Describe, don’t draw
Turn "an STM32 with USB-C power and an I2C sensor" into a wired, editable schematic in minutes.
Use case
Prompt to clean netlist.
Describe a circuit in plain English and get an editable schematic with real parts: the first step of a flow that continues into layout, simulation and manufacturing in the same app.
- Plain-English input
- Editable real schematic
- Straight into PCB layout

The problem
Schematic capture is the slow, mechanical part
- Placing symbols and wiring nets by hand is hours of repetitive work.
- A blank schematic gives you nowhere to anchor a new design.
- Conventions like decoupling and pull-ups are easy to forget by hand.
How ProtoFlow helps
A real schematic, not a picture
Symbols, named nets, and power flags you can move, rename, and edit, not a static diagram.
Checked before layout
Built-in ERC flags unconnected pins and electrical mistakes, so the first draft is reviewable, not random.
The same design, all the way to fab
Sync the schematic to the PCB editor, simulate blocks in SPICE, and generate Gerbers and JLCPCB files without re-exporting between tools. Export to KiCad or Altium when your team standardizes there.
From capture to board
- 1Describe
Describe it in plain English
State the board or block you want: MCU, peripherals, power rails, constraints, the way you would brief a teammate.
- 2Draft
Get an editable schematic
ProtoFlow assembles the schematic with real parts and wires the repetitive conventions. You review it, clear ERC, and simulate what matters in SPICE.
- 3Build
Lay out and manufacture
Sync to the PCB editor, route by hand or with the auto-router, clear DRC, and export Gerbers, drills and JLCPCB BOM/CPL. Or export to KiCad or Altium.
FAQ
Can I edit the result?
Yes, everything is editable. It is a starting schematic, not a sealed black box.
Does it route the board?
Yes. The schematic syncs to ProtoFlow's PCB editor, where you route tracks and vias by hand or run the auto-router, which has presets, layer filters and a completion summary. You review the result and clear DRC before release.
How do I avoid AI mistakes?
Run ERC, use real parts, simulate the blocks that matter, and verify key connections against the datasheet. You review and sign off before you fabricate.
