Agentic Schematic Drafting
Describe your circuit in plain English. Our agent selects components, defines nets, and drafts the schematic directly in KiCad. No more manual symbol hunting.

ALT TAB Circuit Copilot Demo KiCad AI Plugin vs GPT-6 Astra: Full PCB Design From One Prompt
A real board, start to finish, in the editor — files changing as the agent runs. No condensed 15-second cut. This is the demo people ask for.
Context: GPT-6 Astra vs in-editor tools
OpenAI showed KiCad on the Astra launch page. We wrote what that actually means for PCB work — and how ALT TAB Circuit Copilot differs.
The Next Release
Circuit Copilot Version 2.
Natural language into schematic and PCB work inside KiCad. Version 2 is not public yet. If you already downloaded, we email you three days before release. Our custom-trained Ohm (formerly Electrode 1.0) model is built for electronics.

Capabilities
Engineered for Precision.
ALT TAB Circuit Copilot is a KiCad AI plugin: expert help stays inside KiCad — routing questions, components, documentation, and project context. Not a separate EDA. The copilot sits next to your schematic and PCB.
Smart Editing
Batch modify footprints, update values, or swap components across your entire project with a single command.
LiveDesign Rule Guard
Real-time AI analysis of your layout against industry standards and custom constraints.
BuildingAuto-Routing 2.0
Intelligent trace routing that respects signal integrity, differential pairs, and length matching.

Research
Ohm, an open-weight model for KiCad.
Ohm is ALT TAB’s open-weight language model for KiCad printed-circuit-board design. The 2026 Engineering TODAY conference paper published it as Electrode 1.0: a 3-billion-parameter model adapted on 33,055 real KiCad projects, two electronics textbooks, and the KiCad Library Convention. Training used domain-adaptive pretraining on KiCad S-expressions, then supervised fine-tuning on plugin tool-call traces, so the checkpoint can drive schematic and board edits through 60+ in-editor tools.
On a 100-task KiCad evaluation with substring-match scoring, Electrode 1.0 scored 0.5388 — 8.4% above the Qwen-Coder baseline and 4 percentage points above the previous in-house checkpoint. The public name is now Ohm.

KiCad AI
KiCad AI, inside the editor
KiCad does not ship AI. ALT TAB Circuit Copilot is an in-editor KiCad AI plugin — a copilot and chatbot next to your schematic and PCB. How KiCad AI works today.
No. KiCad ships no AI features of its own. “KiCad AI” means third-party tools: in-editor plugins, generators that export KiCad files, or AI that builds symbols and footprints. ALT TAB Circuit Copilot is an in-editor KiCad AI plugin — a copilot that runs inside schematic and PCB editors.
