IndAutomation vs PLC AI — Which Tool Actually Fixes Your Faults?

PLC AI (plcai.app) is a chat-based assistant for PLC troubleshooting. IndAutomation is a full diagnostic platform: AI fault analysis, photo diagnosis, parts pricing, and the only MCP-native tool in industrial automation. Built for field techs who need answers and parts, not just chat.

Chat-only, PLC-only

FaultExpert is transparent: it is free during the open beta. Every feature is unlocked and nothing is for sale. PLC AI does not publicly list pricing. IndAutomation covers PLCs plus VFDs, conveyors, packaging, HVAC, and more.

Why Field Techs Choose IndAutomation

Photo diagnosis is a game changer. Snap a photo of a faulted HMI screen, a tripped VFD, or a panel fault indicator. IndAutomation's AI vision analyzes the image and returns probable causes with fix steps. PLC AI does not offer this.
More than just PLCs. PLC AI focuses on programmable logic controllers. IndAutomation covers Allen-Bradley PLCs, VFDs (PowerFlex, ABB, Yaskawa), conveyors, packaging machines, HVAC systems, and Siemens equipment. One tool for the whole plant.
Parts with pricing, not just advice. IndAutomation recommends replacement parts with current pricing. No second lookup needed. Diagnose the fault and order the part in the same session.
MCP-native — the only one. IndAutomation publishes an MCP server. Connect it to Claude, Cursor, or any MCP-compatible AI tool. No other industrial diagnostic platform offers this integration.

Bottom Line

PLC AI is a useful chat tool if your work is limited to PLCs. But if you are a field tech who works across multiple equipment types, needs photo-based diagnosis, wants parts with pricing, or uses AI tools like Claude — FaultExpert is built for your workflow. Free during beta. No lock-in.
