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.

About
ProtoFlow is an AI-native desktop electronic design automation (EDA) tool for schematic capture and PCB design. Describe a circuit in plain language to create an editable first draft, search real electronic parts and footprints, inspect datasheets, clean up wiring, and continue manually in familiar schematic and board editors. ProtoFlow supports ERC/DRC review, 3D board inspection, Git-backed versioning and visual diffs, comments and collaboration, plus manufacturing outputs including Gerber, drill, BOM, and placement files. Designs remain normal editable geometry, and users should verify symbols, footprints, connections, and manufacturing data before production. ProtoFlow can read and write native KiCad files and export to established EDA workflows. A free plan is available without a credit card, with paid options for higher AI usage. It is built for hardware engineers, makers, students, educators, researchers, and electronics startups.
