AI circuit simulator
Most simulators make you place every part before you can press play. Here you describe the circuit — or photograph a sketch of it — and the AI drafts a real schematic with real components, ready to run.

The gap between "I have an idea" and "I can see whether it works" is usually an hour of drawing. This closes it to about a minute.
Step 01
Type it in plain English, or upload a photo of a sketch. No netlist, no part placement, no library hunting first.
Step 02
The AI picks actual components with accurate pinouts and footprints and wires them to spec — that is what makes the result worth simulating.
Step 03
Watch what the circuit does, adjust a value by hand or ask the AI for a change, and run it again before you touch a breadboard.
Every one of these costs minutes on screen and an afternoon with a multimeter.
A blinker meant for one flash a second that actually runs at four. Watch the output swing and read the period off the plot instead of counting flashes on a breadboard.
A current-limiting resistor an order of magnitude too small will show up as a current no LED survives — before you solder it in.
An amplifier whose divider pins the transistor into saturation or cutoff clips or flatlines on screen, where the fix costs one number.
A node that looks joined but is not behaves very differently in simulation than the circuit you intended — a dead branch is obvious immediately.
A rail that sags the moment the load switches on tells you the problem is the supply, not the part you were about to replace.
A filter that rolls off an octave away from where you wanted it, or a divider that lands just outside the range your input expects, is a one-number fix on screen.
"Blink an LED once per second from a 9V battery" produces the circuit on the left and the behaviour on the right. Both are editable; changing R2 moves the trace.
Analogue stages, sensor front-ends, timing networks — the same loop of describe, draft, simulate and refine applies to all of them.
Worth saying plainly, because plenty of tools imply otherwise.
An AI circuit simulator is very good at catching the mistakes that come from a slip of arithmetic or a wire in the wrong place. It is not a substitute for your own engineering judgment, for a datasheet, or for measuring the thing you actually built. Treat a clean simulation as permission to order parts — not as proof that a design is safe.
That goes double for anything involving mains voltage, battery packs at appreciable current, or a circuit someone else will rely on. Simulate it, review it, then test it on the bench.
Credits are spent generating and revising circuits with AI. Editing, simulating and re-running a circuit you already have never costs a credit.

If you are coming from a traditional simulator, the short version is: you skip the drawing, and everything after that is familiar.
An AI circuit simulator builds the circuit for you and then runs it. Instead of placing every part and wire by hand before you can press play, you describe the circuit in plain English — or upload a photo of a sketch — and the AI drafts a real schematic with actual components, which you can then simulate and edit.
Yes. Type something like "555 timer that blinks an LED once per second from a 9V battery" and you get a complete schematic with real parts and values, ready to simulate. You never have to draw it first.
Yes. Photograph a whiteboard or a page from your notebook and the AI redraws it as a clean, labeled schematic. From there it behaves exactly like a circuit you described in text — editable, simulatable and exportable.
No. There is no netlist to write and no simulation profile to configure before you see a result — the circuit arrives ready to run, so you can spend your time on the design rather than the tooling.
The common, expensive mistakes: a timing network that gives the wrong rate, a resistor that lets far too much current through an LED, a bias network that puts a transistor in the wrong region, or a wire that never actually connects. All of them are free to fix on screen and tedious to fix on a breadboard.
Yes. Change values or wiring by hand, or ask the AI for a change in chat, then run it again. Edits and re-runs do not cost you a redraw.
No, and you should not treat it as a substitute. Simulation catches design and wiring mistakes early, but every AI-generated circuit still needs your engineering judgment — and real measurement — before you build anything that matters or anything involving mains power.
Every plan starts with a 7-day free trial and includes simulation. A card is required to start the trial, and you can cancel anytime before it ends.
