Describe a machine in plain English and get IEC 61131-3 structured text, ladder and FBD. A deterministic compiler checks every draft, a browser simulator runs it, and an OPC UA endpoint lets your HMI drive it. Free in alpha.

Hi Product Hunt! PLC programming still means a slow edit-compile-download loop, and most AI tools for it just guess. I built PLC-Ladder so you can describe a machine in plain English ("start the conveyor 5 seconds after the start button") and get IEC 61131-3 structured text, a ladder diagram and an FBD.
The key rule: the AI never writes the final result. It drafts, a deterministic compiler parses, type-checks and simulates every line, and you approve each change. Every assumption it makes (like an added E-stop or a 3 s dwell) is listed for you to review.
What you can do today, free in the browser:
Plain English to ST, ladder and FBD, always in sync
Edit the ladder directly and watch it run scan by scan
Timers, counters, latches, edge detection, REAL math and your own function blocks
Expose the running simulation over OPC UA so your HMI (Ignition, WinCC, UaExpert) can drive it
It's useful for automation engineers, system integrators and students learning ladder logic. I'd love feedback on which vendor export (CODESYS, TIA Portal, Studio 5000) you'd want first, and on any logic it gets wrong.
