Turn legacy complexity into instant understanding.
Humerus AI is an intelligent assistant built for industrial PLC environments. Our long-term vision is AI that observes, interprets, and interacts with PLC software the way human engineers do — through the screen. Until vision-only AI is mature enough, today we deploy a lightweight client on the customer's engineering PC that automatically captures and uploads PLC project data, with analysis and chat running in the cloud. We are steadily working toward a future with no integration and no on-site footprint.
A lightweight client today, cloud AI at work, zero integration as the end state.

Why Humerus AI
Industrial control systems suffer from a persistent problem:
Legacy PLC programs without documentation
Lost design intent and engineering context
Time-consuming debugging and logic tracing
Increasing maintenance complexity across multiple devices
Humerus AI directly addresses these challenges by transforming opaque PLC projects into structured, explainable, and maintainable systems.
Focus on innovation and not reverse engineering old logic.

What Humerus AI Does
1. Instant Program Understanding & Documentation
Automatically reconstructs:
- Control logic
- Process flows
- IO mapping
- Resource allocation
Transforms undocumented legacy programs into structured engineering knowledge.
2. Advanced Ladder Logic Analysis
Deep inspection of PLC programs to detect:
- Logical conflicts
- Redundant or dead code
- Timing issues
- Hidden operational risks
Reduces debugging time and prevents unexpected failures.
3. Engineering Knowledge Recovery
Rebuilds lost design intent from existing code:
- Infers original requirements
- Restores functional architecture
- Reconnects fragmented engineering context
Eliminates dependency on human memory.
4. Cross-Vendor Program Migration
Seamless conversion across PLC platforms:
- Vendor-specific adaptation
- Logic compatibility alignment
- Minimal manual rewriting
Accelerates system upgrades and platform transitions.
Core Technology
Long-term vision: vision-first, non-intrusive AI
The end-state is AI that interacts with PLC software purely through UI understanding and simulation — no hardware access, no protocol injection, no system intrusion. Until vision-only AI is mature enough, today we deploy a lightweight client on the customer's engineering PC to automatically capture and upload PLC project data, with analysis and chat running in the cloud.
- Lightweight on-site client
- Automatic capture & upload
- Cloud-side analysis & chat
Ensuring zero operational risk during deployment.
