AI Circuit Explainer
Describe any electronic circuit — or paste component values — and get an instant plain-English explanation of exactly how it works. Built for electronics students and beginners.
How It Works
01
Describe your circuit
Type a description or paste component values. Any level of detail works — from basic to complex.
02
AI analyses it
Our AI explains what each component does, how they interact, and what the circuit produces.
03
Simulate it live
Open the free simulator to see the circuit running in real time and verify the explanation.

Frequently Asked Questions
How does the AI Circuit Explainer work?
Describe your circuit — its components, values and how they connect — and click Explain. Your circuit opens in ChatGPT in a new tab with a ready-made prompt asking for what it does, how it works, the role of each component and any key calculations. You can also copy the prompt and paste it into Claude, Gemini, Copilot or any other AI.
Is the AI Circuit Explainer free?
Yes. Using it costs nothing and you don't need an account on FreeCircuitSim. ChatGPT can be used without logging in, though its own free-tier limits apply.
What circuits can I ask about?
Any electronic circuit — resistor networks, voltage dividers, RC and RL filters, rectifiers, transistor switches, op-amp circuits, 555 timers, logic gates and more. Including component values gets you specific calculations such as cutoff frequency, gain or timing.
