CircuPilot designs and simulates electronic circuits in the browser. Describe a circuit in plain language, photograph a schematic from a book or whiteboard, or draw it by hand — then run a real ngspice simulation and copy the standard SPICE netlist out.
It covers analog circuits, digital logic gates with 74LS and 74HC packages, and Arduino firmware compiled and emulated alongside the analog simulation. Nothing to install, and no account is needed to try it.
