ProtoFlow
ProtoFlow is an AI-native desktop tool for accelerating the early stages of PCB design. It lets users describe a board or circuit in plain language, drafts a first-pass schematic with AI assistance, places key parts and cleans up repetitive wiring work, and exports a tidier project to mainstream EDA tools (KiCad or Altium). The product is positioned for hardware engineers, makers, students, startups, educators, and researchers and is free to start with optional paid plans for higher AI usage and limits. The site emphasizes a desktop-first workflow (Get for Mac) designed to keep work local and collaborative features such as live collaboration and Git integration.
