Describe a circuit in plain English and simulate it in your browser — voltages, motor torque, speed and thermal behaviour. Free, no account needed.
The Genuine Robotics Circuit Builder is a free, browser-based circuit design and simulation tool for robotics and electronics. Describe what you want in plain English and the AI assistant builds the circuit for you, or place and wire components yourself on a breadboard or schematic. Run the circuit to see real node voltages and currents solved by modified nodal analysis, and watch motors, LEDs and sensors respond with live telemetry for torque, speed and thermal behaviour.
No installation and no account are required to start: anonymous visitors get a guest session with a daily allowance of AI messages, and signing in with Google keeps it free while saving your projects. It is part of the Genuine Robotics platform, alongside the Structure Builder for CAD parts and the robotics physics simulator.
