AI schematic generation
Describe a circuit or board block in plain language and get a drafted schematic instead of starting from a blank canvas.
ProtoFlow
Freemium
ProtoFlow is an AI-powered PCB design tool for electronics engineers, turning plain-English circuit ideas into editable schematics and a cleaner starting point for layout. Export to KiCad or Altium.
What is ProtoFlow?
ProtoFlow is an AI-powered PCB design tool focused on the early schematic stage. It helps engineers move from a plain-English idea to an editable schematic, a cleaner netlist, and a more workable starting point for layout.
The product is desktop-first and is presented as a companion to established EDA tools rather than a replacement. The site says you can draft with ProtoFlow, validate the result with built-in checks, and then export to KiCad or Altium for the rest of the PCB workflow.
What can ProtoFlow do?
Component discovery and import
Search for components from the built-in library and parts sources, then drag them into the schematic as real symbols and footprints.
Design validation
Check the draft with built-in DRC/ERC and connectivity analysis before exporting, so obvious wiring issues are caught earlier.
Git-based version control
Keep design work in sync with Git, including branching and visual diff overlays that show changes directly in the editor.
Collaboration and review
Collaborate in real time with multi-user editing, live cursors, comments, and threaded discussions for review.
Export and handoff
Export cleaned projects to KiCad, with docs also referencing Altium, Gerbers, BOM output, and manufacturing files.
Use Cases
“Prompt-based schematic capture”
Use ProtoFlow when you have a circuit idea in your head but want a starting schematic with real parts, named nets, and early wiring conventions already in place.
“Part discovery and symbol/footprint creation”
Use the component library and AI part generation when you need a symbol and footprint starting point from a part name, datasheet, or pinout reference.
“Cleanup and validation before export”
Use the built-in DRC/ERC and cleanup workflow to turn a rough first pass into a reviewable project before handing it off to your main EDA tool.
“Team review and versioned design work”
Use the collaboration, comments, Git, and diff features when more than one engineer needs to review or modify the same design.
“Onboarding and first project setup”
Use the docs and getting-started flow when you want to install the app, create a new schematic, and learn the editor basics quickly.
Frequently Asked Questions
What is ProtoFlow?
ProtoFlow is an AI-native desktop tool for turning a plain-English description into an editable schematic and a cleaner PCB starting point. It is aimed at electronics engineers who want to reduce the repetitive early work in schematic capture before moving into KiCad or Altium.
Does ProtoFlow replace KiCad or Altium?
No. ProtoFlow is positioned for the early drafting and setup stage, not as a replacement for KiCad or Altium. The workflow ends with export to those tools for final layout and routing.
Is ProtoFlow free?
Yes. The pricing page says ProtoFlow is free to start, with paid plans available for more AI help and higher limits. It also offers a 7-day free trial on new Pro subscriptions.
What platforms does ProtoFlow support?
ProtoFlow’s docs say it runs on macOS, Windows, and Linux. The getting-started guide lists macOS, Windows 10 or later, and Linux builds, with macOS support for Apple Silicon and Intel.
Can I use ProtoFlow for team projects?
The product is designed for desktop-first, local work and the FAQ says that helps keep work close to your machine and your team. The docs also describe real-time collaboration, comments, and Git integration as part of the workflow.
