How it works

Describe it.
Refine it. Send it to fab.

Go from an idea to an editable PCB design without starting from a blank canvas.

Start with what the board should do

Describe the parts, power, and behavior you need. Get a real schematic you can inspect and edit right away.

Fix problems before you order

Check footprints, power, decoupling, and manufacturability. Resolve the important issues, then export for fabrication.

Why verification matters

“One thermal mistake turned a $40K tape-out into four weeks of rework and a $20K write-off.”
EE intern at a major chip manufacturerStory retold with permission. Identifying details removed.
$40KTape-out cost
$20KWritten off
4 weeksProject slip

That failure shaped our goal for the verification gate: surface costly errors before a board reaches fabrication.

Built for your IP

Your board stays yours.

Local-first projects

Your board lives in your browser or exported files. Only the context needed for an AI action is sent for processing.

No API keys to paste

Cherry Blossom provides the AI credits. There is no model-provider account to connect.

Standard outputs

Export editable KiCad projects, Gerbers, and BOMs. No lock-in.
