About

Copperhead is an open source AI engineering platform that helps hardware teams design, verify, and ship circuit boards. You describe a change or provide a product brief, and the agent edits real KiCad files, updates the documents that reference them, and runs KiCad’s own checks until they pass. Its end-to-end workflow moves through specification, architecture, parts selection, schematic, layout, outputs, firmware, and development planning, with each stage required to leave a real artifact on disk before the next begins. Gates verify budgets, subsystem reasoning, datasheet-backed part numbers, ERC-clean schematics, DRC-clean layouts, generated Gerbers, firmware sources, and written bring-up plans. Copperhead is also designed for existing boards: point it at a KiCad repository, initialize the project, and ask for changes. Edits are surgical changes to KiCad source files, keeping diffs small and reviewable while untouched portions remain unchanged.

About

ProtoFlow is an AI-native desktop electronic design automation (EDA) tool for schematic capture and PCB design. Describe a circuit in plain language to create an editable first draft, search real electronic parts and footprints, inspect datasheets, clean up wiring, and continue manually in familiar schematic and board editors. ProtoFlow supports ERC/DRC review, 3D board inspection, Git-backed versioning and visual diffs, comments and collaboration, plus manufacturing outputs including Gerber, drill, BOM, and placement files. Designs remain normal editable geometry, and users should verify symbols, footprints, connections, and manufacturing data before production. ProtoFlow can read and write native KiCad files and export to established EDA workflows. A free plan is available without a credit card, with paid options for higher AI usage. It is built for hardware engineers, makers, students, educators, researchers, and electronics startups.
