What do I need to run it?

A recent Chrome, Edge, or Firefox on a laptop or desktop. It's a browser app — nothing to install. It isn't built for phone-sized screens for actual drafting, since drawing a DB on a 6-inch screen isn't realistic for anyone.

Where does my drawing live? Is it uploaded anywhere?

Your drawing lives in your browser until you choose to export it (PDF, DXF, Excel/CSV) or save a file. Exporting sends the drawing to SLD Kit's export service to generate that file — that's the only time it leaves your browser during normal use.

What can I export?

Drawing as PDF or DXF (DXF includes a JSON topology sidecar, since DXF itself has no concept of electrical connectivity). Schedule and BOM as Excel, PDF, or CSV.

Does it guarantee SANS 10142-1 compliance?

No — it flags common issues (missing main switches, unconnected terminals, phase imbalance, missing warning-label content) as you draw, which catches a real class of mistakes early. It doesn't replace the judgement of a qualified person, and a drawing with no warnings isn't a certification of anything.

Can I add my own company logo and details to exports?

Yes — project settings let you set a company name, logo, and client details, which appear in the title block on every export.

Is it free?

Yes, right now, while it's in active early development. See pricing for where that's headed.

I found something wrong, or a validation rule that doesn't match how I'd actually do it on site.

That's exactly the kind of thing worth reporting — get in touch. Real feedback from people who actually draw DBs is what the validation rules and templates are being refined against.
