v1.0 live

An AI Copilot
for KiCad.

Reference circuit modules for KiCad: LDOs, MCU bring-ups, sensor frontends. Every module is reviewed, ERC-clean, and includes the passives each chip requires. Browse the library and inspect every design the engine produced.

First release of kicad-copper. A fork of KiCad with an embedded Copper chat panel in the schematic editor. Describe a circuit in natural language and the Copper backend generates a clean schematic, applied directly to your live editor. Release notes.

Capabilities01 / 04

What Copper does.

Every module is reviewed by humans and the engine. Every generated design includes its scorecard, ERC report, and intermediate representation.

01library

Reviewed reference modules

Every module is reviewed and ERC-clean. The required passives are included: bypass caps, pull-ups, crystal loads.

  • LDOs, MCU bring-ups, sensor frontends
  • Reviewed by humans and the engine
  • Versioned, with approval audit trails
02engine

Generated designs are inspectable

Every board includes its IR, rendered schematic, ERC report, and a self-assessment scorecard.

  • Schematic SVG and intermediate representation
  • ERC pass / warn / fail with messages
  • Per-design scorecard with weighted checks
03grounding

Datasheet-grounded

Modules cite their datasheet origin. Decoupling values come from the datasheet, not from the model.

  • Direct datasheet citations on every part
  • License field on every module
  • Provenance JSON saved per version
04promise

Deterministic

Run the same prompt twice, get the same board. The compiler is deterministic.

  • Same prompt produces the same IR and schematic
  • Reviewable version diffs
  • Stable engine contract
How it works
01

Browse the library

Search reference modules by type. See which are approved and which are still in review.

02

Inspect any design

Open a board, read its scorecard, and see which modules it uses.

03

Review the output

Every approval is recorded. Every design includes its ERC report and scorecard.

Every design is reviewable

Every design includes its scorecard.

Every board the engine produces includes its IR, rendered schematic, ERC report, and a self-assessment scorecard. You can see exactly what is in the design before you fabricate it.
