Say it in plain English
"An ESP32 with a USB-C input and an I2C sensor" becomes a wired schematic you can edit, not a blank grid.
For makers
Idea to board in an evening.
Describe the thing you want to build, get a real, editable schematic with orderable parts, then lay out the board and export Gerbers in the same free app. No EDA black belt required.
- Free to start
- Plain-English capture
- Gerbers & JLCPCB files

The problem
The tool should not be the hard part
- Traditional EDA has a brutal learning curve for a weekend build.
- Figuring out which parts exist, and which you can actually buy, is half the battle.
- You want to build the project, not fight symbol libraries.
How ProtoFlow helps
Parts you can actually order
Search across distributors in one place and drop in real parts with the right footprints.
Free, all the way to Gerbers
The free plan includes the full editor: lay out the board, clear DRC, and export Gerbers, drills and JLCPCB BOM/CPL files. Export to KiCad if you would rather finish there.
From idea to ordered board
- 1Describe
Type what you are building
Describe the project in everyday language, no schematic jargon required.
- 2Draft
Get a wired first pass
ProtoFlow wires the schematic and drops in real, orderable parts with the right footprints.
- 3Build
Lay it out and order it
Sync to the PCB editor, route by hand or with the auto-router, clear DRC, and export Gerbers for your favorite fab, with BOM and CPL files ready for JLCPCB assembly.
FAQ
Do I need to know KiCad?
No. ProtoFlow has its own schematic and PCB editors, so you can go from a description to Gerbers without learning another tool. If you already use KiCad, ProtoFlow opens and exports KiCad projects.
Is it really free?
Yes. The free plan includes the full editor and AI, with no card and no expiry. Paid plans raise AI usage limits.
Are the parts real?
Yes. You import actual distributor parts with real symbols and footprints, so your bill of materials is orderable.

Use caseSchematic capture
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.
ExploreUse casePart discovery
Find the parts you need from one place, with real symbols and footprints, instead of bouncing between datasheets, catalogs, and browser tabs.
ExploreWho it's forStudents
Lower the barrier from "blank schematic" to "working draft", then carry the design through simulation, layout and Gerbers, so you spend lab time understanding circuits, not fighting the tool.
