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.

01 | THE PROBLEM
The tool should not be the hard part
01
Traditional EDA has a brutal learning curve for a weekend build.
02
Figuring out which parts exist — and which you can actually buy — is half the battle.
03
You want to build the project, not fight symbol libraries.
02 | HOW PROTOFLOW HELPS
Parts you can actually order
Search across distributors in one place and drop in real parts with the right footprints.
Free to start
Get from idea to a clean draft without a license, then hand it to free KiCad for layout.
03 | 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.
3Export
Send it to KiCad and order
Export a tidy KiCad project, lay out the board, and order it from your favorite fab.
04 | FAQ
Do I need to know KiCad?
Not to start. ProtoFlow gets you a clean schematic from a description; take it into free KiCad when you are ready to lay out the board.
Is it really free?
Yes, it is free to start, with paid plans when you want more AI help and higher limits.
Are the parts real?
Yes. You import actual distributor parts with real symbols and footprints, so your bill of materials is orderable.
