ProtoFlow

Introduction

ProtoFlow is an AI-native desktop PCB design tool for Windows, macOS and Linux that helps engineers go from idea to a clean PCB faster. Describe your circuit in plain language and AI drafts the schematic, places real parts and cleans up wiring. You can then lay out the board in-app, run DRC / ERC checks, preview it in 3D, and export manufacturing files such as Gerbers, drill files and BOMs, or hand the project to KiCad or Altium for deeper work.

Features

• AI natural language schematic generation
• Smart component search and placement (real parts from LCSC / DigiKey / Mouser)
• Automatic schematic cleanup
• Built-in PCB editor with routing, vias and copper zones
• DRC / ERC electrical and design rule checks
• 3D board viewer
• Manufacturing file export (Gerber, drill files, BOM / CPL)
• Export to KiCad / Altium for deeper design work
• Real-time collaboration, comments and Git version control
• Available for Windows / macOS / Linux, free to start
