in plain language. It works with Claude Code, Codex and other AI agents through a simple prompt. Beyond personal vehicles, car-use supports motorsport applications including go-karts, formula cars and track day racing, as well as fleet management for cranes, excavators, generators and trucks. The platform is designed to be safe by default, starting in read-only mode and only allowing additional functions with explicit user permission.
