ProtoFlow

ProtoFlow is an AI-powered PCB design tool for early schematic drafting, part setup, cleanup, and export on Windows, macOS, and Linux.

ProtoFlow

Overview

ProtoFlow is an AI-powered PCB design tool that helps hardware engineers get past the blank-schematic stage faster. It is positioned as an AI-native desktop companion for early EDA work, including schematic generation, component import, cleanup, and export into tools like KiCad and Altium.

The site describes a workflow where you explain the board or block in plain language, let ProtoFlow draft and clean up the first pass, and then continue layout in your main EDA environment. The product is available as a desktop app for Windows, macOS, and Linux, and the documentation highlights built-in DRC/ERC, collaboration, Git integration, and additional PCB editing tools.

Core features

AI schematic generation

Describe a circuit in plain language and have ProtoFlow assemble an editable first pass instead of starting from a blank schematic.

Component and part discovery

Search for parts from one place and drag components into the schematic, with the docs calling out built-in access to LCSC and support for DigiKey and Mouser in the docs pages.

Design validation

Run built-in DRC/ERC checks to catch unconnected pins and electrical mistakes before export, so the first draft is reviewable.

EDA export handoff

Export the project to KiCad, and the use-case page also mentions Altium handoff for layout work in your main EDA tool.

Desktop PCB workspace

Work in a desktop editor with docking panels, tabs, themes, comments, live collaboration, and Git integration.

AI part creation

Generate linked symbols and footprints from a part name, datasheet, or pinout image using the AI Component Lab and part generator tools.

Common use cases

  • Prompt-to-schematic drafting

    Start from a sentence like a board block, MCU setup, or power rail description and get a wired first pass that is editable rather than just a static image.

  • Part discovery and symbol setup

    Search for real parts, create linked symbols and footprints, and bring components into the design without jumping between datasheets and catalog tabs.

  • Cleanup before handoff

    Run DRC/ERC on the draft, clean up the result, and export a tidier project into KiCad or Altium for detailed layout and routing.

  • Team review and versioned work

    Use comments, live collaboration, and Git integration when several engineers need to review or edit the same schematic workspace.

  • Cross-platform desktop drafting

    Open the desktop app on Windows, macOS, or Linux and use the interface for early-stage schematic capture without moving straight into full PCB layout.

Pros and Cons

Pros

  • Turns a plain-English circuit description into an editable schematic starting point.
  • Includes built-in DRC/ERC and cleanup tools to make drafts easier to review.
  • Supports desktop use on Windows, macOS, and Linux.
  • Offers collaboration, comments, and Git-based versioning in the editor.
  • Provides a free tier and paid plans for larger AI allowances and advanced models.

Cons

  • ProtoFlow is not a full replacement for KiCad or Altium; the site frames it as a front-end for early drafting and setup.
  • Some advanced capabilities and higher usage limits are tied to paid plans.
  • The public pages do not fully spell out every integration or export format, so some workflow details require checking the docs.

FAQ

What is ProtoFlow?

ProtoFlow is an AI-native desktop tool for getting from an idea to a cleaner PCB starting point faster. It focuses on early schematic drafting and setup rather than replacing your main EDA flow.

Does ProtoFlow replace KiCad or Altium?

No. The site says ProtoFlow is built for the early drafting and setup work before the deeper layout steps you still do in KiCad or Altium.

Is ProtoFlow free?

Yes. The homepage says it is free to start, and the pricing page shows a Free plan with a full PCB editor and basic AI access, plus paid plans for higher limits and more AI capacity.

What platforms does ProtoFlow support?

ProtoFlow is available for Windows, macOS, and Linux. The docs list macOS (Apple Silicon and Intel), Windows 10 or later, and Linux builds.

Can teams use ProtoFlow together?

Yes. The documentation lists collaboration features such as live multi-user editing, comments and reviews, and Git integration.
