A real visitor’s prompt and circuit diagram

The original input and output, shown without rewriting.

A visitor typed

If you press S1, lamp A lights up and remains lit after you release it (self-holding). ● 2) Lamp B can only be switched on with S2 if lamp A is already lit. As long as A is not lit, S2 does nothing. 3) If you press S0 (common stop button), both lamps turn off — regardless of their state

What you can do with the download

SVG and PNG

Download SVG for a scalable vector image or PNG for a flat picture. To change the generated content here, revise the description and generate again.

Editing after download

The PNG has no editable shapes. Open the SVG in Inkscape to edit vector objects. To change relationships, connections or layout here, revise the description and generate again.

Limits worth knowing first

30 requests / hour

Per IP address. A shared network shares the limit. All attempts count, including failures. At the cap, wait an hour and try again.

2,000 characters

Maximum input length. Shorten the description to the details that matter.

20,000 per 24 hours

Site-wide request capacity over a rolling 24 hours. If it is reached, try again in an hour.

0 accounts

No signup or personal history. Download your result before closing the tab.

  • Generated circuits are drafts, not simulations or verified wiring instructions. Check connections, ratings and protection with a qualified engineer before use.

What happens to what you type

  1. We keep it

    Your description, generated output, full response, hashed IP address and operational metadata are saved so we can enforce limits and check quality. We don’t delete them automatically yet; email us to request deletion.

  2. Good circuit diagrams may appear in Examples

    Eligible prompts and results are shown publicly by default with the original prompt, until removed. Don’t enter names, client data or anything confidential.

  3. We never ask who you are

    No account, name, email or payment.

Scenario and reference pages

One tool for each engineering drawing

Choose the generator whose notation matches the job; the engine stays locked to that drawing type.

Circuit schematic

schematic maker

Turn a component-and-connection specification into a clean electrical or electronic schematic.

Circuit schematic

circuit diagram online

Draw a circuit diagram in the browser by describing its source, components, values, and nets.

Ladder logic

ladder logic generator

Create PLC ladder logic with contacts, coils, branches, addresses, and rung descriptions.

Single-line diagram

single line diagram maker

Lay out sources, transformers, transfer switches, buses, breakers, feeders, and loads in one-line notation.

Single-line diagram

electrical panel diagram

Draft the source, main protection, bus, branch breakers, ratings, and downstream loads for an electrical panel.

Circuit schematic

wiring diagram maker

Convert a wiring description into an explicit source-to-load connection diagram with labeled devices and nets.

Circuit schematic

free electrical schematic software

Use a free plain-English schematic generator when you need a fast first draft rather than a manual symbol palette.

Breadboard diagram

breadboard diagram maker

Place a microcontroller, parts, rails, and colored jumper wires into a physical breadboard layout.

P&ID

P&ID diagram maker

Draft process equipment, tagged instruments, process lines, signal lines, valves, and control loops.

Timing diagram

timing diagram maker

Plot clocks, resets, enables, buses, high-impedance states, and labeled data windows on aligned waveforms.

Logic gate diagram

logic gate diagram maker

Create a gate-level logic diagram from Boolean inputs, intermediate signals, and outputs.

Process

From specification to a drawing you can hand off

01

Name the drawing type

Choose a schematic, ladder, single-line, P&ID, breadboard, timing, or logic page.

02

List the components

Include ratings, tags, signals, connections, and operating states in plain English.

03

Generate the diagram

CircuitMaker.ai writes valid Schematex and renders the selected engineering notation.

04

Verify and export

Check every connection and rating, then download SVG or PNG or continue in ChatDiagram.

Details

Questions, answered plainly

Is CircuitMaker.ai related to Altium CircuitMaker?

No. CircuitMaker.ai is an independent plain-English AI drawing tool and is not affiliated with Altium or its CircuitMaker product.

Can I use the drawings for installation work?

Treat every result as a draft. Verify components, ratings, conductor sizes, protection, and code requirements with a qualified engineer or licensed electrician.

Which diagram types are supported?

The first release supports circuit schematics, ladder logic, single-line diagrams, P&IDs, breadboards, timing diagrams, and logic-gate diagrams.

Do I need an account to export?

No. SVG and PNG exports are available without signup, payment, or a watermark, subject to hourly fair-use limits.
