Less figuring out the software. More figuring out the wiring.

A clear head starts
with a clear diagram.

Draw circuits with automotive components and labelled wires. An open canvas gives every connection room to make sense.

  1. 01

    Pick your parts

    Batteries, relays, connectors, and more. Start with built-in components and customise their labels and terminals.

  2. 02

    Make the connection

    Connect terminals, route your wires, and choose colours and labels that make each circuit easy to follow.

  3. 03

    Keep it all together

    Split your build across pages. Keep lighting, ignition, and accessories organised in one diagram.

Multi-user editing & sharing

Two sets of eyes. One shared diagram. Wire together in real time, or send a link to bring someone into your build.

Better with another set of eyes

Your build.
A shared perspective.

Work through a tricky circuit together. Invite someone into your diagram, see where they’re working, and keep the whole team on the same page.

  • Edit together in real time
  • Share a link to your diagram
  • Pick up on the web or iPad

Made to leave the screen

From the canvas
to the workbench.

Keep your diagram beside the build, send it to a mate, or file it away for the next owner. The work you put in stays easy to read.
