As a browser based circuit simulator, CircuitForge eliminates the need for expensive software licenses and complicated installations.
See your circuit the way it actually exists in space. Every component, every wire rendered in full 3D — not flat schematics. Rotate, zoom, and inspect from any angle.
Ask why your circuit isn't working. The AI explains component behavior, suggests fixes, and walks you through electronics concepts in plain language. No textbook needed.
No download, no account, no setup. Open CircuitForge in your browser and start placing components immediately. Create a free account only when you want to save your work.
This is a real CircuitForge circuit — running live in your browser right now. Not a screenshot. Not a video.
