PCBEditor vs ProtoFlow
Both generate circuits from AI. The real difference is how much of the board each one finishes — schematic capture versus schematic through routed copper.
ProtoFlow is an AI-native schematic tool with an IDE-style interface, built around fast part sourcing: it searches DigiKey, LCSC and Mouser, pulls pinouts and footprints into the workspace, keeps files local, and exports to KiCad. Its focus is the schematic half of PCB design, and it is good at it.
PCBEditor covers the same schematic step but carries the design further in one place — placement, deterministic multi-layer routing, design-rule checking and fabrication export. If your layout already lives in KiCad and you want a better front end for schematic capture and sourcing, ProtoFlow fits well. If you want to reach routed copper and Gerbers without changing tools, that is what PCBEditor is built for.

Pick PCBEditor when
- ✓You want to go from a description all the way to routed copper and fabrication files in one tool.
- ✓You need placement, autorouting and DRC, not just the schematic.
- ✓You are working on a device without a desktop EDA install — a phone, tablet or Chromebook.
Pick ProtoFlow when
- –Your priority is fast part sourcing across DigiKey, LCSC and Mouser while you draw.
- –You want design files kept local rather than in the cloud.
- –You already lay out and route in KiCad and only want a better schematic front end.
