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.
The parts you need. A canvas that makes sense. Draw, connect, and share your next build, from the first idea to the workbench.
Free to start. No credit card required.
Less figuring out the software. More figuring out the wiring.
Draw circuits with automotive components and labelled wires. An open canvas gives every connection room to make sense.
A silent product demonstration with a visible mouse cursor dragging the battery, fuse, and headlights around the canvas while their wires stay connected.
Batteries, relays, connectors, and more. Start with built-in components and customise their labels and terminals.
Connect terminals, route your wires, and choose colours and labels that make each circuit easy to follow.
Split your build across pages. Keep lighting, ignition, and accessories organised in one diagram.

Better with another set of eyes
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.
Made to leave the screen
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.
