About
Easy-wire mode lets you connect elements with fewer clicks and less frustration. Unit-aware expression evaluation lets you plot arbitrary signals of interest, such as differential signals or power dissipation. In-browser simulation and plotting lets you design and analyze faster, making sure your circuit works before ever picking up a soldering iron. Advanced simulation capabilities include frequency-domain (small signal) simulation, stepping circuit parameters through a range, arbitrary Laplace transfer function blocks, and more. Work with multiple signals easily with configurable plotting windows, vertical and horizontal markers, and calculations on signals. Draw generic rectangular symbols for IC or system-level wiring diagrams with just a few clicks.

About
CircuitSim is a full SPICE circuit simulator with a 3,000+ component library and a modern schematic editor. No install, free to get started. Built for students, educators, and professionals.
It runs in a browser tab and needs no admin rights, so it works on Chromebooks and locked-down school laptops. Run seven kinds of analysis: interactive, interactive operating point, transient, AC sweep, DC operating point, DC sweep, and parameter sweep. Results plot on oscilloscope-style charts, with probes you can drop anywhere in the circuit. Define custom parts from SPICE model text or import KiCad symbols.
CircuitSim also imports Multisim Live designs ahead of that product's retirement on September 15, 2026. It is the only browser tool that opens .csim, .ms14, and .msjs files, and it rebuilds the schematic with wiring, placement, net labels, probes, and simulation settings intact.
Classroom licensing adds seat assignment, anonymous student seats, and private student work.
