How it works

Three simple steps to your perfect circuit

1

Describe Your Circuit

Tell the AI what you want to build in plain English. "Create a 1kHz low pass filter" or "Design an inverting op-amp with gain of 10".

2

Review & Customize

AI generates a complete SPICE netlist. Edit component values, add your own modifications, or ask AI for improvements.

3

Simulate & Export

Run simulations to verify your design, generate BOM for ordering parts, and share your circuit with the community.

Loved by engineers worldwide

KeliCAD has transformed how I prototype circuits. The AI suggestions are incredibly accurate.
