How it works
Three simple steps to your perfect circuit
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".
Review & Customize
AI generates a complete SPICE netlist. Edit component values, add your own modifications, or ask AI for improvements.
Simulate & Export
Run simulations to verify your design, generate BOM for ordering parts, and share your circuit with the community.
