ProtoFlow is an AI-powered PCB design tool that turns plain-English circuit ideas into editable schematics and cleaner starting points for layout. Desktop-first, with export to KiCad or Altium.

ProtoFlow

Overview

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.

Features

AI schematic generation

Describe a circuit or board block in plain language and get a drafted schematic instead of starting from a blank canvas.

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.

Pros and Cons

Pros

  • Turns a natural-language circuit description into an editable schematic starting point.
  • Includes built-in DRC/ERC, which helps catch simple drafting issues before export.
  • Supports desktop use on macOS, Windows, and Linux.
  • Documents real-time collaboration, comments, Git integration, and visual diff overlays.
  • Offers a free tier and separate paid plans for users who need more AI usage or larger limits.

Cons

  • It is not a full replacement for KiCad or Altium; final layout and routing still happen in the main EDA tool.
  • The source material does not fully document all supported integrations, file formats, or collaboration limits on the public pages reviewed.
  • Some advanced AI and team features are tied to paid plans or higher tiers.

FAQ

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.
