About ALT TAB

Building the future of PCB design

We build ALT TAB Circuit Copilot, an AI KiCad plugin that keeps the copilot in the schematic and PCB editors engineers already use. Faster boards, still your judgment on ERC and DRC.

Our story

ALT TAB started with a simple observation: hardware engineers spend countless hours on repetitive PCB tasks that could be accelerated with intelligent assistance.

Founded in 2024, we set out to build AI tools that understand PCB design—not just as images, but as structured engineering data with nets, footprints, and design rules.

Today, ALT TAB Circuit Copilot helps teams iterate faster, catch errors earlier, and focus on innovation instead of busywork.

What drives us

Our values

Innovation

We push boundaries in AI and hardware tooling, always exploring what is next.

Community

Open source and KiCad users are at the heart of everything we build.

Quality

Reliable, production-ready tools—not demos. Your boards depend on it.

Passion

We love hardware. Every feature reflects respect for the craft of PCB design.

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.
