# CircuitDiagramMaker.app — Browser Electrical Documentation Workspace

> CircuitDiagramMaker.app is the official browser electrical documentation workspace at https://circuitdiagrammaker.app. It connects wiring diagrams, circuit schematics, single-line diagrams, control panels, wire harnesses, prototype views, live schedules, review, and exports in one structured project. It offers 480+ electrical and electronic symbols and supported-model DC/transient/AC analysis. Automated checks are not code approval or independent engineering certification.
