SmartSLD
Online electrical single-line diagram editor. With AI.
SmartSLD is an online editor for electrical single-line diagrams with an AI agent that builds them from a description or a photo. The status quo is frustrating. AutoCAD Electrical works but it's expensive and has a steep learning curve. Online diagram tools like draw.io are accessible, but they have no electrical-aware layout algorithm and no real component library. And none of them have AI.
I'm the maker. I built SmartSLD because I kept watching electrical contractors and solar installers wrestle AutoCAD for diagrams that are mostly the same 3 patterns. Utility, main breaker, bus, loads. Repeat.
The two existing options are bad in opposite ways. AutoCAD Electrical is the industry standard, but it's expensive and has a steep learning curve. Generic diagram tools like draw.io are easy to use but have no electrical layout algorithm and no real component library. And none of them have AI.
Three things I'm proud of:
1. The AI doesn't dump JSON at you. It calls atomic editor operations, so one prompt equals one undo. The diagram never gets into a "almost right" state where you have to manually patch the output.
2. The image-to-diagram works on hand-drawn sketches, not just clean schematics. Whiteboard photo turns into an editable SLD.
3. The editor core is open source: github.com/NovaShang/sldeditor
It's free, with a per-user daily AI quota (100 messages plus 20 image requests). Not a free-trial gimmick. That's literally what my OpenRouter bill can carry right now.
