In plain words
Copperhead is an open-source AI platform that automates PCB design, documentation, and validation from text prompts. It enables hardware teams to design and modify circuit boards using natural language commands, similar to how AI assists software development. The tool integrates with KiCad to generate schematics, validate electrical designs, and maintain documentation automatically.
