PLCcode.ai
Paid browser workspace for Studio 5000 L5X and L5K projects, with AI grounded in the open project.
Who it's for
Controls engineers drafting or reading PLC projects outside one vendor IDE. A check in the browser is not a download, and a download is not a test on the machine.
Caveat / limitations
Rockwell Studio 5000 import, edit, and export today. The pricing page says Siemens and CODESYS are coming. Standard was listed at $20 a month when checked, with more AI on higher tiers and a quoted enterprise plan that can be self-hosted. Cloud plans store the project and send questions to the model you pick. Their own homepage says AI output can be wrong and to test it before it touches equipment. PLCconnect, the plant-network link, is marked coming soon, so this is not a live controller session yet.
