Describe it. Generate it. Validate it.

AIPE Sketcher turns a circuit description into a clean SVG schematic and checks that the drawing is electrically faithful to it. Describe the circuit to Codex or Claude Code in plain English, or name a reference converter, and AIPE Sketcher draws it with a standard symbol library and reports what it checked.

It installs as a native plugin in Codex and Claude Code. Drawing and validation run locally on your computer: it needs Python 3.9 or newer, and no API key, cloud service or extra package installation.

The 99-second Quick Start video above shows the installation and a first schematic. It has captions and no sound. Its Codex and Claude Code windows are simplified reconstructions of the apps, not screen recordings; the agent replies and the schematic come from a real run.

Install with Codex

In the Codex app (Codex in the ChatGPT desktop app works too):

1. Open Codex.
2. Go to Plugins.
3. Choose Add a marketplace, enter FulongLi/AIPE-Sketcher as the source and confirm with Add marketplace.
4. Select AIPE Sketcher in the list and click Install.
5. Start a new chat and describe the circuit you want.

Prefer the command line? Run these two commands, then restart Codex:

codex plugin marketplace add FulongLi/AIPE-Sketcher

codex plugin add aipe-sketcher@aipe-sketcher

Install with Claude Code

In a Claude Code session, enter these two commands one at a time:

/plugin marketplace add FulongLi/AIPE-Sketcher

/plugin install aipe-sketcher@aipe-sketcher

From a terminal, the same steps are claude plugin marketplace add FulongLi/AIPE-Sketcher and claude plugin install aipe-sketcher@aipe-sketcher. Claude uses AIPE Sketcher on its own when you ask for a schematic; you can also call it as /aipe-sketcher:schematic.

Both apps need Python 3.9 or newer (python3 on macOS and Linux, py -3 on Windows) for the local drawing engine. Updating, removing and checking an installation are covered in the repository’s plugin installation guide.

Generate your first schematic

Once the plugin is installed, start a new chat and paste this request:

Using AIPE Sketcher, generate a Dual Active Bridge converter schematic, validate the electrical connections, and export the result as SVG.

The agent writes the circuit, draws it, checks it and replies with links to the SVG schematic and its validation report, along with any assumptions it made. You can then continue in plain language: “label the transformer turns ratio,” “add an output inductor,” or “draw a synchronous buck converter instead.”

For your own circuit, include whatever you already know: the topology or purpose, the components and important values, how they connect, the labels you want and an output filename. For example:

Using AIPE Sketcher, draw a buck converter with a 48 V input, a MOSFET, a diode, a 100 µH inductor, a 470 µF output capacitor and a 10 Ω load. Label the input and output, and ask me before assuming any connection I have not specified.

What it can do

• Generate electrical schematics from circuit descriptions given in plain language through your AI agent.
• Draw common power-electronics reference topologies by name, including buck, boost, half and full bridge, dual active bridge, LLC resonant and three-phase inverter circuits.
• Arrange symbols and connections automatically: component placement, wire routing and labels.
• Validate the drawing against the electrical circuit: it reads the connections back from the drawn wires and refuses to save a drawing that differs from the circuit.
• Export SVG schematics and JSON validation reports.
• Run locally through Codex, Claude Code or the standalone Python command line.

What files you get

• SVG schematic (.svg): open it in a browser or edit it in a vector tool such as Inkscape.
• Validation report (.report.json): electrical validation, drawing connectivity, layout quality, and the assumptions and limitations of that drawing.
• Circuit description (.json): the components, ports and connections that were drawn, so the schematic can be revised and regenerated.

Developers can use the same engine without an agent through the aipe-sketcher command line or the Python API; see the command-line guide. AIPE Sketcher does not export SPICE, simulation models or PCB files.

Before you use the result

Validation confirms that the drawing matches the circuit it was given. It does not establish component ratings, hardware safety or circuit performance. Review component orientation, values, labels, the assumptions in the report and every warning before using the drawing in engineering work.

Complex or ambiguous circuits may need more detail in your request, and not every symbol or layout is supported yet; unsupported cases are reported rather than drawn. Architecture, known limits and test details are in the repository README.
